Published 2026-07-07 · first seen here 2026-10-10
CISA required action (due 2026-07-10): Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
Analysis & write-ups
No technical write-up from a research team yet. Contact Zero checks Unit 42, Google/Mandiant, Microsoft, Talos, CrowdStrike, Rapid7, watchTowr and others several times a day, plus NVD and CISA reference links.
Exploit availability
Public exploit code lowers the bar for attackers, so prioritise patching and hunting. These repositories are unverified. Fake PoCs that contain malware are common, so never run them outside an isolated lab.

Where it shows in your logs
CISA requires forensic triage for this CVE (BOD 26-04): check affected systems for signs of compromise, don't just patch.
Server or web application · Path traversal (read or write arbitrary files) medium confidence
What to look for
- Requests containing ../, ..%2f, %2e%2e%2f, ..\ or double-encoded variants
- Successful (200) responses to requests for config files, keys or password stores (web.config, /etc/passwd, .env)
- If file write is possible: new files in startup, cron or web folders
- The application's process (w3wp.exe, java, tomcat, node, php-fpm, httpd, python) starting shells or LOLBins (cmd, powershell, sh, bash, curl, wget, certutil)
- New script files in web roots (.jsp, .aspx, .php): a web shell
- Requests to unusual URLs on the application from internet IPs right before any of the above
- Outbound connections from the server to new external IPs
