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.","state":0,"publishedAt":"2026-09-24T16:53:00.147+00:00","modifiedAt":"2026-09-24T17:12:50.099+00:00","affected":[{"ecosystem":"Vendor product","name":"discourse","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"discourse\",\n                    \"product\": \"discourse\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2026.8.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2026.7.0-latest, < 2026.7.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2026.6.0-latest, < 2026.6.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2026.1.0-latest, < 2026.1.8\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/discourse/discourse/security/advisories/GHSA-8hxh-573g-52gx","https://github.com/discourse/discourse/pull/42882","https://github.com/discourse/discourse/commit/113c34d433d564bc69642649d501251a7e820b52","https://github.com/discourse/discourse/commit/20c48bef712ee3edd4f7af58ca1123cb0c16ef6f","https://github.com/discourse/discourse/commit/a04cab107a9f57939456181c4b082d0a34ec39bd","https://github.com/discourse/discourse/commit/cb3ca8420fcc7aba334effd011cf41943a336fa6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-91133","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-91133","identifiers":["CVE-2026-91133"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
