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.
