PatchTheCVECVE-2026-72551: A remote code execution vulnerability in Apioo Fusio 8.8.3 allows authenticated users with the Developer role
CVE-2026-72551 is a high-severity flaw (CVSS 8.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
A remote code execution vulnerability in Apioo Fusio 8.8.3 allows authenticated users with the Developer role to execute arbitrary OS commands by exploiting a PHP-Sandbox allow-list bypass. The sandbox allow-list permits functions that transitively invoke system(), enabling a developer to escape the sandbox and gain OS command execution on the server. An attacker with a Developer-role account can achieve full server compromise.
Why this priority
- High severity
A fixed release or distro patch exists.
