What is CVE-2026-123489?

Craft CMS versions 4.0.0 to 4.18.8 and 5.0.0 to 5.11.1 exhibit a blind SQL injection vulnerability due to the unchecked handling of elementId parameters in the sandbox-exposed getNext() and getPrev() methods. By manipulating user input, authenticated control panel users can exploit this flaw, allowing them to execute conditional SQL queries against the database, thus potentially exposing sensitive information. This vulnerability underscores the importance of input validation and sanitization in web applications.
