CVE-2026-115871

WP STAGING <= 4.19.0 - Authenticated (Administrator+) Arbitrary Directory Deletion via 'deleteDir' Parameter

Low 2.7

Description

The WP STAGING – Backups & Restore, Migration & Clone Plugin – Cloud Backups, Scheduled Backups plugin for WordPress is vulnerable to Arbitrary Directory Deletion in all versions up to, and including, 4.19.0. This is due to insufficient path validation in the `cleanStagingDirectory` function, where the `deleteDir` parameter is only stripped of whitespace and double slashes by `sanitizePath()` without removing `..` traversal sequences or enforcing containment within the staging directory, leaving the sole pre-deletion guard as a simple string equality check against the WordPress home path. This makes it possible for authenticated attackers, with administrator-level access and above, to recursively delete arbitrary directories on the server — including `wp-content`, `wp-admin`, or directories outside the WordPress installation on shared hosting — resulting in denial of service or permanent data loss. An attacker must sequence a clone start, cancellation, and restart to drive the `delete_job` cache into the `directory` step before re-cancelling with a manipulated `deleteDir` value supplied via the `wp_ajax_wpstg_cancel_clone` endpoint.
