Detailsinfo

A vulnerability was found in Craft CMS 4.0.0-4.18.8/5.0.0-5.11.1. It has been classified as critical. This affects an unknown code block of the component Element Search. The manipulation of the argument attribute with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Craft CMS 4.0.0 before 4.18.9 and 5.0.0 before 5.11.2 contains an unauthenticated SQL injection vulnerability in the element search endpoint because the attribute parameter is concatenated into the query unsanitized and emulated PDO prepares allow stacked statements. Remote attackers can read and write the database, setting the admin flag or overwriting password hashes in the users table to gain administrator access.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-123488 since 11/06/2026. The exploitability is told to be easy.
