{"id":"CVE-2026-128017","summary":"FrankenPHP before 1.13.4 Double Free in Worker Mode via Non-Form POST","details":"FrankenPHP before 1.13.4 contains a double free vulnerability in worker mode that frees SG(request_info).content_type_dup twice when a worker script ends its loop after a non-form POST request. Unauthenticated attackers can send repeated JSON POST requests until the worker loop ends, aborting the whole process when USE_ZEND_ALLOC=0 is set.","aliases":["GHSA-h764-4wh7-m7j2"],"modified":"2026-11-14T07:04:32.797204757Z","published":"2026-11-13T09:34:09.979Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-415"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128017.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128017.json"},{"type":"FIX","url":"https://github.com/php/frankenphp/commit/8777cc2e5c872ebb869fa2b5f972a913648621e8"},{"type":"ADVISORY","url":"https://github.com/php/frankenphp/security/advisories/GHSA-h764-4wh7-m7j2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-128017"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/frankenphp-before-1.13.4-double-free-in-worker-mode-via-non-form-post"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/php/frankenphp","events":[{"introduced":"0"},{"fixed":"7f50be9d86261bf7cff9b051ab4fb572e95020ed"},{"fixed":"8777cc2e5c872ebb869fa2b5f972a913648621e8"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"0"},{"fixed":"1.13.4"}]},{"range":[{"fixed":"8777cc2e5c872ebb869fa2b5f972a913648621e8"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["v1.13.3","caddy/v1.13.3","v1.13.2","caddy/v1.13.2","v1.13.0","caddy/v1.13.0","v1.13.1","caddy/v1.13.1","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-2026-128017.json","vanir_signatures":[{"deprecated":false,"digest":{"line_hashes":["190644492041911298716244649444726223995","107865272538848736543250759685558269661","116038648685517856945249286562899640506","312702436910486583176198684176587079785"],"threshold":0.9},"id":"CVE-2026-128017-0b869611","signature_type":"Line","signature_version":"v1","source":"https://github.com/php/frankenphp/commit/8777cc2e5c872ebb869fa2b5f972a913648621e8","target":{"file":"frankenphp.c"}},{"deprecated":false,"digest":{"length":622,"function_hash":"110437238805598726806836264462748027207"},"id":"CVE-2026-128017-6a367b1c","signature_type":"Function","signature_version":"v1","source":"https://github.com/php/frankenphp/commit/8777cc2e5c872ebb869fa2b5f972a913648621e8","target":{"function":"frankenphp_worker_request_shutdown","file":"frankenphp.c"}}],"vanir_signatures_modified":"2026-11-14T07:04:32Z"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
