Attackers can combine valid Basic-Auth credentials with an active admin PHPSESSID cookie to bypass authorization boundaries, as the WebDAV layer incorrectly inherits elevated privileges from an ambient web session rather than enforcing independent stateless authentication per RFC 4918.","state":0,"publishedAt":"2026-09-16T14:38:11.325+00:00","modifiedAt":"2026-10-01T15:21:55.595+00:00","affected":[{"ecosystem":"Vendor product","name":"FileRise","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"error311\",\n                    \"product\": \"FileRise\",\n                    \"packageURL\": \"pkg:github/error311/FileRise\",\n                    \"repo\": \"https://github.com/error311/FileRise\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"3.28.0\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.6,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","score":6.8,"severity":"MEDIUM"}],"references":["https://github.com/error311/FileRise/releases/tag/v3.28.0","https://www.vulncheck.com/advisories/filerise-privilege-escalation-via-webdav-session-inheritance"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92616","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92616","identifiers":["CVE-2026-92616"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
