An issue was discovered in GitLab CE/EE affecting all versions before 17.6.0 in which users were unaware that files uploaded to comments on confidential issues and epics of public projects could be accessed without authentication via a direct link to the uploaded file URL.
An issue has been discovered in GitLab CE/EE affecting all versions from 9.4 before 17.4.6, 17.5 before 17.5.4, and 17.6 before 17.6.2. An attacker could cause a denial of service with requests for diff files on a commit or merge request.
An issue was discovered in GitLab CE/EE affecting all versions starting from 11.0 prior to 17.4.6, starting from 17.5 prior to 17.5.4, and starting from 17.6 prior to 17.6.2, where sensitive information passed in GraphQL mutations may have been retained in GraphQL logs.
An issue has been discovered in GitLab CE/EE affecting all versions from 8.12 before 17.4.5, 17.5 before 17.5.3, and 17.6 before 17.6.1. This issue allows an attacker with access to a victim's Personal Access Token (PAT) to escalate privileges.
An issue was discovered in GitLab CE/EE affecting all versions starting from 8.16 prior to 17.2.9, starting from 17.3 prior to 17.3.5, and starting from 17.4 prior to 17.4.2, which allows deploy keys to push to an archived repository.
An issue has been discovered in GitLab EE/CE affecting all versions starting from 8.0 before 16.4. The product did not sufficiently warn about security implications of granting merge rights to protected branches.
An issue has been discovered in GitLab EE affecting all versions starting from 11.1 before 17.1.7, 17.2 before 17.2.5, and 17.3 before 17.3.2. Under certain conditions an open redirect vulnerability could allow for an account takeover by breaking the OAuth flow.
An issue was discovered in GitLab CE/EE affecting all versions starting from 8.14 prior to 17.1.7, starting from 17.2 prior to 17.2.5, and starting from 17.3 prior to 17.3.2, which allows an attacker to trigger a pipeline as an arbitrary user under certain circumstances.
The Ruby SAML library is for implementing the client side of a SAML authorization. Ruby-SAML in <= 12.2 and 1.13.0 <= 1.16.0 does not properly verify the signature of the SAML Response. An unauthenticated attacker with access to any signed saml document (by the IdP) can thus forge a SAML Response/Assertion with arbitrary contents. This would allow the attacker to log in as arbitrary user within the vulnerable system. This vulnerability is fixed in 1.17.0 and 1.12.3.
An issue was discovered in GitLab CE/EE affecting all versions starting from 8.2 prior to 17.1.6 starting from 17.2 prior to 17.2.4, and starting from 17.3 prior to 17.3.1, which allows an attacker to create a branch with the same name as a deleted tag.
