Administrative data modification via nonce-less AJAX actions
Published May 30, 2024 · Updated Apr 8, 2026
CSRF in AJAX actions in comparisonslider Comparison Slider 1.0.5 and earlier allows remote attackers to alter slider data through forged requests. Several AJAX action handlers omit or incorrectly perform WordPress nonce validation before changing titles, deleting sliders, or updating plugin settings. Exploitation requires an authenticated site administrator to act on a crafted link or equivalent request, and the resulting changes are limited to plugin-managed data and settings.
