IBM Business Process Manager 8.0, 8.5, and 8.6 and IBM Business Automation Workflow 18.0 and 19.0 could allow a remote attacker to bypass security restrictions, caused by the failure to perform insufficient authorization checks. IBM X-Force ID: 181126.

NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.3 and 2.12.12, an authenticated MQTT client could subscribe to the internal $MQTT.deliver.pubrel subject family, bypassing configured subscribe permissions and exposing MQTT QoS2 protocol metadata for sessions in the account. This issue is fixed in versions 2.14.3 and 2.12.12.

Gogs is an open source self-hosted Git service. In 0.14.3 and earlier, any authenticated user can watch a private repository they have no access to, because the access check in the Watch API handler is inverted. The code checks if repoCtx.ViewerCanRead() (returns 404 when the user CAN read) instead of if !repoCtx.ViewerCanRead() (return 404 when the user CANNOT read). Once watching, the attacker's dashboard activity feed shows commit messages, branch names, issue titles, and PR details from the private repository. If email notifications are enabled, the attacker also receives emails containing issue and comment content.

A regular Zabbix user with no permission to the Monitoring -> Problems view is still able to call the problem.view.refresh action and therefore still retrieve a list of active problems.

Multiple vulnerabilities in the web management framework of Cisco IOS XE Software could allow an authenticated, remote attacker with read-only privileges to gain unauthorized read access to sensitive data or cause the web management software to hang or crash, resulting in a denial of service (DoS) condition. For more information about these vulnerabilities, see the Details section of this advisory.

Improper authorization in Nextcloud server 17.0.0 causes leaking of previews and files when a file-drop share link is opened via the gallery app.

Editors/LogViewerController.cs in Umbraco through 8.9.1 allows a user to visit a logviewer endpoint even if they lack Applications.Settings access.

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.179, when creating a conversation from a message in another conversation, there is no check to ensure that the user has the ability to view this message. Thus, the user can view arbitrary messages from other mailboxes or from other conversations to which they do not have access (access restriction to conversations is implemented by the show_only_assigned_conversations setting, which is also not checked). This issue has been patched in version 1.8.179.

An issue was discovered in MantisBT before 2.24.4. Due to insufficient access-level checks, any logged-in user allowed to perform Group Actions can get access to the Summary fields of private Issues via bug_arr[]= in a crafted bug_actiongroup_page.php URL. (The target Issues can have Private view status, or belong to a private Project.)

SeaweedFS is a distributed storage system. In versions 4.08 through 4.33, requests signed with SigV4 service s3tables are routed to the S3Tables management API where authorization collapses account-less S3 identities into the shared admin account and fails open, allowing an authenticated low-privileged S3 user to enumerate administrator-owned table bucket names and ARNs. This issue is fixed in version 4.34.

Mattermost versions <11 fail to properly restrict access to archived channel search API which allows guest users to discover archived public channels via the `/api/v4/teams/{team_id}/channels/search_archived` endpoint

An Authorization Bypass vulnerability in the Marmind web application with version 4.1.141.0 allows users with lower privileges to gain control to files uploaded by administrative users. The accessed files were not visible by the low privileged users in the web GUI.

Snipe-IT is an IT asset/license management system. Prior to 8.6.2, when Full Multiple Companies Support and scope_locations_fmcs are enabled, the API location creation endpoint detects an invalid parent-child company mismatch but does not return immediately, allowing creation of a child location under a parent location from a different company. This issue is fixed in version 8.6.2.

The l10nmgr (aka Localization Manager) extension before 7.4.0, 8.x before 8.7.0, and 9.x before 9.2.0 for TYPO3 allows Information Disclosure (translatable fields).

Snipe-IT is an IT asset/license management system. Prior to 8.6.2, UsersController::show() and printInventory() authorize only user viewing before loading and rendering assigned license, accessory, and consumable relationships, allowing an authenticated user with only users.view to see inventory and cost/order metadata from modules that direct permissions would otherwise deny. This issue is fixed in version 8.6.2.

Jenkins Health Advisor by CloudBees Plugin 3.2.0 and earlier does not correctly perform a permission check in an HTTP endpoint, allowing attackers with Overall/Read permission to view that HTTP endpoint.

A missing permission check in Jenkins Amazon EC2 Plugin 1.50.1 and earlier in form-related methods allowed users with Overall/Read access to enumerate credentials ID of credentials stored in Jenkins.

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.9 before 18.10.7, 18.11 before 18.11.4, and 19.0 before 19.0.1 that under certain conditions could have allowed a blocked Project Access Token to continue accessing private resources due to incorrect authorization enforcement.

Mattermost versions 10.5.x <= 10.5.4, 9.11.x <= 9.11.13 fail to properly restrict API access to team information, allowing guest users to bypass permissions and view information about public teams they are not members of via a direct API call to /api/v4/teams/{team_id}.

