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.","published":"2026-07-17T16:14:29.271Z","modified":"2026-08-12T03:51:10.082303490Z","cvss":null,"epss":{"score":0.00305,"percentile":0.23295,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"symfony/ux-autocomplete","fixedVersion":"2.36.0"},{"ecosystem":"Packagist","name":"symfony/ux-autocomplete","fixedVersion":"3.1.0"}],"fix":{"url":"https://github.com/symfony/ux/commit/725ab3d40689c91ff19ad2d01940a30007769214","label":"symfony/ux@725ab3d"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:10.082303490Z"}}
