CVE-2026-123499: Security vulnerability

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 VEANSTOKEN as a Bearer token, or login passwords, TOTP codes and tokens, to that server, granting attackers the victim's Vikunja access.
