Description

A Cascading Style Sheets (CSS) injection vulnerability in Swagger UI before 3.23.11 allows attackers to use the Relative Path Overwrite (RPO) technique to perform CSS-based input field value exfiltration, such as exfiltration of a CSRF token value. In other words, this product intentionally allows the embedding of untrusted JSON data from remote servers, but it was not previously known that @import within the JSON data was a functional attack method.

CWEs

  • CWE-79 · Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
