waf parsing

The waf parsing tag covers discussions about changes in how web application firewalls (WAFs) parse incoming requests, particularly in the context of Cloudflare's December 5, 2025 outage. That incident was triggered by a modification to Cloudflare's WAF parsing logic, implemented in response to a recently disclosed vulnerability, which caused a brief but widespread disruption affecting dozens of high-profile websites and apps. Topics include the technical details of the parsing change, its impact on global services, and the broader implications for WAF configuration and vulnerability response. The tag is relevant for IT professionals and system administrators managing WAF rules and edge security.
