CVE-2025-64295 is a vulnerability identified in the All In One SEO Pack WordPress plugin, versions up to and including 4.8.6.1. The issue involves the insertion of sensitive information into data sent externally by the plugin, which can lead to unauthorized disclosure of embedded sensitive data. The vulnerability requires an attacker to have low-level privileges (PR:L) on the WordPress site but does not require user interaction (UI:N). The attack vector is network-based (AV:N), meaning exploitation can occur remotely over the network. The vulnerability impacts confidentiality (C:H) but does not affect integrity or availability. This suggests that sensitive data such as API keys, tokens, or user information might be embedded in outbound data streams, potentially exposing it to unauthorized parties. No known exploits have been reported in the wild, indicating that active exploitation is not currently observed, but the risk remains significant due to the nature of the data exposure. The vulnerability was reserved in late October 2025 and published in December 2025, with no patch links currently available, indicating that a fix may be forthcoming. The plugin is widely used in WordPress sites for SEO purposes, making the attack surface considerable. The vulnerability's requirement for low privileges means that even users with limited access could trigger the data leakage, increasing the risk in multi-user environments. The lack of required user interaction simplifies exploitation, and the network attack vector allows remote attackers to exploit the flaw without physical or local access. Overall, this vulnerability represents a moderate risk of sensitive data leakage through the SEO plugin's data handling mechanisms.

For European organizations, the primary impact of CVE-2025-64295 is the potential unauthorized disclosure of sensitive information embedded in data sent by the All In One SEO Pack plugin. This can lead to exposure of confidential business information, user credentials, API keys, or other sensitive data, which could be leveraged for further attacks such as account takeover, data breaches, or espionage. Organizations relying heavily on WordPress for their web presence, especially those using this SEO plugin, face increased risk. Data leakage could damage reputation, violate data protection regulations such as GDPR, and result in financial penalties. The vulnerability's exploitation requires low privileges, which means insider threats or compromised low-level accounts could trigger data exposure. The lack of impact on integrity or availability limits the threat to confidentiality, but the sensitivity of the leaked data could still have severe consequences. European sectors with high digital presence, including e-commerce, media, and public services, may be particularly vulnerable. The absence of known exploits in the wild provides a window for proactive mitigation before active attacks occur.

1. Monitor official channels for a security patch or update from Syed Balkhi and apply it immediately once available. 2. Until a patch is released, restrict user privileges to the minimum necessary, especially limiting access to users who can interact with the All In One SEO Pack plugin. 3. Conduct an audit of the data sent by the plugin to identify any sensitive information leakage and implement filtering or blocking mechanisms at the web application firewall (WAF) or network level. 4. Implement strict access controls and multi-factor authentication for all WordPress user accounts to reduce the risk of low-privilege account compromise. 5. Regularly review and monitor logs for unusual outbound data patterns or unexpected data transmissions from the web server hosting the plugin. 6. Consider temporarily disabling or replacing the All In One SEO Pack plugin with alternative SEO solutions if immediate patching is not feasible. 7. Educate site administrators and developers about the vulnerability and the importance of timely updates and privilege management. 8. Integrate vulnerability scanning tools that can detect the presence of vulnerable plugin versions in your environment.
