CVE-2025-62153: 
WordPress vulnerability analysis and mitigation

CVE-2025-62153 is a Missing Authorization vulnerability in the Quick Interest Slider WordPress plugin by Graham, classified under CWE-862. It allows low-privileged, authenticated attackers to exploit incorrectly configured access control security levels, potentially gaining unauthorized access to sensitive functionality. All versions up to and including 3.1.5 are affected. The vulnerability was published on December 9, 2025, and assigned by Patchstack. It carries a CVSS v3.1 base score of 8.8 (High) (Feedly, ENISA EUVD).

The root cause is a Missing Authorization flaw (CWE-862), meaning the plugin fails to properly verify whether a requesting user has the appropriate permissions before executing sensitive operations. The attack vector is network-based, requires only low privileges (e.g., a subscriber-level WordPress account), and demands no user interaction, making it straightforward to exploit. An attacker can send crafted requests to plugin endpoints that lack proper capability checks, thereby bypassing intended access controls and performing actions reserved for higher-privileged roles (Feedly).

Successful exploitation can result in high impact to confidentiality, integrity, and availability of the affected WordPress installation. A low-privileged attacker could gain unauthorized access to sensitive plugin data, modify or delete critical configuration or content managed by the plugin, and potentially disrupt plugin functionality entirely. The network-accessible nature of the vulnerability and the absence of any user interaction requirement amplify the risk for publicly exposed WordPress sites (Feedly).

As of the disclosure date, there is no public proof-of-concept exploit and no evidence of active in-the-wild exploitation (Feedly). The EPSS score is approximately 0.017%, indicating a currently low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been reported.

The primary remediation is to update the Quick Interest Slider plugin to a version newer than 3.1.5. If an immediate update is not possible, the plugin should be temporarily disabled to eliminate the attack surface. Additionally, administrators should review WordPress user roles to ensure no unnecessary low-privilege accounts exist, audit plugin access logs for suspicious activity, and restrict access to the WordPress admin panel via IP allowlisting where feasible (Feedly).
