CVE-2014-9772: The validator package before 2.0.0 for Node.js allows remote attackers to bypass the cross-site scripting (...

Security readout for executives and security teams

This CVE concerns the Node.js validator package before version 2.0.0. Its XSS filter could be bypassed using hex-encoded characters, so applications relying on that filter could allow unsafe content through. The source bundle does not provide CVSS, CWE, or active exploitation evidence. Exposure is most likely in older Node.js applications using validator before 2.0.0, especially where the package's XSS filter protects stored or reflected user input. The bundle does not identify specific downstream products or deployments. Treat this as a targeted dependency cleanup item unless legacy applications rely heavily on validator for XSS protection. Prioritize internet-facing systems that render user-submitted content, because successful bypass could affect users through browser-side script execution. Mitigation focus: Inventory Node.js applications for validator versions before 2.0.0.; Upgrade validator to 2.0.0 or a later supported version.; Review code paths relying on validator's XSS filter for user content..
