CVE-2025-58679: 
WordPress vulnerability analysis and mitigation

CVE-2025-58679 is a Missing Authorization vulnerability in the AppMySite WordPress plugin that allows unauthenticated attackers to exploit incorrectly configured access control security levels. It affects AppMySite plugin versions up to and including 3.15.0. The vulnerability was published on September 22, 2025, and carries a CVSS v3.1 base score of 5.3 (Medium) (Feedly).

The vulnerability is classified as CWE-862 (Missing Authorization), meaning the plugin fails to properly verify that a requesting user has the necessary permissions before performing sensitive operations. This allows network-based attackers with no authentication or privileges required to access restricted functionality or data. The attack complexity is low and requires no user interaction, making it straightforward to exploit remotely (Feedly).

Successful exploitation results in a low-level confidentiality impact, with no integrity or availability impact. Unauthenticated remote attackers may be able to access information or functionality that should be restricted to authorized users on WordPress sites running the affected AppMySite plugin. The scope is unchanged, limiting the impact to the vulnerable component itself (Feedly).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported for CVE-2025-58679. The EPSS score is approximately 0.037%, indicating a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, and no threat actor attribution has been identified (Feedly).

Users should update the AppMySite WordPress plugin to a version beyond 3.15.0 that addresses this missing authorization issue. Site administrators should monitor the official WordPress plugin repository or the AppMySite vendor for a patched release and apply it promptly. As a temporary measure, consider disabling the plugin until a fix is available if the site handles sensitive data (Feedly, Wordfence).

Wordfence included CVE-2025-58679 in its weekly WordPress vulnerability report for the period of September 22–28, 2025, noting it as a broken access control issue in the AppMySite plugin (Wordfence). No significant additional vendor statements or notable researcher commentary have been identified beyond standard vulnerability database listings.
