CVE-2026-82837Network attack vector

Credential disclosure via unauthorized senddata endpoints

Published Sep 15, 2026 · Updated Sep 15, 2026

Improper authorization in GitLab CE/EE allows remote authenticated users to access sensitive credentials and tokens through internal endpoints. Workhorse senddata emitters fail to enforce authorization on internal data emission endpoints, allowing requests to obtain secrets without passing through the expected proxy. Authentication and unspecified conditions are required in 10.1.0 through 19.1.7, 19.2 through 19.2.5, and 19.3 through 19.3.1; only credential and token exposure is reported.
