CISA Warns of Exploited Langflow, N-central, and Tomcat Vulnerabilities
The US Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday warned that threat actors have been exploiting three vulnerabilities in IBM Langflow OSS, N-able N-central, and Apache Tomcat.
Tracked as CVE-2026-9198 (CVSS score of 9.8), the Langflow OSS bug allows unauthenticated attackers to chain two API endpoints for remote code execution.
It was disclosed on July 17, when IBM rolled out patches for it, in Langflow OSS version 1.10.1, warning that all default deployments are affected.
“The vulnerability combined two distinct issues: an unauthenticated endpoint that issued superuser bearer tokens to any network caller, and a code validation endpoint that executed arbitrary Python code. An attacker could chain these vulnerabilities by first obtaining a superuser token from the auto-login endpoint, then using that token to submit malicious code to the validation endpoint,” IBM warned.
Proof-of-concept (PoC) code targeting the security defect was published roughly a week after the public...
