- CVE-2026-87719Critical
GitLab EE contains a vulnerability that allows an authenticated user with Duo Chat access to obtain Advanced Search instance configurations and sensitive credentials. The attacker uses a specially crafted GraphQL subscription argument to bypass serialization and perform server object lookup.
- CVE-2026-85706CriticalActively exploited
GitLab CE/EE contains a vulnerability in the repository commits API caused by improper path confinement and missing authentication enforcement. Under certain conditions, an unauthenticated user could read arbitrary files from the GitLab server.
