CVE-2025-69012: 
WordPress vulnerability analysis and mitigation

CVE-2025-69012 is a Missing Authorization vulnerability in the WordPress plugin Event Organiser by Stephen Harris, classified under CWE-862. It allows authenticated attackers with low privileges to exploit incorrectly configured access control security levels, affecting all versions from n/a through 3.12.8. The vulnerability was published on December 30, 2025, and carries a CVSS v3.1 base score of 4.3 (Medium) (Feedly, EUVD).

The root cause is a Missing Authorization flaw (CWE-862), meaning the plugin fails to properly verify whether a requesting user has the appropriate permissions before executing certain actions. An authenticated attacker with low-level privileges (e.g., a subscriber or contributor role) can send crafted network requests to trigger functionality that should be restricted to higher-privileged users. The attack vector is network-based, requires no user interaction, and has low attack complexity, making it straightforward to exploit once authenticated (Feedly).

Successful exploitation results in a limited integrity impact — an attacker can perform unauthorized actions within the Event Organiser plugin that should be restricted to higher-privileged users. There is no confidentiality or availability impact reported. The scope is unchanged, meaning the vulnerability does not allow an attacker to pivot beyond the affected component (Feedly).

The vulnerability requires low-privilege authentication (e.g., a registered WordPress user account) and has low attack complexity, making it relatively easy to exploit for any authenticated user on an affected site. The EPSS score is approximately 0.017% (0.000170), indicating a low probability of active exploitation in the near term. No public proof-of-concept code, exploit kits, in-the-wild exploitation, or CISA KEV catalog listing have been reported as of the time of writing (Feedly).

WordPress site administrators should update the Event Organiser plugin to a version beyond 3.12.8 as soon as a patched release is made available by the plugin author Stephen Harris. In the interim, consider restricting user registration on the WordPress site to limit the pool of potential attackers, or temporarily deactivating the plugin if it is not critical to site operations. Monitor the official WordPress plugin repository and the Patchstack advisory page for patch availability (Feedly, Patchstack).
