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 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.

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.

A Denial of Service (DoS) issue has been discovered in GitLab CE/EE affecting all versions prior to 17.1.6, 17.2 prior to 17.2.4, and 17.3 prior to 17.3.1. A denial of service could occur upon importing a maliciously crafted repository using the GitHub importer.

An issue was discovered in GitLab EE affecting all versions starting 17.0 to 17.1.6, 17.2 prior to 17.2.4, and 17.3 prior to 17.3.1 allows an attacker to execute arbitrary command in a victim's pipeline through prompt injection.

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.

An issue has been discovered in GitLab EE affecting all versions starting from 12.5 before 17.1.6, all versions starting from 17.2 before 17.2.4, all versions starting from 17.3 before 17.3.1. Under certain conditions it may be possible to bypass the IP restriction for groups through GraphQL allowing unauthorised users to perform some actions at the group level.

A Denial of Service (DoS) condition has been discovered in GitLab CE/EE affecting all versions starting with 15.9 before 17.0.6, 17.1 prior to 17.1.4, and 17.2 prior to 17.2.2. It is possible for an attacker to cause catastrophic backtracking while parsing results from Elasticsearch.

An issue has been discovered in GitLab CE/EE affecting all versions starting from 13.9 before 17.0.6, all versions starting from 17.1 before 17.1.4, all versions starting from 17.2 before 17.2.2. Under certain conditions, access tokens may have been logged when an API request was made in a specific manner.

Multiple Denial of Service (DoS) conditions has been discovered in GitLab CE/EE affecting all versions starting from 1.0 prior to 17.0.6, starting from 17.1 prior to 17.1.4, and starting from 17.2 prior to 17.2.2 which allowed an attacker to cause resource exhaustion via banzai pipeline.
