Unauthenticated form submission via CAPTCHA bypass

Published Jul 12, 2023 · Updated Nov 7, 2024

Improper CAPTCHA validation in JetBrains YouTrack before 2023.1.16597 allows remote attackers to submit Helpdesk forms without passing CAPTCHA. The Helpdesk form submission path accepts requests without properly validating CAPTCHA responses; JetBrains has not disclosed the responsible function or patch diff. Exposure requires a reachable Helpdesk online form with CAPTCHA enabled and permits automated unwanted ticket creation, with no reported ability to read existing data.
