pmwiki.php in PmWiki 2.1 beta 20, with register_globals enabled, allows remote attackers to bypass protection mechanisms that deregister global variables by setting both a GPC variable and a GLOBALS[] variable with the same name, which causes PmWiki to unset the GLOBALS[] variable but not the GPC variable, which creates resultant vulnerabilities such as remote file inclusion and cross-site scripting (XSS).
Conclusion & alert: CVE-2006-0479 is rated High Exploit Risk (64.1/100): CVSS Medium severity, with medium exploitation likelihood (EPSS 3.11%). Core evidence: 1 public exploit reference(s) are indexed (Exploit-DB). EPSS rose +1.78% over the last day, indicating growing attacker interest. Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
