CVE-2026-41275Public exploitNetwork attack vector

Account takeover via cleartext password reset link

Published Apr 23, 2026 · Updated Apr 23, 2026

Cleartext transmission in Flowise before 3.1.0 allows man-in-the-middle attackers to capture password-reset tokens over HTTP. The cloud.flowiseai.com password-reset workflow places its token-bearing reset URL behind an HTTP link instead of an HTTPS endpoint. Exploitation requires a user to open the emailed link across a network position the attacker can monitor, after which the captured token grants control of that user's account.
