{"schema":"threatline.record/2","record":{"id":"CVE-2026-91133","aliases":["GHSA-8hxh-573g-52gx"],"summary":"Discourse: Escape LIKE metacharacters in upload paths to prevent disclosure","details":"Discourse is an open-source discussion platform. Prior to 2026.1.8, 2026.6.3, 2026.7.2, and 2026.8.0, authenticated users could supply unescaped SQL LIKE metacharacters to upload-resolution patterns, causing wildcard input to select unrelated upload records instead of matching a literal identifier. The affected upload metadata, URL-lookup, and cooked-video-placeholder paths could resolve uploads the user was not authorized to access. This allowed disclosure of restricted metadata, including original filenames and secure-upload paths, without modifying the upload records. This issue is fixed in versions 2026.1.8, 2026.6.3, 2026.7.2, and 2026.8.0.","categories":["Applications & CMS"],"product":"discourse","vendor":"discourse","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-91133","source_modified_at":"2026-09-24T17:12:50.099Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"discourse","vendor":"discourse","versions":[{"version":"< 2026.8.0","status":"affected"},{"version":">= 2026.7.0-latest, < 2026.7.2","status":"affected"},{"version":">= 2026.6.0-latest, < 2026.6.3","status":"affected"},{"version":">= 2026.1.0-latest, < 2026.1.8","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00285,"percentile":0.19996,"score_date":"2026-10-23"},"published_at":"2026-09-24T16:53:00.147Z","modified_at":"2026-09-24T17:12:50.099Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-91133","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-24T17:12:50.099Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-91133","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/discourse/discourse/security/advisories/GHSA-8hxh-573g-52gx","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/discourse/discourse/pull/42882","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/discourse/discourse/commit/113c34d433d564bc69642649d501251a7e820b52","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/discourse/discourse/commit/20c48bef712ee3edd4f7af58ca1123cb0c16ef6f","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/discourse/discourse/commit/a04cab107a9f57939456181c4b082d0a34ec39bd","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/discourse/discourse/commit/cb3ca8420fcc7aba334effd011cf41943a336fa6","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-24T17:12:40.098136Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-24T17:12:50.099Z","content_hash":"f9d712f4907b4c540fd7818b40cb1fd435fbba72056f1f9e35577af04eee9fd7"}}
