Gitlab · Gitlab Ce/Ee · CVE-2023-1965
**Name of the Vulnerable Software and Affected Versions**
GitLab EE versions 14.2 through 15.9.5
GitLab EE versions 15.10 through 15.10.4
GitLab EE versions 15.11 through 15.11.0
**Description**
An issue has been discovered in GitLab EE, where a lack of verification on the `RelayState` parameter allowed a maliciously crafted URL to obtain access tokens granted for 3rd party Group SAML SSO logins. This feature is not enabled by default.
**Recommendations**
For GitLab EE versions 14.2 through 15.9.5, update to version 15.9.6 or later.
For GitLab EE versions 15.10 through 15.10.4, update to version 15.10.5 or later.
For GitLab EE versions 15.11 through 15.11.0, update to version 15.11.1 or later.
As a temporary workaround, consider restricting access to the `RelayState` parameter to minimize the risk of exploitation.
