CVE-2026-22466: 
WordPress vulnerability analysis and mitigation

CVE-2026-22466 is a Missing Authorization vulnerability in the WP MapIt WordPress plugin developed by Chandni Patel. It allows authenticated attackers with low privileges to exploit incorrectly configured access control security levels, potentially performing unauthorized actions. The vulnerability affects WP MapIt versions from n/a through 3.0.3. It was published on January 22, 2026, and carries a CVSS v3.1 base score of 4.3 (Medium), assigned by CISA-ADP (Feedly, Patchstack).

The root cause is classified as CWE-862 (Missing Authorization), meaning the plugin fails to properly verify whether a requesting user has the necessary permissions before executing certain actions. The attack vector is network-based, requires low privileges (authenticated user), low attack complexity, and no user interaction. An attacker with a basic WordPress account can send crafted requests to plugin endpoints that lack proper capability checks, bypassing intended access controls and performing restricted operations (Feedly, Patchstack).

Successful exploitation results in a limited integrity impact — an authenticated low-privileged attacker can perform unauthorized actions within the WP MapIt plugin, such as modifying map data or plugin settings that should be restricted to higher-privileged users. There is no confidentiality or availability impact based on the CVSS assessment. The scope is unchanged, meaning the impact is confined to the vulnerable component itself and does not facilitate direct lateral movement or significant data exposure (Feedly).

No public proof-of-concept exploit code or in-the-wild exploitation has been reported for CVE-2026-22466. The EPSS score is approximately 0.017%, indicating a very low probability of exploitation in the near term. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been identified (Feedly).

Users of the WP MapIt WordPress plugin should update to a version beyond 3.0.3 if a patched release is available from the plugin developer or the WordPress plugin repository. If no patch is yet available, site administrators should consider deactivating the plugin until a fix is released. Restricting user registration and limiting low-privileged user access to WordPress sites can reduce the attack surface in the interim (Patchstack).
