CVE-2019-17495: Cross-site scripting in Swagger-UI

October 15, 2019 (updated August 26, 2024)

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.
