Bottom line: A critical vulnerability in Flowise with an exploitation probability of over 50 percent enables account takeover and remote code execution, which is why affected installations should be patched immediately.
A critical security vulnerability has been identified in Flowise, the low-code platform for building AI agents, with an exploitation probability of over 50 percent. Affected installations are exposed to the risk of account takeover, data exfiltration, and remote code execution.
Security researchers have identified a critical vulnerability in Flowise, the open-source platform used to build AI agents and LLM workflows via a low-code approach. The exploitation probability is stated at over 50 percent, which clearly sets this vulnerability apart from many other vulnerability reports. According to the source, in addition to this critical flaw, further vulnerabilities were found in the platform that together create a broader risk profile for operators of Flowise instances.
According to reporting, the combination of vulnerabilities allows account takeover, unauthorized access to stored data, and, in the worst case, remote code execution on the underlying system. Since Flowise is frequently used to orchestrate AI agents with access to internal data sources, APIs, and credentials, a successful attack extends beyond mere system access: attackers could also reach downstream systems and business processes via compromised agents.
For CISOs responsible for or overseeing the use of AI agent frameworks within the enterprise, this creates an immediate need for action. All Flowise instances should have their version status checked and should be promptly updated to the patched versions provided by the vendor. In parallel, it is advisable to review which access rights and data connections have been granted to the affected Flowise deployments in order to limit the potential damage in the event of a compromise.
Since the source does not provide any CVE identifiers, affected version numbers, or technical details on the attack vectors, security officers should consult the vendor’s information and advisories directly from Flowise or in relevant CVE databases to verify the specific patch level and exposure of their own environment.
