CVE-2026-63092 Details
Description
kirby-modules through 5.5.7, fixed in commit 315417e, contains an information disclosure vulnerability that allows any authenticated Kirby Panel user to retrieve the full plaintext commercial license key by sending a GET request to the modules/activate dialog endpoint. The plugin's activate dialog handler in lib/areas.php returns the complete key via ModulesLicense::readKey() without performing an administrator check, as the dialog is gated only by the access.system permission which defaults to true for all non-admin roles, enabling attackers to use the disclosed key to activate the plugin on arbitrary third-party installations.
A vulnerability allowing information disclosure has been identified in Kirby Modules versions through 5.5.7. This issue allows any authenticated Kirby Panel user to obtain the full plaintext commercial license key by sending a GET request to the modules/activate dialog endpoint. The vulnerability arises because the activate dialog handler in lib/areas.php returns the complete license key via the ModulesLicense::readKey() method without verifying if the user is an administrator. The dialog access is only controlled by the access.system permission, which is enabled by default for all non-admin roles. As a result, attackers can use the disclosed license key to activate the plugin on any third-party installation.
Users can update to Kirby Modules version 5.5.8 or later, where this vulnerability has been fixed.
