CWE-113

Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting')

The product receives data from an HTTP agent/component (e.g., web server, proxy, browser, etc.), but it does not neutralize or incorrectly neutralizes CR and LF characters before the data is included in outgoing HTTP headers.

Impactr finds and proves whether CWE-113 — or flaws like it — are actually reachable in your own web apps and APIs, with a reproducible exploit as evidence.
