CVE-2022-3291Network attack vector

Sensitive-data disclosure via unsafe License cache serialization

Published Oct 17, 2022 · Updated May 13, 2025

Sensitive-data exposure in GitLab EE 14.9 through 15.2.4, 15.3 through 15.3.3, and 15.4.0 allows remote authenticated users to read cache data. The License model enables JsonCache's unsafe_serialization_hash option, causing sensitive License attributes to be serialized into the shared cache. Low-privileged network access is required; the public record does not identify the cache retrieval path or exact fields exposed.
