The person who wrote the widely-referred-to tweet last night (claiming to "have recreated & lab/field tested CVE-2026-109618 / CVE-2026-109619") followed up a couple hours later and said that their POC had not been proven to work "in the wild"
replyThe whole post looked to be vibecoded and the code did not even match the claims
replyAs far as i know they lied and are now retracting their claims. What they posted was not consistent with the details of the real bug.
replyCloudflare's blog post announcing its updated WAF rules directly implies the existence of in-the-wild exploits: https://blog.cloudflare.com/php-vulnerabilities-waf-protecti...
reply"Cloudflare successfully deployed multiple mitigations for all its customers while the vulnerability was leaked before the official release date and we observed attack traffic targeting our customers."
If that's not an in-the-wild exploit, it literally couldn't have been further away than one or two more iterations.
Attack traffic doesn’t necessarily mean the attacks were, or would have, succeeded.
replyFrom Cloudflare’s perspective, there is no downside to saying what they observed, and deploying defenses.
We may never know if this was actually being successfully exploited prior to patch availability.
You shouldn't wait until the attacks succeed to start deploying defenses.
replyThat sounds like cloudflare trying to reassure paranoid customers. I think its a reach to go from that statement to actual in the wild exploits.

replyChainguard most likely interpreted Calif's dancing anime girl video as a script kiddie who had found a POC.
replyCan you blame them? Calif's unbelievably unprofessional video's leak definitely spikes the cortisol of any actual professional.
replyIt sounds like there was no "co-ordination" behind any of this co-ordinated disclosure. You'd have expected there to be an IRC channel, a mailing list, a Slack chat, or something for something of this scale.
replyWas there even an incident co-ordinator here? Was any of the parties talking to each other?
And then decided to not ask the PHP foundation about it?
