Detailsinfo

A vulnerability classified as problematic has been found in FlowiseAI Flowise up to 3.0.x. This affects an unknown code block. The manipulation with an unknown input leads to a cleartext transmission vulnerability. CWE is classifying the issue as CWE-319. The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors. This is going to have an impact on confidentiality. The summary by CVE is:

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, the password reset functionality on cloud.flowiseai.com sends a reset password link over the unsecured HTTP protocol instead of HTTPS. This behavior introduces the risk of a man-in-the-middle (MITM) attack, where an attacker on the same network as the user (e.g., public Wi-Fi) can intercept the reset link and gain unauthorized access to the victim’s account. This vulnerability is fixed in 3.1.0.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-41275 since 04/18/2026. The exploitability is told to be difficult. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1040 for this issue.

Upgrading to version 3.1.0 eliminates this vulnerability.

The vulnerability is also documented in the databases at EUVD (EUVD-2026-25291) and CERT Bund (WID-SEC-2026-1145). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
