DescriptionCVE.org

Unauthenticated Cross Site Request Forgery (CSRF) in Slider by 10Web <= 1.2.62 versions.

Per the Patchstack advisory title, the CSRF primitive chains directly to arbitrary file deletion, which is reflected in the CVSS 3.1 score of 7.4 (High) with Scope Changed (S:C) and High Availability impact (A:H), indicating the destruction extends beyond the plugin itself to the broader WordPress installation or filesystem. …
