Shared Files path traversal turns entry deletion into arbitrary file deletion
Shared Files before 1.7.67 and Shared Files Pro before 1.7.68 use a bypassable single-pass traversal filter on frontend file submissions. An unauthenticated attacker can store a path outside uploads; permanently deleting that entry later removes the referenced server file, including files such as wp-config.php, causing denial of service and possible site takeover.

Shared Files 1.7.67, Shared Files Pro 1.7.68- Published
- Aug 28, 2026
This CVE was published Aug 28, 2026 and is one of 13 known issues for this plugin.
Update, patch or deactivate.
Update Shared Files to 1.7.67 or later and Shared Files Pro to 1.7.68 or later. Review submitted paths, restore deleted files from a known-good backup and rotate secrets if wp-config.php or another sensitive file was affected.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The Shared Files WordPress plugin before 1.7.67, shared-files-pro WordPress plugin before 1.7.68 do not properly sanitize a file path taken from a frontend file submission and their single-pass traversal filter is bypassable, allowing unauthenticated users to store a path that points outside the uploads directory. When the corresponding file entry is later permanently deleted, an arbitrary file on the server (such as wp-config.php) is deleted, leading to denial of service and potential site takeover.
