CVE-2025-71337

Flowise - Unverified Email Change via Account Profile Endpoint

Published Jun 23, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed

Description

Flowise before 3.0.10 (affected versions 3.0.7 and earlier) contains an unverified email change vulnerability. An authenticated user can change the account email address, used as a login identifier and password-recovery channel, via the account profile endpoint without confirming the change to the original email address or re-entering the current password. By changing the recovery email, an attacker can take over the account and abuse password reset mechanisms.

Analysis

Technical impact

Flowise before version 3.0.10 allows an authenticated user to change the account email address, which is used for both logging in and password recovery, without confirming the change or re‑entering the current password. This flaw, classified as CWE-620, lets an attacker redirect password reset links to a malicious email, effectively hijacking the account and gaining full access.

Affected Systems

The vulnerable product is Flowise, specifically versions 3.0.7 and earlier (i.e., any release prior to 3.0.10).

Risk and Exploitability

The CVSS score of 8.7 reflects a high severity threat. Although EPSS data is not available, the vulnerability is not currently listed in the CISA KEV catalog. Exploitation only requires an authenticated session; an attacker with valid credentials can alter the recovery email, bypassing standard verification steps and enabling password reset abuse.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade to Flowise version 3.0.10 or newer, which requires verification and password confirmation for email changes.
If an immediate upgrade is not possible, temporarily disable the account email change feature or restrict it to privileged users and enforce re‑authentication before any changes.
Implement additional safeguards such as two‑factor authentication and monitor for anomalous password reset requests to mitigate further abuse.
