CVE-2024-6530Public exploitNetwork attack vector

Stored XSS via unsanitized OAuth application name

Published Oct 10, 2024 · Updated Oct 10, 2024

Stored cross-site scripting in GitLab allows remote authenticated users to execute script when another user views an OAuth authorization page. The /oauth/authorize view renders the stored OAuth application name as HTML without sanitization. The attack requires application-creation access, a victim who opens its authorization URL, and a deployment where CSP does not block the payload; script runs in the victim's browser context.