Mattermost versions <11.0 fail to properly enforce the "Allow users to view archived channels" setting which allows regular users to access archived channel content and files via the "Open in Channel" functionality from followed threads

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.11 before 18.11.1 that could have allowed an authenticated user to access titles of confidential or private issues in public projects due to improper access control in the issue description rendering process.

An issue has been discovered in GitLab CE/EE affecting all versions from 18.0 before 18.0.1. In certain circumstances, a user with limited permissions could access Job Data via a crafted GraphQL query.

Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.73.23 and 6.20.0, an authenticated Control Panel user could view metadata and content for resources they don't have permission to view, including entries, assets, users, roles, groups, and other configured resources. Depending on the resource, this could expose titles, custom field values, entry content, asset metadata, and the existence of users, roles, and groups. No data could be modified. This has been fixed in 5.73.23 and 6.20.0.

NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.3 and 2.12.12, MQTT retained message delivery and QoS1+ durable replay could deliver messages whose original topics matched a subscriber configured subscribe deny rule because these delivery paths did not consistently recheck the concrete original topic before sending the MQTT PUBLISH to the subscriber. This issue is fixed in versions 2.14.3 and 2.12.12.

Twig is a template language for PHP. Prior to 3.26.0, the column filter passes object arrays to PHP array_column(), which reads public and magic properties without reaching CoreExtension::getAttribute() or SandboxExtension::checkPropertyAllowed(), allowing an untrusted template author with column in allowedFilters to read properties that are not in the sandbox allowlist. This issue is fixed in version 3.26.0.

Solidtime is an open-source time-tracking app. Prior to version 0.12.2, Solidtime defines an explicit invitations:view and members:view permissions that gates the official invitations and members API. The Jetstream web team page authorizes access with only belongsToTeam() and then loads and serializes all pending invitation emails as well as members into Inertia props. Any employee who belongs to the organization can read pending invitation email addresses and members through the serialised inertia data in the team page body even though the same user is forbidden from the API. This issue has been patched in version 0.12.2.

An issue has been discovered in GitLab EE/CE affecting all versions starting from 16.9 before 17.7.7, all versions starting from 17.8 before 17.8.5, all versions starting from 17.9 before 17.9.2 could allow unauthorized users to access confidential information intended for internal use only.

A flaw was found in Moodle. Insufficient capability checks in a messaging web service allowed users to view other users' names and online statuses.

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, GET /history/<service>/<server_ip> re-uses the server_ip path parameter as a user-id when service == 'user', with no authorization check. Any authenticated user — even a guest in an unrelated group — can list any other user's full action audit trail (server IPs touched, configs deployed, services restarted). At time of publication, there are no publicly available patches.

Backstage is an open framework for building developer portals. Prior to 0.6.11, the unprocessed entities read endpoints in @backstage/plugin-catalog-backend-module-unprocessed do not enforce permission authorization checks. Any authenticated user can access unprocessed entity records regardless of ownership. This is an information disclosure vulnerability affecting Backstage installations using this module. This is patched in @backstage/plugin-catalog-backend-module-unprocessed version 0.6.11, @backstage/plugin-catalog-unprocessed-entities-common version 0.0.15 and @backstage/plugin-catalog-unprocessed-entities version 0.2.30.

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, the _validate_collection_access function uses an incomplete allowlist that only enforces ownership checks for collections matching user-memory-* and file-* patterns. All other collection names pass through unchecked — including the system-level knowledge-bases meta-collection, which stores the IDs, names, and descriptions of every knowledge base on the instance. Any authenticated user can query this meta-collection directly via the retrieval query endpoints to obtain a global index of all knowledge bases across all users. This vulnerability is fixed in 0.9.0.

MariaDB server is a community developed fork of MySQL server. From versions 11.4.1 to before 11.4.11, 11.8.1 to before 11.8.7, and 12.3.1, a user getting EXECUTE access to a stored routine via a role, could see the routine definition even without SHOW CREATE ROUTINE privilege. This issue has been patched in versions 11.4.11, 11.8.7, and 12.3.2.

etcd is a distributed key-value store for the data of a distributed system. Prior to 3.4.44, 3.5.30, and 3.6.11, a vulnerability in etcd allows read access via PrevKv, or lease attachment in Put requests within transaction operations, to bypass RBAC authorization checks. An authenticated user without sufficient read or lease-related permissions may be able to access unauthorized data or attach leases by invoking transaction operations with these features enabled. This vulnerability is fixed in 3.4.44, 3.5.30, and 3.6.11.

phpMyFAQ before 4.1.2 contains an insufficient authorization vulnerability in admin-api routes that allows authenticated ordinary users to access administrative endpoints by only checking login status instead of verifying backend privileges. Attackers with valid frontend user accounts can access sensitive backend operational information including dashboard versions, LDAP configuration, Elasticsearch statistics, and health-check data.

