CVE-2025-62052 identifies a missing authorization vulnerability in the One Page Express Companion plugin developed by Horea Radu, affecting versions up to and including 1.6.43. This vulnerability arises because the plugin fails to properly verify whether a user has the necessary permissions before allowing certain actions, effectively permitting users with low privileges (PR:L) to perform operations they should not be authorized for. The vulnerability is exploitable remotely over the network (AV:N) without requiring user interaction (UI:N), but it does require the attacker to have some level of authenticated access, albeit low privilege. The impact is limited to confidentiality (C:L), with no direct effect on integrity or availability. This means an attacker could potentially access or disclose some sensitive information that should be restricted but cannot alter data or disrupt service. The CVSS v3.1 base score is 4.3, categorizing it as a medium severity issue. No patches or known exploits have been reported at the time of publication, indicating that the vulnerability is newly disclosed and may not yet be widely exploited. The plugin is commonly used in WordPress environments to enhance one-page website functionality, making it a relevant target for attackers seeking to leverage privilege escalation or unauthorized data access within compromised or low-privilege accounts.

For European organizations, the primary impact of CVE-2025-62052 is the potential unauthorized disclosure of sensitive information managed or displayed via the One Page Express Companion plugin. Although the vulnerability does not allow data modification or service disruption, unauthorized access to confidential data can lead to privacy violations, compliance issues (e.g., GDPR), and reputational damage. Organizations relying on this plugin for their WordPress sites may face increased risk of data leakage if attackers exploit this flaw. Since exploitation requires low-level authenticated access, the threat is more significant in environments where user accounts are not tightly controlled or where credential compromise is possible. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits after public disclosure. The impact is more pronounced for organizations handling sensitive customer or internal data through their web presence.

1. Monitor for official patches or updates from the plugin developer and apply them promptly once available. 2. Restrict access to the WordPress admin and plugin management interfaces to trusted users only, employing strong authentication mechanisms such as multi-factor authentication (MFA). 3. Conduct regular audits of user privileges to ensure that only necessary accounts have access to sensitive plugin functions. 4. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin endpoints. 5. Review and harden WordPress security configurations, including limiting plugin installation and execution rights. 6. Monitor logs for unusual activity related to the plugin, such as unauthorized access attempts or privilege escalations. 7. Educate administrators and users about the risks of credential compromise and enforce strong password policies. 8. Consider isolating or disabling the plugin if it is not essential to reduce the attack surface until a patch is available.
