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.

Attackers using Langflow flaw for credential harvesting (CVE-2026-55255)

The Cybersecurity and Infrastructure Security Agency (CISA) added CVE-2026-55255 to its Known Exploited Vulnerabilities catalog on July 7, 2026, after attackers began exploiting the flaw in the wild. The vulnerability affects Langflow, an open-source visual framework for building artificial intelligence (AI) agents and workflows used by developers, enterprises, and service providers. Threat researchers at Sysdig observed active exploitation approximately two weeks before CISA's official listing.

Why it matters: Organizations and developers using Langflow for AI workflows face immediate credential harvesting risk from exploitation of CVE-2026-55255 and should prioritize patching or disabling affected instances.
