Name of the Vulnerable Software and Affected Versions SWHKD version 1.1.5

Description The issue is related to a lack of proper access control in the SWHKD implementation of the Wayland display server protocol, specifically when handling files with the -c option. This can allow an attacker to perform arbitrary file-existence tests, potentially leading to unauthorized access to protected information.

Recommendations For SWHKD version 1.1.5, consider disabling the -c option as a temporary workaround until a patch is available. Restrict access to sensitive files and information to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
