CVE-2025-39394 is a vulnerability identified in the Solid Plugins AnalyticsWP product, specifically affecting versions up to 2.1.2. The vulnerability is classified under CWE-497, which pertains to the Exposure of Sensitive System Information to an Unauthorized Control Sphere. This means that the plugin inadvertently allows unauthorized parties to retrieve embedded sensitive data from the system. The vulnerability does not require any authentication (PR:N) or user interaction (UI:N) and can be exploited remotely over the network (AV:N) with low attack complexity (AC:L). The impact is limited to confidentiality (C:L), with no effect on integrity or availability. The CVSS v3.1 base score is 5.3, indicating a medium severity level. Since the vulnerability exposes sensitive system information, it could potentially aid attackers in further reconnaissance or targeted attacks by revealing configuration details, credentials, or other sensitive embedded data within the AnalyticsWP plugin environment. However, there are no known exploits in the wild at this time, and no patches have been linked or published yet. The vulnerability was reserved in April 2025 and published in May 2025, indicating it is a recent discovery. Given that AnalyticsWP is a WordPress analytics plugin, the vulnerability primarily affects websites using this plugin for analytics purposes, potentially exposing sensitive data to unauthorized external entities.

For European organizations, the exposure of sensitive system information through AnalyticsWP could lead to increased risk of targeted attacks, especially for entities relying on this plugin for website analytics. The leakage of embedded sensitive data may include configuration details, API keys, or other credentials that could be leveraged by attackers to escalate privileges, conduct further reconnaissance, or compromise other systems. This can be particularly impactful for organizations handling personal data under GDPR, as unauthorized data exposure could lead to regulatory penalties and reputational damage. Additionally, organizations in sectors such as finance, healthcare, and government, which often use analytics tools to monitor web traffic and user behavior, may face heightened risks if attackers exploit this vulnerability to gain insights into system architecture or security controls. Although the vulnerability does not directly affect system integrity or availability, the confidentiality breach alone can facilitate subsequent attacks, making it a significant concern for European entities with public-facing websites using AnalyticsWP.

Given the absence of an official patch at the time of this report, European organizations should take proactive steps to mitigate the risk. First, conduct an immediate audit to identify all instances of AnalyticsWP plugin installations across their web properties. If possible, temporarily disable or remove the plugin until a security patch is released. Implement web application firewall (WAF) rules to monitor and block suspicious requests targeting the plugin endpoints that may attempt to retrieve sensitive data. Restrict access to analytics plugin data by IP whitelisting or other network segmentation techniques to limit exposure to trusted users only. Monitor web server logs for unusual access patterns or data exfiltration attempts related to AnalyticsWP. Additionally, organizations should subscribe to vendor notifications and security advisories from Solid Plugins to apply patches promptly once available. Finally, review and rotate any credentials or API keys that may have been exposed due to this vulnerability to minimize potential misuse.
