CVE-2025-9958Network attack vector

Credential disclosure via unredacted GraphQL fields

Published Sep 26, 2025 · Updated Sep 26, 2025

Information disclosure in GitLab 14.10 through 18.2.6, 18.3 through 18.3.2, and 18.4.0 allows remote authenticated users to read registry passwords. The Maven virtual registry GraphQL resolver returns upstream username and password fields in plaintext instead of redacting them. Guest access to any project in the group is sufficient, and a public project grants implicit Guest access, exposing stored Maven credentials.
