Unknown · Cpp-Httplib · CVE-2025-0825
**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.
