CVE-2022-29422Network attack vector

Stored script execution via unneutralized countdown settings

Published May 6, 2022 · Updated Apr 28, 2026

Stored cross-site scripting in Adam Skaat Countdown & Clock 2.3.2 and earlier allows remote authenticated users to inject scripts through settings. The plugin stores countdown width, progress height, margin, and circle before-and-after parameters without adequate output neutralization before rendering them. Administrator-level access is required to supply the payload, and script execution occurs when another user views the affected countdown.
