{"id":"CVE-2026-128018","summary":"FrankenPHP before 1.13.4 Pending Worker Request Denial of Service","details":"FrankenPHP before 1.13.4 contains a denial of service vulnerability in worker mode where frankenphp_handle_request() returns false without finishing the dequeued request after a fatal error during request startup. Attackers who trigger startup fatal errors against worker scripts that keep calling frankenphp_handle_request() can leave client requests hanging indefinitely while the worker continues running.","aliases":["GHSA-x6j6-qv7w-fq3c"],"modified":"2026-11-14T07:04:32.417222387Z","published":"2026-11-13T09:34:09.269Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-404"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128018.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/128xxx/CVE-2026-128018.json"},{"type":"FIX","url":"https://github.com/php/frankenphp/commit/185bfe578af854d29d7bdff3dd83b3b9dea3572b"},{"type":"ADVISORY","url":"https://github.com/php/frankenphp/security/advisories/GHSA-x6j6-qv7w-fq3c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-128018"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/frankenphp-before-1.13.4-pending-worker-request-denial-of-service"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/php/frankenphp","events":[{"introduced":"0"},{"fixed":"7f50be9d86261bf7cff9b051ab4fb572e95020ed"},{"fixed":"185bfe578af854d29d7bdff3dd83b3b9dea3572b"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"1.13.4"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"},{"source":"REFERENCES_COMMIT","range":[{"fixed":"185bfe578af854d29d7bdff3dd83b3b9dea3572b"}]}]}}],"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":{"vanir_signatures_modified":"2026-11-14T07:04:32Z","source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-128018.json","vanir_signatures":[{"target":{"file":"frankenphp.c","function":"PHP_FUNCTION"},"deprecated":false,"digest":{"length":1458,"function_hash":"128252392731838530890024512152042080058"},"id":"CVE-2026-128018-8912f03e","signature_type":"Function","signature_version":"v1","source":"https://github.com/php/frankenphp/commit/185bfe578af854d29d7bdff3dd83b3b9dea3572b"},{"id":"CVE-2026-128018-e609be76","signature_type":"Line","signature_version":"v1","source":"https://github.com/php/frankenphp/commit/185bfe578af854d29d7bdff3dd83b3b9dea3572b","target":{"file":"frankenphp.c"},"deprecated":false,"digest":{"line_hashes":["102081790753796892978593321155169629760","239757177678331160588390883427000646133","33379708922387848385859080593388841192","18543898512182257956765635853931870669","245930405389563212301735512118590373832"],"threshold":0.9}}]}}],"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"}]}
