CVE-2022-43412Network attack vector

Webhook token disclosure via timing discrepancy

Published Oct 19, 2022 · Updated May 8, 2025

Timing discrepancy in Jenkins Generic Webhook Trigger Plugin 1.84.1 and earlier allows remote attackers to recover webhook tokens. The token-validation path compares provided and expected webhook tokens with a non-constant-time operation, exposing measurable response-time differences. Repeated unauthenticated webhook requests and statistical analysis are required; a recovered token can authenticate webhook-trigger requests.
