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.

 https://vulnerability.circl.lu/vuln/ghsa-p4h7-p9rj-2pq2 GHSA-p4h7-p9rj-2pq2 — Pheditor: Hardcoded default password 'admin' with no forced change enables full application compromise 2026-10-02T16:03:42.252545+00:00

Affected: Packagist: pheditor/pheditor

### Summary

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.

### Details

Tested repository: https://github.com/pheditor/pheditor

Tested commit: `e538f05b6faec99e5b23726bc9c17d6b57774297` (current HEAD on `main`)

Affected version: All versions of Pheditor

The password is hardcoded at `pheditor.php:11`:

```php define('PASSWORD', 'c7ad44cbad762a5da0a452f9e854fdc1e0e7a52a38015f23f3eab1d80b931dd472634dfac71cd34ebc35d16ab7fb8a90c81f975113d6c7538dc69dd8de9077ec'); ```

This is the SHA-512 hash of the string `admin`: ```bash echo -n 'admin' | sha512sum c7ad44cbad762a5da0a452f9e854fdc1e0e7a52a38015f23f3eab1d80b931dd472634dfac71cd34ebc35d16ab7fb8a90c81f975113d6c7538dc69dd8de9077ec ```

The application displays a warning banner at `pheditor.php:1956-1958` when the default password is in use, but this is only visual — there is no forced password change, no expiry, no lockout, and no setup wizard. Many deployments run with the default indefinitely.

The password hash is stored as unsalted SHA-512 in the source code. The password change feature (lines 363-391) writes the new hash directly into the PHP source file, meaning anyone with read access to the source can extract it.…
