GHSA-82RV-H33P-2XGC

Vulnerability from github – Published: 2022-06-03 00:01 – Updated: 2024-03-27 15:30

Details

The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a different URL usingthe wrong host name when it is later retrieved.For example, a URL like http://example.com%2F127.0.0.1/, would be allowed bythe parser and get transposed into http://example.com/127.0.0.1/. This flawcan be used to circumvent filters, checks and more.

Severity ?

7.5 (High)
