Prior to 1.11.2, when running FrankenPHP in worker mode, the $_SESSION superglobal is not correctly reset between requests. This allows a subsequent request processed by the same worker to access the $_SESSION data of the previous request (potentially belonging to a different user) before session_start() is called. This vulnerability is fixed in 1.11.2.","affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/php/frankenphp","events":[{"introduced":"0"},{"fixed":"3aa71fd4282f017b8a953332548b0bf89950119c"},{"fixed":"24d6c991a7761b638190eb081deae258143e9735"}],"database_specific":{"cpe":"cpe:2.3:a:php:frankenphp:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.11.2"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["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-2026-24894.json","vanir_signatures":[{"deprecated":false,"digest":{"line_hashes":["213265085187612044908135478460510098073","318746243554270848565658122322433113185","219291634423679632694241794026211757442","172321232573808798734701191819465615245"],"threshold":0.9},"id":"CVE-2026-24894-4ea80605","signature_type":"Line","signature_version":"v1","source":"https://github.com/php/frankenphp/commit/24d6c991a7761b638190eb081deae258143e9735","target":{"file":"frankenphp.c"}},{"deprecated":false,"digest":{"function_hash":"5831440278684089906089427861289650742","length":853},"id":"CVE-2026-24894-8440458c","signature_type":"Function","signature_version":"v1","source":"https://github.com/php/frankenphp/commit/24d6c991a7761b638190eb081deae258143e9735","target":{"file":"frankenphp.c","function":"frankenphp_reset_super_globals"}}],"vanir_signatures_modified":"2026-08-12T15:31:51Z"}}],"references":[{"type":"WEB","url":"https://github.com/php/frankenphp/releases/tag/v1.11.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24894.json"},{"type":"ADVISORY","url":"https://github.com/php/frankenphp/security/advisories/GHSA-r3xh-3r3w-47gp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24894"},{"type":"FIX","url":"https://github.com/php/frankenphp/commit/24d6c991a7761b638190eb081deae258143e9735"}],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-269","CWE-384","CWE-613"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24894.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
