CISA Adds Three Actively Exploited Vulnerabilities to KEV Catalog Affecting Langflow, Apache Tomcat and N-central
The U.S. Cybersecurity and Infrastructure Security Agency has added three known exploited vulnerabilities to its KEV catalog, urging federal agencies to apply patches by August 7, 2026. CVE-2026-9198 affects the AI application development platform Langflow and allows unauthenticated attackers to chain API calls, obtain tokens, and execute arbitrary code. CVE-2026-34486 impacts Apache Tomcat and enables bypass of the EncryptInterceptor, leaving cluster node communications unencrypted. CVE-2026-18556 in N-able N-central permits authentication bypass through alternate channels, while an incomplete fix introduced CVE-2026-18577, which was added to the catalog one day earlier. All three issues have confirmed exploitation in the wild.
