CVE-2025-0311 is a stored cross-site scripting vulnerability identified in the Orbit Fox by ThemeIsle plugin for WordPress, specifically within the Pricing Table widget component. The vulnerability arises from insufficient sanitization and escaping of user-supplied input attributes, which allows an attacker with contributor-level or higher privileges to inject arbitrary JavaScript code into pages generated by the plugin. Because the injected scripts are stored persistently, they execute every time a user accesses the affected page, potentially compromising user sessions, stealing cookies, or performing unauthorized actions on behalf of users. The vulnerability affects all versions up to and including 2.10.43. The CVSS 3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and privileges required at the contributor level. The scope is changed (S:C) indicating that the vulnerability affects resources beyond the initially vulnerable component. No user interaction is required for exploitation once the malicious script is injected. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the commonality of contributor-level access in WordPress sites and the widespread use of the plugin. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the need for immediate mitigation.

The impact of CVE-2025-0311 is primarily on the confidentiality and integrity of WordPress sites using the Orbit Fox plugin. An attacker who gains contributor-level access can inject malicious scripts that execute in the context of any user visiting the compromised page, potentially leading to session hijacking, theft of sensitive information such as cookies or credentials, unauthorized actions performed on behalf of users, and site defacement. This can erode user trust and damage the reputation of affected organizations. Since contributor-level access is often granted to content creators or editors, the attack surface is relatively broad within organizations. The vulnerability does not directly affect availability but can indirectly cause service disruption if exploited for further attacks or if administrators take sites offline to remediate. Organizations relying on this plugin for their WordPress sites, especially those with multiple contributors, face increased risk of targeted attacks or insider threats exploiting this vulnerability.

To mitigate CVE-2025-0311, organizations should first verify if they are using the Orbit Fox by ThemeIsle plugin and identify the version in use. Immediate steps include: 1) Restrict contributor-level access to trusted users only, minimizing the risk of malicious script injection. 2) Monitor and audit content submitted via the Pricing Table widget for suspicious or unexpected scripts or HTML. 3) Apply any available updates or patches from ThemeIsle as soon as they are released; if no patch is available, consider temporarily disabling the Pricing Table widget or the plugin entirely. 4) Implement a Web Application Firewall (WAF) with rules to detect and block stored XSS payloads targeting the plugin’s parameters. 5) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected pages. 6) Educate content contributors about safe content submission practices and the risks of injecting scripts. 7) Regularly back up WordPress sites to enable quick restoration if compromise occurs. These measures combined will reduce the likelihood and impact of exploitation until a permanent patch is applied.
