SCA: security update for pheditor/pheditor (GHSA-wg4w-wr5q-6vjc)

high Tenable Cloud Security Plugin ID 444788

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Pheditor is a single-file editor and file manager written in PHP. From version 2.0.1 to before version
 2.0.6, the terminal feature in Pheditor uses an incomplete character blocklist to sanitize user-supplied
 commands before passing them to shell_exec(). After the fix for GHSA-9643-6xjp-vx57 (which added $ to the
 blocklist), the characters | (single pipe), ` (backtick), and the newline byte (0x0A) remain unblocked. An
 authenticated user with the terminal permission (enabled by default) can leverage any of these to bypass
 the TERMINAL_COMMANDS allowlist and execute arbitrary OS commands as the web server user. This issue has
 been patched in version 2.0.6. (CVE-2026-55578)

Solution

Update the pheditor/pheditor library and its related packages to version 2.0.6 or later.
