Vikunja veans before 2.7.1 Credential Leak via Repo-Controlled .veans.yml Server

Published Nov 8, 2026 CVSS 4.0 · 6 Medium EPSS < 1% KEV · Not listed
Description
Vikunja veans before 2.7.1 contains a credential exposure vulnerability that allows malicious repository authors to capture API tokens by specifying an attacker-controlled server in .veans.yml. When veans runs in an untrusted checkout, it sends VEANS_TOKEN as a Bearer token, or login passwords, TOTP codes and tokens, to that server, granting attackers the victim's Vikunja access.
