Technical details
A broken access control vulnerability exists in the Groundhogg plugin for WordPress due to missing authorization checks (CWE-862). The flaw allows an authenticated attacker with Subscriber-level privileges to execute functions or actions that should be restricted to higher-privileged users. The vulnerability is reachable over the network without user interaction, though it does require a valid low-level account. Successful exploitation allows the attacker to modify data or configurations (Integrity: High) but does not directly lead to data exfiltration or service downtime. The issue is resolved in version 4.4.1.
