CVE-2025-57958 is a Missing Authorization vulnerability classified under CWE-862 affecting the WPXPO WowAddons plugin, specifically versions up to 1.0.17. This vulnerability arises from improperly configured access control mechanisms within the plugin, allowing unauthorized users to perform actions or access functionalities that should be restricted. The vulnerability does not require any privileges or user interaction to exploit, and it can be triggered remotely over the network (AV:N, PR:N, UI:N). The CVSS v3.1 base score is 5.3, indicating a medium severity level. The impact primarily affects the integrity of the system, as unauthorized modifications or actions could be performed, but confidentiality and availability are not directly impacted. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's presence in a WordPress plugin means it could be leveraged to manipulate website content or configurations, potentially leading to defacement, unauthorized content injection, or other integrity violations. Since the plugin is a third-party extension, the risk depends on its deployment scale and the sensitivity of the websites using it.

For European organizations, especially those relying on WordPress websites enhanced with the WPXPO WowAddons plugin, this vulnerability poses a risk to website integrity. Attackers exploiting this flaw could alter website content, inject malicious code, or perform unauthorized administrative actions, potentially damaging brand reputation and user trust. Although confidentiality and availability impacts are limited, integrity breaches can lead to misinformation, defacement, or indirect compromise through injected scripts. Organizations in sectors such as e-commerce, government, media, and education that use this plugin may face operational disruptions and compliance challenges, particularly under GDPR if personal data is indirectly affected by unauthorized changes. The medium severity score suggests that while the threat is not critical, it should be addressed promptly to prevent escalation or combined attacks.

1. Immediate audit of all WordPress sites using the WPXPO WowAddons plugin to identify affected versions (up to 1.0.17). 2. Apply any available patches or updates from the vendor as soon as they are released. In the absence of official patches, consider temporarily disabling the plugin or restricting access to its functionalities via web application firewalls (WAF) or access control rules. 3. Implement strict role-based access controls on WordPress admin accounts to minimize potential damage from exploitation. 4. Monitor website logs for unusual activities related to the plugin endpoints or unauthorized changes. 5. Employ security plugins that can detect unauthorized file changes or content modifications. 6. Conduct regular backups of website data and configurations to enable quick recovery if exploitation occurs. 7. Engage with the vendor or security community to track developments and exploit disclosures related to this vulnerability.
