This critical-severity CVE scores 10.0 under NVD CVSS v3. EPSS exploit probability: 94.3%, top 0% 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).

Cacti provides an operational monitoring and fault management framework. A command injection vulnerability on the 1.3.x DEV branch allows any unauthenticated user to execute arbitrary command on the server when register_argc_argv option of PHP is On. In cmd_realtime.php line 119, the $poller_id used as part of the command execution is sourced from $_SERVER['argv'], which can be controlled by URL when register_argc_argv option of PHP is On. And this option is On by default in many environments such as the main PHP Docker image for PHP. Commit 53e8014d1f082034e0646edc6286cde3800c683d contains a patch for the issue, but this commit was reverted in commit 99633903cad0de5ace636249de16f77e57a3c8fc.
