CVE-2024-27476Public exploitNetwork attack vector

Credential theft via unneutralized ticket links

Published Apr 10, 2024 · Updated Aug 2, 2024

HTML injection in Leantime 3.0.6 allows remote attackers to place malicious links in new tickets through the ticket creation interface. The ticket workflow accepts attacker-supplied anchor or href markup and renders the stored content without neutralizing HTML. A victim must follow the rendered link, which can redirect the browser to an attacker-controlled login page for credential theft.
