Seems to be a change in Cloudflare's managed WAF ruleset - any site using that will have URLs containing 'camel' blocked due to the 'Apache Camel - Remote Code Execution - CVE:CVE-2025-29891' (a9ec9cf625ff42769298671d1bbcd247) rule.
That rule can be overridden if you're having this issue on your own site.
