EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 1.5%, top 28% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
