{"id":"CVE-2026-71518","summary":"Typemill \u003c 2.26.0 Authorization Bypass via Media File Download Route","details":"Typemill before 2.26.0 contains an authorization bypass vulnerability in the media file download route that allows unauthenticated attackers to access restricted files by submitting path-equivalent URL variants. Attackers can substitute normalized path forms such as dot-slash prefixes, double slashes, or percent-encoded sequences to pass role-based restriction checks while the filesystem resolves the request to the protected file, enabling unauthorized file download without credentials.","modified":"2026-09-18T03:30:37.211169378Z","published":"2026-08-17T21:05:10.836Z","database_specific":{"cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71518.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71518.json"},{"type":"ADVISORY","url":"https://github.com/typemill/typemill/releases/tag/v2.26.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71518"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/typemill-authorization-bypass-via-media-file-download-route"},{"type":"FIX","url":"https://github.com/typemill/typemill/commit/8c621063b4697a94342cb0a4b3905adda60e3d25"},{"type":"PACKAGE","url":"https://github.com/typemill/typemill"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/typemill/typemill","events":[{"introduced":"0"},{"fixed":"050cc875a3fcb9de5abc8da08b89895bdfea7865"},{"fixed":"8c621063b4697a94342cb0a4b3905adda60e3d25"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.26.0"}]}}],"versions":["v2.25.0","v2.24.2","v2.24.1","v2.24.0","v2.23.1","v2.23.0","v2.22.0","v2.21.3","v2.21.2","v2.21.1","v2.21.0","v2.20.2","v2.20.1","v2.20.0","v2.19.4","v2.19.3","v2.19.2","v2.19.1","v2.19.0","v2.18.4","v2.18.3","v2.18.2","v2.18.1","v2.18.0","v2.17.4","v2.17.1","v2.17.3","v2.17.2","v2.17.0","latest","2.16.2","2.16.1","2.16.0","2.15.0","2.6.0","1.1.6","1.1.5","1.1.4","1.1.3","1.1.2","1.1.1.0","1.1.1","1.1.01","1.1.0","1.0.3","1.0.2","1.0.1","1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-71518.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
