crlf injection

CRLF injection is a security vulnerability that occurs when an attacker injects carriage return and line feed characters into an application, enabling HTTP response splitting or header smuggling. On WindowsForum.com, discussions cover real-world examples such as CVE-2026-3633 in libsoup, where improper escaping of the method parameter allows CRLF injection and request smuggling. Another thread examines critical Azure DevOps vulnerabilities that could be exploited via similar injection techniques, threatening CI/CD pipeline security. These threads highlight the importance of input validation and proper encoding to prevent CRLF injection attacks in web applications and enterprise environments.
