The VR-Frases (collect & share quotes) plugin for WordPress is vulnerable to reflected cross-site scripting (XSS) via several parameters in all versions up to, and including, 3.0.1 due to insufficient input sanitization and output escaping. This vulnerability allows unauthenticated attackers to inject arbitrary web scripts into pages, which may execute if they can successfully trick a user into performing an action such as clicking on a link. The vulnerability is classified as medium severity with a CVSS score of 6.1.
Risk to organizations includes the potential for unauthorized access to sensitive information, as attackers may exploit this vulnerability to execute malicious scripts within the context of the user's session. Given that user interaction is required to trigger the vulnerability, the threat level increases with the number of users interacting with the affected plugin. Organizations should prioritize patching immediately.
As of now, there are no known public exploits or proof of concepts available for this vulnerability. However, the lack of widespread public knowledge does not negate the potential for exploitation. Organizations using the VR-Frases plugin should take this vulnerability seriously and ensure they are running versions that contain the necessary patches.
Prompt action is essential for mitigating risks associated with this vulnerability. Organizations should address this issue in their priority patch cycle to avoid potential exploitation by malicious actors.
Vulnerability Details
The CVE-2025-0860 vulnerability allows for reflected cross-site scripting through multiple parameters, making it susceptible to XSS attacks. The CVSS 3.1 details reveal an attack vector of NETWORK, low attack complexity, no privileges required, and user interaction is necessary. The confidentiality and integrity impacts are rated low, while availability impact is none.
Technical Analysis
The root cause of this vulnerability stems from insufficient input sanitization and output escaping within the plugin's code. Attackers can exploit this by crafting malicious links that, when clicked by a user, execute arbitrary scripts on their browser. This vulnerability requires user interaction for exploitation, making it a lower risk than some remote code execution vulnerabilities but still serious.
Risk & Impact Analysis
The potential blast radius of this vulnerability includes all users who interact with the VR-Frases plugin. If exploited, attackers could gain unauthorized access to user sessions or perform actions on behalf of users without their consent. Organizations must assess the risk based on the number of users and the sensitivity of data handled by the plugin. Given the CVSS score of 6.1 and the associated risks, organizations should address this vulnerability in their priority patch cycle.
