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.

What engineer at cloudflare thought this was a good resolution?

I doubt the system is that simple. No one wrote a rule saying `if url.contains("camel") then block()` it's probably an unintended side-effect

If this is a bet, I'll happily take the other side and give you 4:1 on it.

Akamai has been doing precisely that for years & years...

I think you can include advertising/privacy block lists in that vein too, although that allows for the users to locally-correct any issues.

Judging by previous outages it was probably a poorly tested overcomplicated regex which matched to much.
WAFs are literally "a pile of regexes can secure my insecure software"
mschuster91 1 days ago [-]
To be fair to WAFs, most are more than just a pile of regexes. Things like detecting bot traffic - be it spammers or AI scrapers - are valuable (ESPECIALLY the AI scraper detection, because unlike search engines these things have zero context recognition or respect for robots.txt and will just happily go on and ingest very heavy endpoints), and the large CDN/WAF providers can do it even better because they can spot shit like automated port scanners, Metasploit or similar skiddie tooling across all the services that use them.
Honestly what I'd _love_ to see is AWS, GCE, Azure, Fastly, Cloudflare and Akamai band together and share information about such bad actors, compile evidence lists and file abuse reports against their ISP - or in case the ISP is a "bulletproof hoster" or certain enemy states, initiate enforcement actors like governments to get these bad ISPs disconnected from the Internet.

Why would scrapes get blocked, is scrapping illegal?
Xylakant 22 hours ago [-]
It's very often not, but it's still the website owners property and if they choose so, they can show misbehaving guests the door and kindly ask to remain on the other side (aka block them). Large scale scraping puts substantial burden on web properties. I was paged the other night because someone decided it would be a great idea to throw 200 000rq/s for a few minutes at some publicly available volunteer run service.

I don't know if it is, but I also don't think we are required to let dumb bots repeatedly assault or web sites if we can find a technical way to get around it.

They do mitigate known vulnerabilities.

But are they less shit than the shitty software they filter traffic for?

I wouldn't say that. The postmortem you referred to links to another CloudFlare blog post - one about a pretty serious RCE vuln in Microsoft SharePoint that was blocked by their WAF: https://blog.cloudflare.com/stopping-cve-2019-0604/

I mean, it's hardly surprising CloudFlare will tell you this is a useful product. But it is to securing a web application what regex is to parsing HTML.

Sadly I work with web developers that all assume they don’t need to bother too much with security “because we have a WAF”.
AdamJacobMuller 1 days ago [-]
I'm not sure why "WAF has false positives" makes it useless, nor would I say this is anywhere near the scale of "breaking the internet" and I'm not even fan of the concept of WAFs in general.

The last one took out a lot more stuff than this one but the argument is the same - this product is a checkmark thing and when it's not fulfilling its checkmark purpose, it causes outages. Still an amusing bi-modality! I suppose it shares it with DNSSEC.

Basically CF default WAF settings saved more small and medium companies I can even count to.
I’m not CF fan, but WAFs (with rate limiting) do help. Sad that one or two incidents for that complicated and big services make people post such comments, but cmon - it doesn’t have AI in it's name so sheeps have to cry, right?

we've used it to rescue some vintage appliances that are basically unsecurable.
That rule can be overridden if you're having this issue on your own site.

I would have thought a large company like GitHub or Microsoft can have their own WAF team for their apps.
