Admin-level command execution via unsigned plugin upload
Published Aug 10, 2026 · Updated Aug 10, 2026
Code injection in SaiAdmin 5.0.1 and earlier allows remote authenticated users to execute commands through a malicious plugin package. InstallLogic extracts an unsigned ZIP without filtering PHP files, copies them into Webman's plugin directory, and the task runner instantiates an attacker-named class without a whitelist. An administrator JWT is required; successful exploitation runs arbitrary commands with the SaiAdmin service account's privileges.
