The short answer

CVE-2026-128332 affects knadh listmonk and is rated critical (CVSS 9.1). It is not in CISA's Known Exploited Vulnerabilities catalog.

What it is

Listmonk 6.0.0 before 7.0.0-beta.2 contains a 2FA bypass vulnerability that allows attackers with a valid password to brute-force TOTP codes because the attempt counter resets on every new password login. Attackers can repeatedly submit credentials to POST /admin/login to obtain fresh tokens, each allowing 15 more guesses, gaining sessions for 2FA-protected accounts including Super Admin.

Weakness: CWE-307.
