Prior to 3.0.0, the password change endpoint (POST /current/user/password) accepts a valid client token without requiring the account's current password or another elevated authentication step. An attacker who obtains a client token can set a new password for the associated user, taking control of password authentication and forcing account recovery through an administrator or direct database access. This issue is fixed in version 3.0.0.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-102603)\n\nAffected packages:\n\n- `github.com/gotify/server/v2 <= 2.9.1`\n- `github.com/gotify/server/v3 < 3.0.0`\n\nPatched in:\n\n- `github.com/gotify/server/v3 3.0.0`\n\nSource: https://github.com/advisories/GHSA-3hcj-9m7p-wwm9","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":221302,"id":"CVE-2026-102603","ts":1792031072237,"field":"cvss","old":null,"new":"5.3"},{"seq":221301,"id":"CVE-2026-102603","ts":1792031072237,"field":"severity","old":"none","new":"medium"}]}
