CVE-2026-57439 · CyberChef: Prototype pollution in Series Chart operation
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
CyberChef is a web app for encryption, encoding, compression, and data analysis. Prior to 11.2.0, the Series Chart operation accepts __proto__ as a key while parsing user-supplied CSV, allowing prototype pollution that can be chained with operations such as Parse UDP to inject malicious JavaScript into HTML output. This issue is fixed in version 11.2.0.
