A server-side request forgery issue has been discovered in GitLab EE affecting all versions starting from 16.8 prior to 17.1.7, from 17.2 prior to 17.2.5, and from 17.3 prior to 17.3.2. It was possible for an attacker to make requests to internal resources using a custom Maven Dependency Proxy URL
An issue has been discovered in GitLab EE/CE affecting all versions from 16.9.7 prior to 17.1.7, 17.2 prior to 17.2.5, and 17.3 prior to 17.3.2. An improper input validation error allows attacker to squat on accounts via linking arbitrary unclaimed provider identities when JWT authentication is configured.
An issue has been discovered discovered in GitLab EE/CE affecting all versions starting from 15.10 before 17.1.7, all versions starting from 17.2 before 17.2.5, all versions starting from 17.3 before 17.3.2 will disclose user password from repository mirror configuration.
An issue was discovered in GitLab-EE starting with version 13.3 before 17.1.7, 17.2 before 17.2.5, and 17.3 before 17.3.2 that would allow an attacker to modify an on-demand DAST scan without permissions and leak variables.
An issue has been discovered in GitLab EE affecting all versions starting from 12.9 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 has been discovered in GitLab EE affecting all versions starting from 11.2 before 17.1.7, all versions starting from 17.2 before 17.2.5, all versions starting from 17.3 before 17.3.2. It was possible for a guest to read the source code of a private project by using group templates.
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.
