An issue has been discovered in GitLab CE/EE affecting all versions from 15.10 before 18.0.5, 18.1 before 18.1.3, and 18.2 before 18.2.1 that, under specific circumstances, could have potentially allowed a successful attacker to trigger unintended content rendering leading to XSS.

An issue was discovered in GitLab Community and Enterprise Edition before 11.6.10, 11.7.x before 11.7.6, and 11.8.x before 11.8.1. It allows Information Exposure (issue 4 of 5).

A vulnerability was discovered in GitLab runner versions before 13.1.3, 13.2.3 and 13.3.1. It was possible to make the gitlab-runner process crash by sending malformed queries, resulting in a denial of service.

An information exposure vulnerability exists in gitlab.com <v12.3.2, <v12.2.6, and <v12.1.10 when using the blocking merge request feature, it was possible for an unauthenticated user to see the head pipeline data of a public project even though pipeline visibility was restricted.

A vulnerability was discovered in GitLab versions before 13.1.10, 13.2.8 and 13.3.4. GitLab Omniauth endpoint allowed a malicious user to submit content to be displayed back to the user within error messages.

An issue has been discovered in GitLab EE affecting all versions starting from 12.0 before 15.10.8, all versions starting from 15.11 before 15.11.7, all versions starting from 16.0 before 16.0.2. An attacker can clone a repository from a public project, from a disallowed IP, even after the top-level group has enabled IP restrictions on the group.

GitLab has remediated an issue in GitLab EE affecting all versions from 18.4 before 18.4.4, and 18.5 before 18.5.2 that could have allowed an authenticated user to gain CSRF tokens by exploiting improper input validation in repository references combined with redirect handling weaknesses.

An issue has been discovered in GitLab affecting all versions starting from 10.0 before 12.9.8, all versions starting from 12.10 before 12.10.7, all versions starting from 13.0 before 13.0.1. A user could use an unverified email as a public email and commit email by sending a specifically crafted request on user update settings.

An issue has been discovered in GitLab EE affecting all versions starting from 15.10 prior to 17.2.9, from 17.3 prior to 17.3.5, and from 17.4 prior to 17.4.2. Instances with Product Analytics Dashboard configured and enabled could be vulnerable to SSRF attacks.

An issue has been discovered in GitLab CE/EE affecting all versions starting from 11.0 before 14.3.6, all versions starting from 14.4 before 14.4.4, all versions starting from 14.5 before 14.5.2. A permissions validation flaw allowed group members with a developer role to elevate their privilege to a maintainer on projects they import

An issue has been discovered in GitLab affecting all versions starting from 12.10 before 14.4.5, all versions starting from 14.5.0 before 14.5.3, all versions starting from 14.6.0 before 14.6.2. GitLab was not correctly handling requests to delete existing packages which could result in a Denial of Service under specific conditions.

An issue has been discovered in GitLab CE/EE affecting all versions starting from 13.2. When querying the repository branches through API, GitLab was ignoring a query parameter and returning a considerable amount of results.

An issue has been discovered in GitLab affecting all versions starting from 7.7 before 14.4.5, all versions starting from 14.5.0 before 14.5.3, all versions starting from 14.6.0 before 14.6.2. GitLab was vulnerable to a Cross-Site Request Forgery attack that allows a malicious user to have their GitHub project imported on another GitLab user account.

An issue was discovered in GitLab Community and Enterprise Edition 8.14 through 12.2.1. The Jira integration contains a SSRF vulnerability as a result of a bypass of the current protection mechanisms against this type of attack, which would allow sending requests to any resources accessible in the local network by the GitLab server.

A confusion between tag and branch names in GitLab CE/EE affecting all versions since 13.7 allowed a Developer to access protected CI variables which should only be accessible to Maintainers

An issue was discovered in GitLab CE/EE affecting all versions starting from 16.0 prior to 17.3.7, starting from 17.4 prior to 17.4.4, and starting from 17.5 prior to 17.5.2, which could have allowed unauthorized access to the Kubernetes agent in a cluster under specific configurations.

An issue has been discovered in GitLab CE/EE affecting all versions starting from 14.3 before 15.6.7, all versions starting from 15.7 before 15.7.6, all versions starting from 15.8 before 15.8.1. An attacker may upload a crafted CI job artifact zip file in a project that uses dynamic child pipelines and make a sidekiq job allocate a lot of memory. In GitLab instances where Sidekiq is memory-limited, this may cause Denial of Service.

An issue has been discovered in GitLab affecting all versions starting from 13.11 before 15.8.5, all versions starting from 15.9 before 15.9.4, all versions starting from 15.10 before 15.10.1. It was possible that a project member demoted to a user role to read project updates by doing a diff with a pre-existing fork.

An improper authorization issue in GitLab CE/EE affecting all versions from 13.7 prior to 14.10.5, 15.0 prior to 15.0.4, and 15.1 prior to 15.1.1 allows an attacker to extract the value of an unprotected variable they know the name of in public projects or private projects they're a member of.
