GitLab has remediated an issue in GitLab CE/EE affecting all versions from 16.2 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain deployment configurations, could have allowed an authenticated user to poison cached page content served to other users due to improper cache key construction.

Weakness

The product, when processing trusted data, accepts any untrusted data that is also included with the trusted data, treating the untrusted data as if it were trusted.
