CVE-2025-58007 is a medium-severity vulnerability classified under CWE-497, which pertains to the Exposure of Sensitive System Information to an Unauthorized Control Sphere. This vulnerability affects the NerdPress Social Pug plugin, specifically all versions up to and including 1.35.1. The flaw allows an attacker with limited privileges (requires low privileges) but no user interaction to retrieve embedded sensitive data from the system. The vulnerability is remotely exploitable over the network (AV:N) with low attack complexity (AC:L), and does not require user interaction (UI:N). The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component without impacting other components. The confidentiality impact is low (C:L), indicating that some sensitive information can be exposed, but there is no impact on integrity or availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on September 22, 2025, and was reserved about a month earlier. The Social Pug plugin is commonly used in WordPress environments to facilitate social sharing functionality, and exposure of sensitive system information could aid attackers in further reconnaissance or targeted attacks against the affected WordPress sites.

For European organizations using the NerdPress Social Pug plugin, this vulnerability could lead to unauthorized disclosure of sensitive system information such as configuration details, API keys, or other embedded secrets. While the confidentiality impact is rated low, such information disclosure can be leveraged by attackers to escalate privileges, conduct phishing campaigns, or perform more sophisticated attacks against the organization’s web infrastructure. Organizations in sectors with strict data protection regulations (e.g., GDPR) may face compliance risks if sensitive data is exposed. Additionally, the vulnerability could undermine trust in public-facing websites, impacting brand reputation. Since WordPress is widely used across Europe, especially among small and medium enterprises, the exposure risk is non-negligible. However, the lack of known active exploitation and the requirement for some level of privilege reduce the immediate threat level.

1. Immediate mitigation should include auditing all WordPress installations for the presence of the Social Pug plugin and verifying the version in use. 2. Although no official patch links are available yet, organizations should monitor NerdPress and trusted vulnerability databases for updates or patches and apply them promptly once released. 3. Restrict access to WordPress administrative interfaces and plugin files using network-level controls such as IP whitelisting or VPN access to reduce the risk of unauthorized users gaining the required privileges. 4. Implement strict role-based access control (RBAC) within WordPress to ensure that only trusted users have the minimal necessary privileges to reduce the attack surface. 5. Conduct regular security audits and scans to detect any unusual access patterns or data exfiltration attempts related to the plugin. 6. Consider temporarily disabling or replacing the Social Pug plugin with alternative social sharing tools that do not have known vulnerabilities until a patch is available. 7. Review and rotate any potentially exposed credentials or embedded secrets that could be disclosed through this vulnerability.
