Personal QR Message permits unauthenticated PHP uploads
Personal QR Message through 1.0 exposes an unauthenticated upload handler that does not restrict file types. An unauthenticated attacker can upload a PHP file into a directly reachable location and request it to execute code as the web-server account. The CNA record does not disclose the handler, upload field, destination path or resulting URL pattern.

This CVE was published Aug 03, 2026 and is one of 1 known issue for this plugin.
Update, patch or deactivate.
Update to a corrected Personal QR Message release after 1.0 when available. Until then, disable the upload handler or replace the plugin, remove unexpected executable files and investigate requests to its upload directory.
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.
