CVE-2024-6783Public exploitNetwork attack vector

Browser script execution via inherited AST properties

Published Jul 23, 2024 · Updated Aug 30, 2024

Cross-site scripting in the Vue.js 2.0.0 through 2.7.16 template compiler allows remote attackers to execute JavaScript in browsers. The compiler reads inherited AST properties such as staticClass or staticStyle, stringifies their attacker-controlled values into render-function code, and evaluates it. Exploitation requires a polluted prototype and the full browser build's in-browser compiler; execution remains within the rendered application's browser context.
