Event deletion via unchecked front-end request
Published Feb 21, 2022 · Updated Apr 28, 2026
CSRF in Spiffy Plugins Spiffy Calendar 4.9.0 and earlier allows remote attackers to delete events through an administrator's browser. The front-end delete path processes a deletion action without validating request integrity, allowing a forged request to ride the active session. An authenticated administrator or another user permitted to manage events must visit attacker-controlled content; the consequence is deletion of calendar data.
