CVE-2025-52719 is a vulnerability classified under CWE-497, which pertains to the Exposure of Sensitive System Information to an Unauthorized Control Sphere. This vulnerability affects the Metagauss ProfileGrid product, specifically versions up to and including 5.9.5.2. The issue allows an attacker with limited privileges (requiring low privileges but no user interaction) to remotely retrieve embedded sensitive data from the system. The vulnerability is exploitable over the network (AV:N) with low attack complexity (AC:L), requiring privileges (PR:L) but no user interaction (UI:N). The scope of the vulnerability is unchanged (S:U), meaning the impact is confined to the vulnerable component. The confidentiality impact is low (C:L), with no impact on integrity (I:N) or availability (A:N). Essentially, an attacker who has some level of authenticated access can extract sensitive information that should not be exposed, potentially including configuration details, credentials, or other embedded secrets within ProfileGrid. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on June 20, 2025, indicating it is a recent discovery. Given the nature of ProfileGrid as a user profile and membership management plugin (commonly used in web applications, especially WordPress environments), the exposure of sensitive information could facilitate further attacks such as privilege escalation or targeted exploitation of other vulnerabilities by revealing system internals or credentials.

For European organizations using Metagauss ProfileGrid, particularly those managing user memberships and profiles on web platforms, this vulnerability poses a risk of unauthorized disclosure of sensitive system information. Although the confidentiality impact is rated low, the exposure of embedded sensitive data can aid attackers in crafting more effective attacks, such as lateral movement, privilege escalation, or targeted phishing campaigns. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, could face compliance risks if sensitive data is leaked. Additionally, the exposure may undermine trust in the affected web services, potentially leading to reputational damage. Since exploitation requires some level of authenticated access, the threat is more significant in environments where user privilege management is weak or where attackers can obtain low-level credentials. The lack of impact on integrity and availability reduces the risk of direct service disruption but does not eliminate the risk of indirect consequences stemming from information disclosure.

1. Implement strict access controls and privilege management to ensure that only authorized users have access to ProfileGrid functionalities, minimizing the risk that low-privilege accounts can exploit this vulnerability. 2. Monitor and audit user activities within ProfileGrid to detect any unusual access patterns that might indicate attempts to retrieve sensitive information. 3. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting ProfileGrid endpoints that may attempt to exploit this vulnerability. 4. Segregate sensitive configuration and credential storage from the ProfileGrid plugin environment where possible, reducing the impact of any data exposure. 5. Regularly review and update authentication mechanisms to prevent unauthorized access, including enforcing strong password policies and multi-factor authentication for administrative accounts. 6. Stay informed for official patches or updates from Metagauss and apply them promptly once available. 7. Conduct internal penetration testing focusing on ProfileGrid to identify and remediate any additional weaknesses related to information exposure. 8. Limit the exposure of ProfileGrid interfaces to internal networks or VPNs where feasible, reducing the attack surface.
