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.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-943"],"vendors":[],"products":[],"references":[{"url":"https://github.com/discourse/discourse/commit/113c34d433d564bc69642649d501251a7e820b52","tags":[]},{"url":"https://github.com/discourse/discourse/commit/20c48bef712ee3edd4f7af58ca1123cb0c16ef6f","tags":[]},{"url":"https://github.com/discourse/discourse/commit/a04cab107a9f57939456181c4b082d0a34ec39bd","tags":[]},{"url":"https://github.com/discourse/discourse/commit/cb3ca8420fcc7aba334effd011cf41943a336fa6","tags":[]},{"url":"https://github.com/discourse/discourse/pull/42882","tags":[]},{"url":"https://github.com/discourse/discourse/security/advisories/GHSA-8hxh-573g-52gx","tags":[]}],"exploitRefs":[{"url":"https://github.com/discourse/discourse/commit/113c34d433d564bc69642649d501251a7e820b52","tags":[]},{"url":"https://github.com/discourse/discourse/commit/20c48bef712ee3edd4f7af58ca1123cb0c16ef6f","tags":[]},{"url":"https://github.com/discourse/discourse/commit/a04cab107a9f57939456181c4b082d0a34ec39bd","tags":[]},{"url":"https://github.com/discourse/discourse/commit/cb3ca8420fcc7aba334effd011cf41943a336fa6","tags":[]},{"url":"https://github.com/discourse/discourse/pull/42882","tags":[]},{"url":"https://github.com/discourse/discourse/security/advisories/GHSA-8hxh-573g-52gx","tags":[]}],"hasPoc":true,"ai":null}
