CVE-2025-62153 is a Missing Authorization vulnerability identified in the Graham Quick Interest Slider plugin, a tool commonly used to enhance user engagement on websites by allowing users to select interests via a slider interface. The vulnerability exists in versions up to and including 3.1.5 and stems from incorrectly configured access control security levels. Specifically, the plugin fails to properly verify whether a user has the necessary permissions before allowing certain actions, enabling attackers with low privileges (PR:L) to perform unauthorized operations remotely (AV:N) without requiring user interaction (UI:N). The vulnerability affects confidentiality, integrity, and availability (C:H/I:H/A:H), meaning attackers could potentially access sensitive data, modify content or settings, and disrupt service availability. The CVSS v3.1 base score is 8.8, indicating a high severity level. Although no exploits are currently known in the wild, the vulnerability's characteristics make it a prime candidate for exploitation once weaponized. The issue was reserved in early October 2025 and published in December 2025, with no patches currently linked, suggesting that organizations must monitor for updates or apply interim controls. The lack of proper authorization checks could allow attackers to escalate privileges or manipulate site behavior, posing significant risks especially for websites relying on this plugin for user interaction or marketing purposes.

For European organizations, the impact of CVE-2025-62153 can be substantial. Many businesses in Europe use WordPress and related plugins like Quick Interest Slider to enhance customer engagement on e-commerce, marketing, and content platforms. Exploitation could lead to unauthorized access to user data, manipulation of displayed content or user preferences, and potential service outages. This could result in reputational damage, regulatory penalties under GDPR due to data breaches, and financial losses from disrupted operations or lost customer trust. Organizations in sectors such as retail, media, and online services are particularly vulnerable. The broad impact on confidentiality, integrity, and availability means that both customer data and business-critical functions could be compromised. Additionally, the ease of remote exploitation without user interaction increases the likelihood of attacks, especially in environments where patching is delayed or access controls are weak.

Immediate mitigation steps include auditing and tightening access control configurations around the Quick Interest Slider plugin to ensure only authorized users can perform sensitive actions. Organizations should monitor for official patches or updates from Graham and apply them promptly once available. In the interim, disabling the plugin or restricting its usage to trusted internal networks can reduce exposure. Web application firewalls (WAFs) can be configured to detect and block suspicious requests targeting the plugin’s endpoints. Regular security assessments and penetration testing should be conducted to identify any unauthorized access attempts. Additionally, organizations should review user privilege assignments to minimize the number of users with elevated permissions. Logging and monitoring of plugin-related activities will help in early detection of exploitation attempts. Finally, maintaining up-to-date backups ensures recovery capability in case of successful attacks.
