CVE-2022-4462Public exploitNetwork attack vector

Webhook credential disclosure via unmasked API response

Published Mar 9, 2023 · Updated Feb 28, 2025

Affected GitLab releases allow remote authenticated users to read inherited Discord webhook URLs through a project integrations API response. The project-level GET /projects/:id/integrations/discord endpoint returns a group owner's inherited webhook value in the raw response instead of masking or omitting the secret. A project maintainer with an access token can retrieve the credential and use it to post unauthenticated content to the configured Discord channel.
