{"apiVersion":"1.0","identifier":"CVE-2026-72834","description":"filebrowser before 2.63.19 contains a permission bypass in the /api/resources endpoint. The checksum (?checksum=) branch of resourceGetHandler reads the entire file to compute a digest and returns it without performing a Perm.Download check (unlike the sibling raw, preview, and subtitle paths). As a result, an authenticated user provisioned with Perm.Download=false can obtain a content-hash oracle for any same-scope file (md5/sha1/sha256/sha512), enabling confirmation of known/guessed content, change detection, and offline brute-force of low-entropy files. This is an incomplete fix of CVE-2026-35606; it bypasses only the Download permission and does not defeat scope/path authorization.","publishedAt":"2026-08-14T12:16:46","lastModifiedAt":"2026-08-14T15:17:10","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72834","cvssScore":4.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","epssProbability":0.00228,"riskScore":0.44,"affectedProduct":"filebrowser","affectedVersions":"<2.63.19","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72834","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72834","en":"https://www.redsauce.net/en/cves/CVE-2026-72834","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72834","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72834","de":"https://www.redsauce.net/de/cves/CVE-2026-72834","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72834","el":"https://www.redsauce.net/el/cves/CVE-2026-72834"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72834"}}
