mjson

The mjson tag on WindowsForum.com covers discussions about the mjson JSON parser, particularly in the context of security vulnerabilities. A recent thread details CVE-2025-11230, a high-severity denial-of-service flaw in HAProxy's embedded mjson parser. This vulnerability stems from inefficient algorithm complexity (CWE-407) in the mystrtod routine, where specially crafted JSON payloads with extremely large numeric values can cause HAProxy processes to hang or crash, taking reverse proxy and ingress services offline. The tag is relevant for IT professionals and system administrators managing HAProxy deployments who need to understand and mitigate this security issue through patching.
