Stored cross-site scripting via forged requests
Published Dec 30, 2025 · Updated Dec 30, 2025
Cross-site request forgery in Werner Joss WP-CalDav2ICS 1.3.4 and earlier allows remote attackers to store cross-site scripting payloads. Patchstack has not disclosed the affected request handler, parameter, or verification operation that accepts the forged state-changing request. Exploitation requires a privileged user to visit attacker-controlled content; the stored payload can then execute with a later viewer's browser privileges.
