CVE-2026-1675: CWE-1188 Initialization of a Resource with an Insecure Default in brstefanovic Advanced Country Blocker
The Advanced Country Blocker plugin for WordPress is vulnerable to Authorization Bypass in all versions up to, and including, 2.3.1 due to the use of a predictable default value for the secret bypass key created during installation without requiring users to change it. This makes it possible for unauthenticated attackers to bypass the geolocation blocking mechanism by appending the key to any URL on sites where the administrator has not changed the default value.
AI Analysis
Technical Summary
CVE-2026-1675 describes an authorization bypass vulnerability in the Advanced Country Blocker WordPress plugin by brstefanovic. The issue arises because the plugin uses a predictable default secret bypass key created during installation, which administrators are not required to change. Attackers can exploit this by appending the default key to any URL, effectively bypassing the plugin's geolocation blocking mechanism. This affects all versions up to and including 2.3.1. The vulnerability is classified under CWE-1188 (Initialization of a Resource with an Insecure Default). The CVSS 3.1 score is 5.3, reflecting a medium impact primarily on integrity with no confidentiality or availability impact.
Potential Impact
An unauthenticated attacker can bypass the geolocation blocking controls implemented by the plugin, potentially allowing access to restricted content or functionality that the site owner intended to block based on geographic location. The impact is limited to integrity as the attacker can circumvent access restrictions but does not gain confidentiality or availability violations according to the CVSS vector.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, site administrators should change the default secret bypass key if the plugin provides an option to do so, or consider disabling the plugin if geolocation blocking is critical. Monitoring for plugin updates from the vendor is recommended to apply any forthcoming official fixes.
