What is CVE-2026-31858?
CVE-2026-31858 is a high-severity SQL injection vulnerability in Craftcms Craft Cms, published on 11 Mar 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Craft is a content management system (CMS). The ElementSearchController::actionSearch() endpoint is missing the unset() protection that was added to ElementIndexesController in CVE-2026-25495. The exact same SQL injection vulnerability (including criteria[orderBy], the original advisory vector) works on this controller because the fix was never applied to it. Any authenticated control panel user (no admin required) can inject arbitrary SQL via criteria[where], criteria[orderBy], or other query properties, and extract the full database contents via boolean-based blind injection. Users should update to the patched 5.9.9 release to mitigate the issue.
Weakness: CWE-89
