CVE-2025-66082: 
WordPress vulnerability analysis and mitigation

CVE-2025-66082 is a Missing Authorization (Broken Access Control) vulnerability in the WpEvently WordPress plugin (slug: mage-eventpress) developed by Magepeople Inc. It affects all versions up to and including 5.0.4, allowing unauthenticated attackers to exploit incorrectly configured access control security levels. The vulnerability was reported on October 31, 2025, by researcher Que Thanh Tuan and publicly disclosed on November 21–30, 2025. It carries a CVSS v3.1 base score of 5.3 (Medium) (Patchstack).

The root cause is classified as CWE-862 (Missing Authorization), meaning one or more plugin functions lack proper authorization, authentication, or nonce token checks before executing privileged actions. This allows an unauthenticated network attacker to invoke restricted functionality — such as modifying event data or accessing protected resources — without any credentials. The attack vector is network-based, requires no user interaction, and has low attack complexity, making it straightforward to exploit remotely (Patchstack).

Successful exploitation results in a limited confidentiality impact (low), with no direct integrity or availability impact per the CVSS scoring. An unauthenticated attacker could access or trigger functionality intended for higher-privileged users within the WpEvently plugin, potentially exposing event-related data or performing unauthorized actions on affected WordPress sites. While the individual impact is limited, Patchstack notes that vulnerabilities of this class are commonly used in mass-exploit campaigns targeting thousands of WordPress sites simultaneously (Patchstack).

No public proof-of-concept exploit code or confirmed in-the-wild exploitation has been reported for CVE-2025-66082. The EPSS score is approximately 0.028% (0.000280), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack classifies its priority as Low, noting it is unlikely to be exploited in a targeted manner, though mass-exploit campaigns against WordPress plugins remain a general risk (Patchstack).

The vendor has released a patched version: WpEvently 5.0.5. All users running version 5.0.4 or earlier should update immediately via the WordPress plugin dashboard. No configuration-based workaround is documented; upgrading to 5.0.5 or later is the only recommended remediation. Patchstack users can enable auto-update for vulnerable plugins to automate this process (Patchstack).
