CVE-2025-64258: 
WordPress vulnerability analysis and mitigation

CVE-2025-64258 is a Sensitive Data Exposure vulnerability in the WordPress plugin "Follow My Blog Post" by WPWeb (wpwebelite). Classified under CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere), it allows unauthenticated remote attackers to retrieve embedded sensitive data from affected WordPress installations. The vulnerability affects all versions of the plugin through 2.3.9, with version 2.4.0 introducing the fix. It was published on December 18, 2025, and carries a CVSS v3.1 base score of 7.5 (High) (Feedly, Patchstack).

The root cause is classified as CWE-497 — Exposure of Sensitive System Information to an Unauthorized Control Sphere — meaning the plugin inadvertently exposes sensitive system or configuration data in a context accessible to unauthorized parties. The attack vector is network-based, requires no authentication, no user interaction, and low attack complexity, making it trivially exploitable by any remote attacker. The exploitation technique aligns with CAPEC-170 (Web Application Fingerprinting), suggesting the exposed data may include configuration details, credentials, or other embedded sensitive information that could aid further attacks. No public proof-of-concept code has been identified at this time (Feedly, Patchstack).

Successful exploitation results in a high confidentiality impact with no effect on integrity or availability. An unauthenticated attacker can retrieve sensitive embedded data from the WordPress site, which may include API keys, credentials, or internal configuration details embedded within the plugin. This information could be leveraged for further attacks such as privilege escalation, lateral movement within the WordPress environment, or targeted phishing (Feedly).

No public exploit code or active in-the-wild exploitation has been reported for CVE-2025-64258 as of the available data. The EPSS score is approximately 0.018% (0.000180), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. However, the zero-authentication requirement and network accessibility make it a low-barrier target if exploitation details become public (Feedly).

The vendor (WPWeb/wpwebelite) has released version 2.4.0 of the Follow My Blog Post plugin, which addresses this vulnerability. WordPress site administrators should update the plugin to version 2.4.0 or later immediately via the WordPress admin dashboard or by downloading the updated plugin from the WordPress plugin repository. No configuration-based workaround is known; upgrading is the only recommended remediation (Feedly, Patchstack).
