What is CVE-2026-123488?

Craft CMS versions 4.0.0 to 4.18.8 and 5.0.0 to 5.11.1 contain an unauthenticated SQL injection vulnerability in the element search endpoint. This occurs when the attribute parameter is unsanitized and concatenated into the SQL query, which permits remote attackers to execute arbitrary SQL commands. This vulnerability may allow attackers to manipulate the database, potentially resulting in unauthorized database access, including altering user permissions or overwriting critical password hashes in the users table.

Affected Version(s)

cms 4.0.0 < 4.18.9

cms 5.0.0 < 5.11.2
