Multiple versions of GitLab expose sensitive user credentials when assigning a user to an issue or merge request. A fix was included in versions 8.15.8, 8.16.7, and 8.17.4, which were released on March 20th 2017 at 23:59 UTC.

An improper access control flaw in all versions of GitLab CE/EE starting from 13.9 before 14.2.6, all versions starting from 14.3 before 14.3.4, and all versions starting from 14.4 before 14.4.1 exposes private email address of Issue and Merge Requests assignee to Webhook data consumers

Missing authorization in GitLab EE versions between 12.4 and 14.3.6, between 14.4.0 and 14.4.4, and between 14.5.0 and 14.5.2 allowed an attacker to access a user's custom project and group templates

Improper access control in GitLab CE/EE affecting all versions starting from 10.7 before 14.3.6, all versions starting from 14.4 before 14.4.4, all versions starting from 14.5 before 14.5.2, allows an attacker in possession of a deploy token to access a project's disabled wiki.

In all versions of GitLab CE/EE since version 11.10, an admin of a group can see the SCIM token of that group by visiting a specific endpoint.

Improper access control allows any project member to retrieve the service desk email address in GitLab CE/EE versions starting 12.10 before 14.3.6, all versions starting from 14.4 before 14.4.4, all versions starting from 14.5 before 14.5.2.

Lack of an access control check in the External Status Check feature allowed any authenticated user to retrieve the configuration of any External Status Check in GitLab EE starting from 14.1 before 14.3.6, all versions starting from 14.4 before 14.4.4, all versions starting from 14.5 before 14.5.2.

GitLab Community and Enterprise Editions before 10.1.6, 10.2.6, and 10.3.4 are vulnerable to an authorization bypass issue in the Projects::MergeRequests::CreationsController component resulting in an attacker to see every project name and their respective namespace on a GitLab instance.

In all versions of GitLab EE starting from 13.10 before 14.1.7, all versions starting from 14.2 before 14.2.5, and all versions starting from 14.3 before 14.3.1 a specific API endpoint may reveal details about a private group and other sensitive info inside issue and merge request templates.

In all versions of GitLab EE since version 14.1, due to an insecure direct object reference vulnerability, an endpoint may reveal the protected branch name to a malicious user who makes a crafted API call with the ID of the protected branch.

In all versions of GitLab CE/EE since version 14.1, an improper access control vulnerability allows users with expired password to still access GitLab through git and API through access tokens acquired before password expiration.

Improper authorization checks in all versions of GitLab EE starting from 13.11 before 14.1.7, all versions starting from 14.2 before 14.2.5, and all versions starting from 14.3 before 14.3.1 allows subgroup members to see epics from all parent subgroups.

In all versions of GitLab CE/EE since version 11.3, the endpoint for auto-completing Assignee discloses the members of private groups.

In all versions of GitLab EE since version 8.13, an endpoint discloses names of private groups that have access to a project to low privileged users that are part of that project.

In all versions of GitLab CE/EE since version 8.0, access tokens created as part of admin's impersonation of a user are not cleared at the end of impersonation which may lead to unnecessary sensitive info disclosure.

In all versions of GitLab CE/EE since version 12.0, a lower privileged user can import users from projects that they don't have a maintainer role on and disclose email addresses of those users.

Permissions rules were not applied while issues were moved between projects of the same group in GitLab versions starting with 10.6 and up to 14.1.7 allowing users to read confidential Epic references.

GitLab versions 8.9.x and above contain a critical security flaw in the "import/export project" feature of GitLab. Added in GitLab 8.9, this feature allows a user to export and then re-import their projects as tape archive files (tar). All GitLab versions prior to 8.13.0 restricted this feature to administrators only. Starting with version 8.13.0 this feature was made available to all users. This feature did not properly check for symbolic links in user-provided archives and therefore it was possible for an authenticated user to retrieve the contents of any file accessible to the GitLab service account. This included sensitive files such as those that contain secret tokens used by the GitLab service to authenticate users. GitLab CE and EE versions 8.13.0 through 8.13.2, 8.12.0 through 8.12.7, 8.11.0 through 8.11.10, 8.10.0 through 8.10.12, and 8.9.0 through 8.9.11 are affected.
