What is CVE-2026-54708?

FreePBX, an open-source IP PBX software, has a vulnerability in its backup module prior to versions 16.0.72 and 17.0.7. This security issue allows attackers who have authenticated access with sufficient permissions to execute arbitrary code on the server. The vulnerability arises from improper path sanitization in the backup restore functionality, which permits users to upload malicious PHP files directly to the web root directory, potentially compromising the security of the server. Users are encouraged to upgrade to the patched versions to mitigate this risk.

Affected Version(s)

security-reporting < 16.0.72 < 16.0.72

security-reporting < 17.0.7 < 17.0.7
