CVE-2025-62929: 
WordPress vulnerability analysis and mitigation

CVE-2025-62929 is a Missing Authorization (Broken Access Control) vulnerability in the PickPlugins Testimonial Slider WordPress plugin, affecting versions up to and including 2.0.15. It allows authenticated attackers with low-level privileges to exploit incorrectly configured access control security levels (CWE-862). The vulnerability was reported by Abu Hurayra on September 5, 2025, and published by Patchstack on October 5, 2025. It carries a CVSS v3.1 base score of 8.8 (High) per NVD, though Patchstack rates it at 6.5 (Patchstack).

The root cause is a missing authorization check (CWE-862) in one or more functions of the Testimonial Slider plugin, classified under OWASP Top 10 A1: Broken Access Control. An authenticated user with Contributor or Developer-level privileges can invoke higher-privileged actions that lack proper capability or nonce token verification. The attack is network-based, requires low privileges, and no user interaction, making it straightforward to exploit once an attacker has any authenticated foothold on the WordPress site (Patchstack).

Successful exploitation allows a low-privileged authenticated attacker to gain unauthorized access to sensitive information, modify or delete data, and potentially compromise the integrity and availability of the affected WordPress site. The high confidentiality, integrity, and availability impact scores indicate that an attacker could read protected content, alter site data, or disrupt site functionality. While lateral movement beyond the WordPress instance is not directly implied, unauthorized administrative actions could facilitate further compromise of the hosting environment (Patchstack).

As of the time of publication, there is no public proof-of-concept exploit and no evidence of active in-the-wild exploitation. The EPSS score is approximately 0.017%, indicating a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack notes that vulnerabilities of this class are sometimes used in mass-exploit campaigns targeting WordPress sites at scale (Patchstack).

The primary remediation is to update the Testimonial Slider plugin to a version beyond 2.0.15; as of the advisory publication, no official patched version was confirmed available, so administrators should monitor the WordPress plugin repository for an updated release. In the interim, consider deactivating the plugin until a patch is available, or contact your hosting provider for assistance. Additionally, review and enforce the principle of least privilege for WordPress user roles, and monitor for suspicious activity or unauthorized content changes (Patchstack).
