{"schema":"threatline.record/2","record":{"id":"CVE-2026-107334","aliases":["GHSA-jr6p-63pg-hr6g"],"summary":"Incorrect Authorization in Malcolm","details":"Malcolm's nginx Lua role-based access control (RBAC) layer decides whether an authenticated user may reach a role-restricted path (e.g. /htadmin, /auth, /admin_login, /arkime/api/esadmin, NetBox, upload endpoints) by pattern-matching the raw, percent-encoded request URI. Nginx itself, however, selects which location block actually serves the request using the percent-decoded, normalized URI. Because the RBAC check never percent-decodes its input, an authenticated low-privilege user can request an admin-only path using percent-encoding (e.g. /%68tadmin.php) and have nginx route it to the restricted location while the Lua RBAC gate evaluating the un-decoded raw string finds no matching restriction and grants access.","categories":["Unclassified"],"product":"Malcolm","vendor":"CISA","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-107334","source_modified_at":"2026-10-14T19:35:58.181Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Malcolm","vendor":"CISA","versions":[{"status":"affected","version":"0","lessThanOrEqual":"26.07.1","versionType":"custom"},{"status":"unaffected","version":"26.08.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":5.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00213,"percentile":0.11018,"score_date":"2026-10-23"},"published_at":"2026-10-08T17:32:00.480Z","modified_at":"2026-10-14T19:35:58.181Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-107334","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T19:35:58.181Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107334","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/cisagov/Malcolm/security/advisories/GHSA-jr6p-63pg-hr6g","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-280-01.json","tags":["government-resource"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-08T19:04:22.822418Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T19:35:58.181Z","content_hash":"5103f6c5935cd9e651abd27fcdeabcf46f20451456456e056c512310bf1f85f1"}}
