When an application uses (1) multiple session cookies (e.g., one for user pages and one for admin pages) and (2)  a session handler is set to `DatabaseHandler`, `MemcachedHandler`, or `RedisHandler`, then if an attacker gets one session cookie (e.g., one for user pages), they may be able to access pages that require another session cookie (e.g., for admin pages). This issue has been patched, please upgrade to version 4.2.11 or later. As a workaround, use only one session cookie.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-287"],"references":["https://github.com/codeigniter4/CodeIgniter4/commit/f9fb6574fbeb5a4aa63f7ea87296523e10db9328","https://github.com/codeigniter4/CodeIgniter4/security/advisories/GHSA-6cq5-8cj7-g558","https://github.com/codeigniter4/CodeIgniter4/commit/f9fb6574fbeb5a4aa63f7ea87296523e10db9328","https://github.com/codeigniter4/CodeIgniter4/security/advisories/GHSA-6cq5-8cj7-g558"],"products":["codeigniter:codeigniter"],"source":"nvd","synced_at":"2026-10-19T21:37:31.370122805+00:00"},"epss":{"cve":"CVE-2022-46170","score":0.00912,"percentile":0.60051,"date":"2026-10-31"},"kev":null,"osv":[],"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).
