Our security research team discovered a cross-site scripting vulnerability in Cloudflare's /cdn-cgi/image/ endpoint by chaining an SVG sanitizer bypass with a new Cache-Control header trick to bypass the CSP. The issue was reported to Cloudflare and has since been fixed.

EXCLUSIVE: In less than 12 hours, a group of ex-DOGE cyber researchers were able to penetrate Anthropic’s systems using AI agents — including Slack channels where the most sensitive models are discussed.
This is just weeks after
Anthropic whistleblower Joseph Coxon charged the company w/launching “a hubristic gamble” from a “private company’s Slack.”

In the 4 days since php2shell was published:
* 1,448 more CVEs published.
* No published exploit code for any in Metasploit or Exploit-DB.
* VulnCheck added 25 on its KEV list. 24 are old bugs.
* CISA added just 1 to its KEV list, the only new bug anyone has seen adversaries exploit.
Nothing in the record shows AI or anything else driving up how many vuln adversaries exploit, or how fast. Adversaries keep working a small set of bugs until those stop paying, and only then move on.
Patch php2shell because there are too many eyes are on it not to. Then apply the same rule to everything else, prioritize patching all systems against what adversaries exploit. It sounds simple, and the evidence says it’s what we still haven’t done that actually works.

Node2Shell (CVE-2026-111497): Imperva demonstrated RCE on stock Node.js 24.22.0 (Linux arm64) via attacker-controlled Brotli decoded by fetch() or request parsers.
Invalid block transition → OOB write. Patched in 24.22.1. PoC required multiple attempts.

Liked PHP2Shell? You’re gonna love Node2Shell.
We reproduced CVE-2026-111497 as pre-auth RCE. On a vulnerable Node.js runtime, app.use(express.json()) is enough to expose your server to code execution through a single Brotli request. Patch your systems now!

🚨 PHP2Shell detection is now available in Burp Suite Professional & Burp Suite DAST.
Most of the web is powered by PHP, which means most of the web is vulnerable to these critical unauthenticated remote code execution flaws (CVE-2026-109618 / 109619). You can already detect it in Burp Suite using:
🟧 ActiveScan++ v2.0.13 (portswigger.net/bappstore/31…)
🟧 Bambda scan checks (github.com/PortSwigger/bambd…)
🟧 BChecks (github.com/PortSwigger/bchec…)
Start scanning for the vulnerability now → portswigger.net/bappstore/31…

We had a security breach last night related to a large scale distillation attack that impacted 1.4% of OpenCode Console users
We have notified them all this morning via email. If you did not get an email you were not impacted, it was a subset of users who had external providers linked
The incident is ongoing so we cannot share more details at this point but we are working with Anthropic, OpenAI, and Google to remediate
