Password Policy Bypass Vulnerability in Fides Webserver User Accept Invite API

SummaryThe user invite acceptance API endpoint lacks server-side password policy enforcement, allowing users to set arbitrarily weak passwords by bypassing client-side validation. While the UI enforces password complexity requirements, direct API calls can circumvent these checks, enabling the...

PYSEC-2026-1975 Tornado has an HTTP cookie parsing DoS vulnerability

The algorithm used for parsing HTTP cookies in Tornado versions prior to 6.4.2 sometimes has quadratic complexity, leading to excessive CPU consumption when parsing maliciously-crafted cookie headers. This parsing occurs in the event loop thread and may block the processing of other requests. See...
