Pheditor: Hardcoded default password 'admin' with no forced change enables full application compromise
Pheditor is a single-file editor and file manager written in PHP. From version 2.0.1 to before version 2.0.6, Pheditor ships with a hardcoded default password admin (SHA-512 hash stored at pheditor.php:11). There is no mechanism to force a password change on first login. Any deployment using the default credentials grants an attacker full access to the file editor, file upload, and terminal features, enabling arbitrary file read/write and remote code execution. This issue has been patched in version 2.0.6.
Pheditor: Incomplete command sanitization in terminal feature allows RCE via pipe operator, backtick substitution, and newline injection
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 ver
Authenticated terminal command whitelist bypass in Pheditor
Pheditor is a single-file editor and file manager written in PHP. Prior to version 2.0.5, there is an authenticated terminal command whitelist bypass. The terminal feature checks whether the submitted command starts with one of the configured TERMINAL_COMMANDS values, then passes the full command string to shell_exec(). Shell command substitution such as $() is not blocked, so an authenticated user with the terminal permission can bypass a restricted command allowlist and execute arbitrary shell commands as the web server user. This issue has been patched in version 2.0.5.
Pheditor: OS Command Injection in terminal handler via unsanitized 'dir' parameter (CWE-78)
Pheditor is a single-file editor and file manager written in PHP. From version 2.0.1 to before version 2.0.4, an OS Command Injection vulnerability in the terminal action handler allows any authenticated user to execute arbitrary OS commands by injecting shell metacharacters into the 'dir' POST parameter, completely bypassing the TERMINAL_COMMANDS whitelist and achieving full Remote Code Execution with web server privileges. This issue has been patched in version 2.0.4.
Pheditor: Authentication Bypass in Forced Password-Change Flow via Unverified Current Password
## Summary
The forced password-change flow, triggered when the stored password is still the default (`admin`), does not verify that the password submitted by the client actually matches the current password. Any non-empty value in `pheditor_password` is enough to reach the password-change form, and submitting `pheditor_new_password` / `pheditor_confirm_password` in the same request is enough to set an arbitrary new password and obtain an authenticated session — without ever proving knowledge of the current password.
## Root Cause
`pheditor.php` line 163:
```php
if (PASSWORD == hash('sha512', 'admin')) { // still default — force change pro
Pheditor: Terminal command-allowlist bypass via argument injection leads to RCE — surviving vector after the metacharacter-sanitization fixes
### Summary
pheditor's terminal feature restricts callers to an allowlist of commands (`TERMINAL_COMMANDS`) and rejects shell metacharacters. The allowlist is enforced as a PREFIX match with no argument validation, and the allowlist includes binaries that grant arbitrary command execution through their own options (`find`, `git`, `php`, `tar`, `grep`). A caller can therefore run any command using only allowlisted binaries and no rejected metacharacter, escaping the allowlist restriction the terminal feature relies on.
