The key is the request path and nothing else. Action roles that match on the method, content type, scheme or query make that resolution depend on state the key does not carry, so the memo answers for a request it was not built from.\n\nA path that resolves to no action is memoised as well, and replaying that entry returns without consulting any dispatch type, so no action is set and the request fails. A GET of a path whose action is declared POST-only therefore disables that path for every later request, the correct POST included. An entry that did resolve replays the level the earlier descent reached. Where a POST-only action sits below a shallower action on the same path, a GET memoises the shallow route, and a later POST is dispatched there with an auto() guarding the deeper controller never running.\n\nThe memo is cleared only when an action is registered, which happens at setup, so an entry lasts for the life of the process, and its cap of 2048 entries bounds how many paths one caller can disable. In the configuration measured, the misroute lands on the less privileged action, so it is an authorization check not running rather than a privilege gain.","state":0,"publishedAt":"2026-09-24T21:54:04.811+00:00","modifiedAt":"2026-09-25T16:35:28.629+00:00","affected":[{"ecosystem":"https://cpan.org/modules","name":"Catalyst-Seal","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"collectionURL\": \"https://cpan.org/modules\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"modules\": [\n                        \"Catalyst::Seal\"\n                    ],\n                    \"packageName\": \"Catalyst-Seal\",\n                    \"packageURL\": \"pkg:cpan/Catalyst-Seal\",\n                    \"programFiles\": [\n                        \"lib/Catalyst/Seal/Dispatch.pm\"\n                    ],\n                    \"programRoutines\": [\n                        {\n                            \"name\": \"Catalyst::Seal::Dispatch::_prepare_action\"\n                        }\n                    ],\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"0.03\",\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://metacpan.org/release/LNATION/Catalyst-Seal-0.02/source/lib/Catalyst/Seal/Dispatch.pm#L237-280","https://metacpan.org/release/LNATION/Catalyst-Seal-0.03/changes"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-85491","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-85491","identifiers":["CVE-2026-85491"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
