{"cve":"CVE-2026-81892","nvd":{"published":"2026-08-31T21:17:52.927","modified":"2026-09-09T21:09:13.080","status":"Deferred","description":"EasyAdmin is a fast and modern admin generator for Symfony applications. From 4.0.0 until 4.29.16 and 5.5.1, EasyAdmin serves all backend requests through a single dashboard route and, for custom actions (Action::linkToRoute() and MenuItem::linkToRoute()), swaps the executed controller based on the routeName query parameter on the kernel.controller event. The swap happens after Symfony's security firewall has already evaluated access_control against the original dashboard URL, and the routeName value was not validated. As a result, a path-based access_control rule protecting the target route was never evaluated, so a low-privilege backend user who can reach a single EasyAdmin URL and knows a target route's name can execute that route's controller, bypassing the path-based rule. Only path-based protections are bypassed. Routes whose controller enforces its own authorization with #[IsGranted] or denyAccessUnlessGranted() remain protected because those checks are recomputed against the swapped-in controller. This issue is fixed in versions 4.29.16 and 5.5.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-639","CWE-862","CWE-863"],"references":["https://github.com/EasyCorp/EasyAdminBundle/commit/03be45c6b7213c4c984a1d0542b7ec60359329f8","https://github.com/EasyCorp/EasyAdminBundle/commit/6228dfef598d81eeb0baa35625e50812f3c77699","https://github.com/EasyCorp/EasyAdminBundle/releases/tag/v4.29.16","https://github.com/EasyCorp/EasyAdminBundle/releases/tag/v5.5.1","https://github.com/EasyCorp/EasyAdminBundle/security/advisories/GHSA-g2fm-8hr4-j82h"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-81892","score":0.00448,"percentile":0.38946,"date":"2026-11-01"},"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).
