What is CVE-2026-44174?
CVE-2026-44174 is a high-severity code injection vulnerability in getkirby kirby, published on 16 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Kirby is an open-source content management system. Prior to 4.9.1 and 5.4.1, Kirby did not validate the model attributes that were used in its collection queries, allowing attackers to include arbitrary model methods in their queries. This includes methods with sensitive data such as password() (disclosing the password hash) or root() (disclosing the absolute filesystem path on the server) as well as methods that perform impactful actions such as loginPasswordless() (causing a privilege escalation to another user) or delete() (deleting all queried models in one go if the authenticated user has appropriate permissions). This issue has been fixed in versions 4.9.1 and 5.4.1.
Weakness: CWE-470
