CKAN MCP Server: SSRF via base_url allows access to internal networks

CKAN MCP Server is a tool for querying CKAN open data portals. Versions prior to 0.4.85 provide tools including ckan_package_search and sparql_query that accept a base_url parameter, making HTTP requests to arbitrary endpoints without restriction. A CKAN portal client has no legitimate reason to contact cloud metadata or internal network services. There is no URL validation on base_url parameter. No private IP blocking (RFC 1918, link-local 169.254.x.x), no cloud metadata blocking. The sparql_query and ckan_datastore_search_sql tools also accept arbitrary base URLs and expose injection surfaces. An attack can lead to internal network scanning, cloud metadata theft (IAM credentials via IMDS at 169.254.169.254), potential SQL/SPARQL injection via unsanitized query parameters. Attack requires prompt injection to control the base_url parameter. This issue has been fixed in version 0.4.85.

Server-Side Request Forgery in espocrm

EspoCRM is an Open Source CRM (Customer Relationship Management) software. In affected versions there is Server-Side Request Forgery (SSRF) vulnerability via the upload image from url api. Users who have access to `the /Attachment/fromImageUrl` endpoint can specify URL to point to an internal host. Even though there is check for content type, it can be bypassed by redirects in some cases. This SSRF can be leveraged to disclose internal information (in some cases), target internal hosts and bypass firewalls. This vulnerability has been addressed in commit `c536cee63` which is included in release version 8.0.5. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Discourse vulnerable to SSRF protection bypass possible with IPv4-mapped IPv6 addresses

Discourse is an open-source discussion platform. Prior to version 3.1.0.beta3 of the `beta` and `tests-passed` branches, attackers are able to bypass Discourse's server-side request forgery (SSRF) protection for private IPv4 addresses by using a IPv4-mapped IPv6 address. The issue is patched in the latest beta and tests-passed version of Discourse. version 3.1.0.beta3 of the `beta` and `tests-passed` branches. There are no known workarounds.

Docling-Graph: SSRF via Missing Internal IP Validation in URLInputHandler

Docling-Graph turns documents into validated Pydantic objects, then builds a directed knowledge graph with explicit semantic relationships. Prior to 1.5.1, the URLInputHandler class in docling_graph/core/input/handlers.py makes HTTP requests to user-supplied URLs without validating whether the target resolves to a private, loopback, or link-local IP address. The URLValidator only checks for a valid scheme and non-empty netloc, performing no IP-level validation. Additionally, requests.head() was called with allow_redirects=True, allowing an attacker to redirect requests to internal endpoints via an intermediary URL. An attacker who can control the --source CLI argument or PipelineConfig.source API parameter can trigger Server-Side Request Forgery (SSRF). This vulnerability is fixed in 1.5.1.

Affected versions of Atlassian Jira Service Management Server and Data Center allow authenticated remote attackers to access the content of internal network resources via a Server-Side Request Forgery (SSRF) vulnerability in the CSV importing feature of JSM Insight. When running in an environment like Amazon EC2, this flaw may be used to access to a metadata resource that provides access credentials and other potentially confidential information. The affected versions are before version 4.13.20, from version 4.14.0 before 4.20.8, and from version 4.21.0 before 4.22.2.

Decidim vulnerable to possible CSRF attack at questionnaire templates preview

Decidim is a participatory democracy framework. Starting in version 0.23.0 and prior to versions 0.27.5 and 0.28.0, the CSRF authenticity token check is disabled for the questionnaire templates preview. The issue does not imply a serious security thread as you need to have access also to the session cookie in order to see this resource. This URL does not allow modifying the resource but it may allow attackers to gain access to information which was not meant to be public. The issue is fixed in version 0.27.5 and 0.28.0. As a workaround, disable the templates functionality or remove all available templates.
