{"id":"CVE-2026-128025","summary":"FrankenPHP before 1.13.0 CGI Path-Split Boundary Bypass via splitPos","details":"FrankenPHP before 1.13.0 contains a path-split interpretation conflict in splitPos in cgi.go that allows unauthenticated attackers to execute protected PHP scripts by embedding .php inside a filename component. Attackers can request paths like /uploads/a.php.txt/b.php to execute uploads/a.php despite route-level or WAF deny rules and forge PATH_INFO, SCRIPT_NAME, and PHP_SELF values.","aliases":["GHSA-xxjp-cjxr-2x6m"],"modified":"2026-11-14T02:47:31.974391018Z","published":"2026-11-13T09:34:04.485Z","database_specific":{"cwe_ids":["CWE-436"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128025.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128025.json"},{"type":"ADVISORY","url":"https://github.com/php/frankenphp/security/advisories/GHSA-xxjp-cjxr-2x6m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-128025"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/frankenphp-before-1.13.0-cgi-path-split-boundary-bypass-via-splitpos"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/php/frankenphp","events":[{"introduced":"0"},{"fixed":"233f793654acf53be41385a4a29ac5e126cf6701"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"1.13.0"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]}}],"versions":["v1.12.7","caddy/v1.12.7","v1.12.6","caddy/v1.12.6","v1.12.5","caddy/v1.12.5","v1.12.4","caddy/v1.12.4","v1.12.3","caddy/v1.12.3","v1.12.2","caddy/v1.12.2","v1.12.1","caddy/v1.12.1","v1.12.0","caddy/v1.12.0","v1.11.3","caddy/v1.11.3","v1.11.2","caddy/v1.11.2","v1.11.1","caddy/v1.11.1","v1.11.0","caddy/v1.11.0","v1.10.1","caddy/v1.10.1","v1.10.0","caddy/v1.10.0","v1.9.1","caddy/v1.9.1","v1.9.0","caddy/v1.9.0","v1.8.0","caddy/v1.8.0","v1.7.0","caddy/v1.7.0","v1.6.2","caddy/v1.6.2","v1.6.1","caddy/v1.6.1","v1.6.0","caddy/v1.6.0","v1.5.0","caddy/v1.5.0","v1.4.4","caddy/v1.4.4","v1.4.3","caddy/v1.4.3","v1.4.2","caddy/v1.4.2","v1.4.1","caddy/v1.4.1","v1.4.0","caddy/v1.4.0","v1.3.6","caddy/v1.3.6","v1.3.5","caddy/v1.3.5","v1.3.4","caddy/v1.3.4","v1.3.3","caddy/v1.3.3","v1.3.2","caddy/v1.3.2","v1.3.1","caddy/v1.3.1","v1.3.0","caddy/v1.3.0","v1.2.5","caddy/v1.2.5","v1.2.4","caddy/v1.2.4","v1.2.3","caddy/v1.2.3","v1.2.2","caddy/v1.2.2","v1.2.1","caddy/v1.2.1","v1.2.0","caddy/v1.2.0","v1.1.5","caddy/v1.1.5","v1.1.4","caddy/v1.1.4","v1.1.3","caddy/v1.1.3","v1.1.2","caddy/v1.1.2","v1.1.1","caddy/v1.1.1","v1.1.0","caddy/v1.1.0","v1.0.3","caddy/v1.0.3","v1.0.2","caddy/v1.0.2","v1.0.1","caddy/v1.0.1","v1.0.0","caddy/v1.0.0","v1.0.0-rc.4","caddy/v1.0.0-rc.4","v1.0.0-rc.3","caddy/v1.0.0-rc.3","v1.0.0-rc.2","caddy/v1.0.0-rc.2","v1.0.0-beta.2","caddy/v1.0.0-beta.2","v1.0.0-beta.1","caddy/v1.0.0-beta.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-128025.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
