Attackers using Langflow flaw for credential harvesting (CVE-2026-55255)
The US Cybersecurity and Infrastructure Security Agency (CISA) added CVE-2026-55255 to its Known Exploited Vulnerabilities catalog after the Sysdig Threat Research Team observed active exploitation of a Langflow vulnerability. Langflow is an open-source framework for building AI agents and workflows used by developers, enterprises, and service providers. Attackers are leveraging this flaw for credential harvesting.
Why it matters: Organizations running Langflow for AI workflows face immediate credential theft risk; developers and enterprises should prioritize patching this vulnerability, which is already being actively exploited in the wild.
