GHSA-65RJ-829H-6G8X

Vulnerability from github – Published: 2025-02-04 15:31 – Updated: 2025-08-04 15:31

Details

cpp-httplib version v0.17.3 through v0.18.3 fails to filter CRLF characters ("\r\n") when those are prefixed with a null byte. This enables attackers to exploit CRLF injection that could further lead to HTTP Response Splitting, XSS, and more.

Severity ?
