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.","cvss_v4":{"vector":"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","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-269","CWE-384","CWE-613"],"references":["https://github.com/php/frankenphp/commit/24d6c991a7761b638190eb081deae258143e9735","https://github.com/php/frankenphp/releases/tag/v1.11.2","https://github.com/php/frankenphp/security/advisories/GHSA-r3xh-3r3w-47gp"],"products":["php:frankenphp"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-24894","score":0.00497,"percentile":0.42635,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-r3xh-3r3w-47gp","url":"https://osv.dev/vulnerability/GHSA-r3xh-3r3w-47gp","summary":"FrankenPHP leaks session data between requests in worker mode","modified":"2026-02-19T20:41:22.841084Z","packages":[{"ecosystem":"Go","name":"github.com/dunglas/frankenphp","purl":"pkg:golang/github.com/dunglas/frankenphp","ranges":["<1.11.2"],"fixed":["1.11.2"]}]},{"id":"GO-2026-4489","url":"https://osv.dev/vulnerability/GO-2026-4489","summary":"FrankenPHP leaks session data between requests in worker mode in github.com/dunglas/frankenphp","modified":"2026-02-19T20:41:22.841084Z","packages":[{"ecosystem":"Go","name":"github.com/dunglas/frankenphp","purl":"pkg:golang/github.com/dunglas/frankenphp","ranges":["<1.11.2"],"fixed":["1.11.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
