CVE-2025-62071 identifies a missing authorization vulnerability in the Repuso Social proof testimonials and reviews plugin, versions up to and including 5.29. This plugin is commonly used to display social proof via testimonials and reviews on websites, often integrated into WordPress environments. The vulnerability arises because the plugin fails to properly enforce authorization checks on certain functions or API endpoints, allowing users with low-level privileges (PR:L) to access data or perform actions they should not be permitted to. The CVSS vector indicates the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), requiring only low privileges and no user interaction (UI:N). The impact is limited to confidentiality (C:L), with no effect on integrity or availability. Although no known exploits are currently reported in the wild, the exposure of testimonial or review data could lead to information leakage, reputational damage, or be leveraged in social engineering attacks. The lack of patches or official fixes at the time of publication necessitates proactive mitigation. The vulnerability is particularly relevant for organizations that rely on this plugin for customer engagement and social proof on their websites. Given the plugin’s integration with popular CMS platforms, the attack surface includes many web-facing systems. The vulnerability’s medium severity reflects the limited scope of impact but ease of exploitation and potential data exposure.

For European organizations, this vulnerability could lead to unauthorized disclosure of customer testimonials and review data, potentially exposing personal information or business-sensitive feedback. This may result in reputational harm, loss of customer trust, and could be leveraged in targeted phishing or social engineering campaigns. Organizations in sectors such as e-commerce, hospitality, and services that heavily rely on customer reviews for marketing and trust-building are particularly at risk. Although the vulnerability does not directly affect system integrity or availability, the confidentiality breach could have compliance implications under GDPR if personal data is involved. The ease of exploitation and remote attack vector increase the likelihood of opportunistic attacks, especially against websites with weak user privilege management. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability becomes widely known.

1. Immediately audit all instances of the Repuso Social proof testimonials and reviews plugin to identify affected versions (<= 5.29). 2. Restrict access to the plugin’s administrative and API interfaces to trusted users only, using role-based access controls and network-level restrictions such as IP whitelisting. 3. Monitor official Repuso channels and security advisories for patches or updates addressing CVE-2025-62071 and apply them promptly once available. 4. Implement web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting the plugin’s endpoints. 5. Conduct regular permission reviews to ensure users have the minimum necessary privileges, especially on CMS platforms. 6. Consider temporarily disabling the plugin if it is not critical to business operations until a patch is released. 7. Log and monitor access to testimonial and review data to detect anomalous activity that could indicate exploitation attempts. 8. Educate website administrators about the vulnerability and the importance of timely updates and access controls.
