CVE-2023-46595

Credential theft via stored HTML injection

Published Nov 2, 2023 · Updated Nov 12, 2025

Stored HTML injection in AlgoSec FireFlow A32.20, A32.50, and A32.60 allows remote authenticated users to steal Net-NTLM hashes. The editor stores special HTML from workflow Name and Description fields and outbound-action Name and Category fields, then executes it on list and entity pages. An authenticated attacker must save a crafted value and a domain user must view the affected page, causing the browser to disclose authentication material usable in relay attacks.
