CISA Flags Langflow RCE, Tomcat, and N-central Flaws as Actively Exploited
What happened
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added three critical vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog on August 5, 2026. These include a severe remote code execution (RCE) flaw in Langflow (CVE-2026-9198) with a CVSS score of 9.8, a flaw in Apache Tomcat, and an issue affecting N-central. CISA flagged these because there is confirmed active exploitation happening in the wild.
Why it matters
CISA’s inclusion in the KEV list means organizations using Langflow, Tomcat, or N-central should prioritize immediate patching or risk compromise. The Langflow vulnerability is especially urgent due to its high severity and the fact that it allows unauthenticated attackers full remote control. Ignoring these updates leaves systems exposed to attacks that can bypass standard defenses and quickly escalate privileges, increasing the risk of massive data breaches or operational shutdowns.
What to watch next
Operators need to track the rollout of patches from the respective vendors and verify their environments are fully updated. Watch for any new attack campaigns or proof-of-concept exploits that might increase pressure on defenders. Organizations using these products should also review their incident detection and response capabilities to spot signs of exploitation early. Failure to respond swiftly will raise operational risk and increase potential cleanup costs.
