n8n just got a CVSS 10.0 public exploit.
CVE-2026-21858 (“Ni8mare”):

unauthenticated file read → full RCE. Working PoC is circulating.

Any internet-facing n8n that missed the patch is one request away from compromise.

Security Researcher Alexander Hagenah has developed a proof-of-concept which programmatically extracts data out of Microsoft Recall

@vixentael Glory to Ukraine!

Ukraine has submitted its application against Russia to the ICJ. Russia must be held accountable for manipulating the notion of genocide to justify aggression. We request an urgent decision ordering Russia to cease military activity now and expect trials to start next week.

If files outside of the document root are not protected by "require all denied" these requests can succeed.

I was told you like SCCM passwords & #mimikatz 🥝

Did you know SCCM *endpoints* can keep credentials of all your Network Access Accounts?

Time to try the new dpapi::sccm command and to check privileges associated to them 😉