Mattermost versions 10.7.x <= 10.7.0, 10.5.x <= 10.5.3, 9.11.x <= 9.11.12 fails to properly enforce access control restrictions for System Manager roles, allowing authenticated users with System Manager privileges to view team details they should not have access to via direct API requests to team endpoints, even when explicitly configured with 'No access' to Teams in the System Console.

SiYuan is an open-source personal knowledge management system. Prior to 3.7.0, broken access control in the searchAsset, searchTag, searchWidget, and searchTemplate publish-mode Readers can enumerate metadata from documents that are invisible to the publish service. This vulnerability is fixed in 3.7.0.

OpenClaw before 2026.4.20 contains a scope enforcement bypass vulnerability in the assistant-media route that allows trusted-proxy callers without operator.read scope to access protected assistant-media files and metadata. Attackers can bypass identity-bearing HTTP auth path scope validation to retrieve sensitive media content within allowed media roots.

An issue has been discovered in GitLab CE/EE affecting all versions from 17.9 before 18.0.5, 18.1 before 18.1.3, and 18.2 before 18.2.1 that could have allowed an unauthorized user to access custom service desk email addresses.

A flaw was discovered in Moodle. Additional checks were required to ensure that users can only access cohort data they are authorized to retrieve.

OpenClaw before 2026.3.31 contains a session visibility bypass vulnerability where the session_status function fails to enforce configured tools.sessions.visibility restrictions for unsandboxed invocations. Attackers can invoke session_status without sandbox constraints to bypass session-policy controls and access restricted session information.

Audiobookshelf is a self-hosted audiobook and podcast server. Prior to 2.32.2, the GET /api/collections and GET /api/collections/:id endpoints return collections from all libraries without checking whether the requesting user has access to each collection's library. An authenticated user with access to any library can enumerate and read collections (including full book metadata) from libraries they are explicitly restricted from accessing. This vulnerability is fixed in 2.32.2.

A vulnerability was found in moodle before versions 3.6.3, 3.5.5 and 3.4.8. Permissions were not correctly checked before loading event information into the calendar's edit event modal popup, so logged in non-guest users could view unauthorised calendar events. (Note: It was read-only access, users could not edit the events.)

The Jetpack WordPress plugin does not have proper authorisation in one of its REST endpoint, allowing any authenticated users, such as subscriber to read arbitrary feedbacks data sent via the Jetpack Contact Form

An issue has been discovered in GitLab EE affecting all versions from 13.3 before 17.11.6, 18.0 before 18.0.4, and 18.1 before 18.1.2 that could have allowed authenticated project owners to bypass group-level forking restrictions by manipulating API requests.

Lychee is a free, open-source photo-management tool. Prior to 7.5.4, a SQL operator-precedence bug in SharingController::listAll() causes the orWhereNotNull('user_group_id') clause to escape the ownership filter applied by the when() block. Any authenticated non-admin user with upload permission who owns at least one album can retrieve all user-group-based sharing permissions across the entire instance, including private albums owned by other users. This vulnerability is fixed in 7.5.4.

Mattermost versions 9.10.x <= 9.10.1, 9.9.x <= 9.9.2, 9.5.x <= 9.5.8 fail to limit access to channels files that have not been linked to a post which allows an attacker to view them in channels that they are a member of.

OpenClaw before 2026.5.12 contains a privilege escalation vulnerability in Slack plugin approvals that allows exec-authorized users to resolve plugin approvals through the exec approver gate. Attackers with limited exec approval permissions can bypass intended approval splits to approve plugin actions outside operator configuration.

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.8.0-alpha.7 and 8.6.75, the GET /sessions/me endpoint returns _Session fields that the server operator explicitly configured as protected via the protectedFields server option. Any authenticated user can retrieve their own session's protected fields with a single request. The equivalent GET /sessions and GET /sessions/:objectId endpoints correctly strip protected fields. This vulnerability is fixed in 9.8.0-alpha.7 and 8.6.75.

The OG access fields (visibility fields) implementation in Organic Groups (OG) module 7.x-2.x before 7.x-2.3 for Drupal does not properly restrict access to private groups, which allows remote authenticated users to guess node IDs, subscribe to, and read the content of arbitrary private groups via unspecified vectors.

OpenClaw before 2026.3.24 contains an authorization bypass vulnerability in the HTTP /v1/models endpoint that fails to enforce operator read scope requirements. Attackers with only operator.approvals scope can enumerate gateway model metadata through the HTTP compatibility route, bypassing the stricter WebSocket RPC authorization checks.
