CVE-2025-67581: 
WordPress vulnerability analysis and mitigation

CVE-2025-67581 is a Missing Authorization vulnerability in the TrueBooker (truebooker-appointment-booking) WordPress plugin developed by themetechmount. It allows unauthenticated remote attackers to exploit incorrectly configured access control security levels. All versions through 1.1.0 are affected. The vulnerability was published on December 9, 2025, with assignment credited to Patchstack. It carries a CVSS v3.1 base score of 5.3 (Medium) (Feedly, EUVD).

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 no authentication, no user interaction, and low attack complexity, making it trivially exploitable by any remote actor. The specific functionality lacking authorization checks has not been publicly detailed in available sources, but the vulnerability class typically involves REST API endpoints or AJAX handlers in WordPress plugins that perform sensitive operations without capability checks (Feedly, EUVD).

Successful exploitation results in a low-level confidentiality impact with no integrity or availability impact, as reflected in the CVSS score. An unauthenticated attacker could access restricted information or functionality within the TrueBooker appointment booking plugin that should require elevated privileges. The scope is limited to the affected plugin's data and functionality, with no evidence of lateral movement potential or broader system compromise based on available information (Feedly).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported for CVE-2025-67581. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. The EPSS score is approximately 0.04%, indicating a very low probability of exploitation in the near term. No threat actor attribution has been identified (Feedly).

Users of the TrueBooker WordPress plugin should update to a version beyond 1.1.0 if a patched release is available from the plugin developer (themetechmount). If no patch is yet available, site administrators should consider deactivating or removing the plugin until a fix is released. Restricting access to WordPress REST API or AJAX endpoints via a web application firewall (WAF) may provide additional mitigation. Monitor the WordPress plugin repository and the vendor's communications for patch announcements (Feedly, EUVD).
