{"id":"CVE-2026-49211","summary":"Symfony UX: Information exposure via unescaped LIKE wildcards in EntitySearchUtil","details":"Symfony UX is a JavaScript ecosystem for Symfony. From 2.2.0 until 2.36.0 and 3.1.0, Symfony\\UX\\Autocomplete\\Doctrine\\EntitySearchUtil::addSearchClause() builds the LIKE expression used by the autocomplete endpoint by wrapping the client-supplied query in %...% without escaping SQL LIKE wildcards (%, _, \\), allowing unauthenticated users to turn the public BaseEntityAutocompleteType endpoint into a broad matcher or blind boolean oracle against every column in default searchable_fields. This issue is fixed in versions 2.36.0 and 3.1.0.","aliases":["GHSA-946h-jp5c-8fvh"],"modified":"2026-07-19T03:47:20.027764560Z","published":"2026-07-17T16:14:29.271Z","database_specific":{"cwe_ids":["CWE-200"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49211.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/symfony/ux/releases/tag/v2.36.0"},{"type":"WEB","url":"https://github.com/symfony/ux/releases/tag/v3.1.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49211.json"},{"type":"ADVISORY","url":"https://github.com/symfony/ux/security/advisories/GHSA-946h-jp5c-8fvh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49211"},{"type":"FIX","url":"https://github.com/symfony/ux/commit/725ab3d40689c91ff19ad2d01940a30007769214"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/symfony/ux","events":[{"introduced":"3cef8e0d9557bbde60c3f1bfd2cbb1004af7fc9a"},{"introduced":"9b4622ea7cbb9b4223d292fc3f8e8d2352f967c0"},{"fixed":"4c883fdb0f0e7ea577f851bd457024f7e88788c9"},{"fixed":"5ccec9746faa28d79a87138042174c3853d5702b"},{"fixed":"725ab3d40689c91ff19ad2d01940a30007769214"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"3.0.0"},{"fixed":"3.1.0"},{"introduced":"2.2.0"},{"fixed":"2.36.0"}]}}],"versions":["v2.35.0","v3.0.0","v2.34.0","v2.33.0","v2.32.0","v2.31.0","v2.30.0","v2.29.2","v2.29.1","v2.29.0","v2.28.2","v2.28.1","v2.28.0","v2.27.0","v2.26.0","v2.26.1","v2.25.2","v2.25.1","v2.25.0","v2.24.0","v2.23.0","v2.22.1","v2.22.0","v2.21.0","v2.9.1","v2.20.0","v2.19.3","v2.19.2","v2.19.0","v2.19.1","v2.18.1","v2.18.0","v2.17.0","v2.16.0","v2.14.0","v2.15.0","v2.14.2","v2.14.1","v2.13.1","v2.13.3","v2.13.2","v2.13.0","v2.12.0","v2.11.1","v2.11.2","v2.11.0","v2.10.0","v2.8.1","v2.9.0","v2.8.0","v2.7.1","v2.7.0","v2.6.1","v2.6.0","v2.5.0","v2.4.0","v2.3.0","v2.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-49211.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
