CVE-2022-43411
First published: Wed Oct 19 2022(Updated: )
GitLab Plugin 1.5.35 and earlier does not use a constant-time comparison when checking whether the provided and expected webhook token are equal. This could potentially allow attackers to use statistical methods to obtain a valid webhook token. GitLab Plugin 1.5.36 uses a constant-time comparison when validating the webhook token.
