RapiSafe public upload removal permits arbitrary file deletion

RapiSafe through 1.0.4 exposes RSMFCF7Vars.nonce to every visitor of a Contact Form 7 page containing its upload field. That public nonce reaches handleAjaxRemoveUpload(), which does not sufficiently constrain the supplied path. An unauthenticated visitor can therefore delete arbitrary server files, potentially leading to site compromise when a critical file is removed. The exact AJAX action, path parameter, and traversal encoding are not disclosed.

No fixed release is identified in the authoritative record. Update when a confirmed patch is available; until then, remove affected public upload fields or deactivate the plugin when warranted and inspect file integrity and access logs.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

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.

Source record

Technical description

The RapiSafe – Secure Multi File Upload for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the handleAjaxRemoveUpload function in all versions up to, and including, 1.0.4. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The nonce required to invoke the removal handler is exposed in public-facing JavaScript as RSMFCF7Vars.nonce on every Contact Form 7 page rendering a RapiSafe upload field, making it obtainable by any unauthenticated visitor.
