CVE-2026-31858

Craft is a content management system (CMS).

Published Mar 11, 2026CWE-89EPSS 0.48%

Overview

CVE-2026-31858 is a high-severity vulnerability. It was published on March 11, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
