About this tag
The erlang cowlib tag on WindowsForum covers security advisories and technical discussions about the ninenines cowlib library, an Erlang library for HTTP and WebSocket handling. Recent threads focus on CVE-2026-43968, a CRLF injection vulnerability in the Server-Sent Events encoder, and CVE-2026-7790, a denial-of-service flaw in the chunked HTTP parser. While these are not Windows-native vulnerabilities, they affect Windows environments that run Erlang-based services, web front ends, or cloud services depending on cowlib. Discussions emphasize dependency management, patching strategies, and the broader impact of open-source library flaws on modern Windows infrastructure.
