Name of the Vulnerable Software and Affected Versions cpp-httplib versions v0.17.3 through v0.18.3

Description The issue allows attackers to exploit CRLF injection, which could lead to HTTP Response Splitting, XSS, and more, by not filtering CRLF characters (r ) when those are prefixed with a null byte.

Recommendations For versions v0.17.3 through v0.18.3, consider filtering CRLF characters (r ) even when prefixed with a null byte to prevent exploitation. As a temporary workaround, restrict the use of the affected function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
