Flowise RCE Exploit Code Publicly Released

Exploit code for a critical one-click Remote Code Execution (RCE) vulnerability in Flowise has been publicly released, according to SecurityWeek. This flaw allows attackers to execute arbitrary code on self-hosted Flowise servers. The attack vector is straightforward: users are tricked into importing a malicious chatflow, which then triggers the RCE.

This isn’t theoretical; the exploit is out there. Defenders need to understand the attacker’s calculus here: it’s a social engineering play combined with a critical technical flaw. The bar for execution is low, requiring only a single click from a user. This makes it a high-probability attack if an organization is running vulnerable Flowise instances.

For CISOs, the message is clear: unpatched Flowise deployments are now a significant liability. The public availability of exploit code drastically reduces the skill required for adversaries to leverage this vulnerability. It will quickly move from targeted attacks to widespread opportunistic scanning and exploitation by less sophisticated groups. Patching is no longer a recommendation; it’s an immediate imperative.
