Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Kirby CMS (Packagist getkirby/cms) versions before 4.9.5 and versions from 5.0.0 before 5.5.2 are affected. Sites that have not disabled the REST API can have a PHP error triggered in the API, which returns the full filesystem path of the Kirby installation to any remote user, without authentication. The source says this could help an attacker guess the default content.salt or prepare more targeted attacks. Upgrade to Kirby 4.9.5, 5.5.2, or a later version.
