CVE-2025-62143: 
WordPress vulnerability analysis and mitigation

CVE-2025-62143 is a sensitive data exposure vulnerability (CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere) in the Post Video Players WordPress plugin (slug: video-playlist-and-gallery-plugin) developed by nicashmu. The vulnerability affects all versions through and including 1.163, allowing authenticated attackers with low privileges to retrieve embedded sensitive data. It was published on December 31, 2025, and assigned a CVSS v3.1 base score of 4.3 (Medium) by Patchstack (Patchstack, Red Hat CVE).

The vulnerability is classified as CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere), mapped to CAPEC-170 (Web Application Fingerprinting). The flaw allows an authenticated, low-privileged user to retrieve sensitive data embedded within the plugin's functionality over the network, requiring no user interaction and no elevated privileges beyond a basic authenticated session. The attack vector is network-based with low complexity, suggesting the plugin exposes sensitive system or configuration information through an insufficiently protected endpoint or API call accessible to any logged-in WordPress user (Patchstack, Red Hat CVE).

Successful exploitation results in a limited confidentiality breach — an authenticated attacker can retrieve sensitive system information embedded within the plugin, such as configuration data, API keys, or internal path details. There is no impact on integrity or availability. While the direct impact is low, exposed sensitive data could facilitate further attacks such as privilege escalation or targeted exploitation of other vulnerabilities on the same WordPress installation (Patchstack).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been identified for CVE-2025-62143. The EPSS score is approximately 0.027%, indicating a very low probability of exploitation in the near term. The vulnerability requires at least a low-privileged authenticated account on the target WordPress site, which limits opportunistic exploitation. It is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog (Red Hat CVE).

WordPress site administrators should update the Post Video Players plugin to a version beyond 1.163 if a patched release is available from the plugin author (nicashmu). If no patched version is yet available, the recommended workaround is to deactivate and remove the plugin until a fix is released. Access to the WordPress admin panel should be restricted to trusted users, and the principle of least privilege should be enforced to limit the pool of accounts that could exploit this vulnerability (Patchstack).
