Active-user disclosure via unauthenticated endpoint
Published Feb 16, 2023 · Updated Mar 18, 2025
Information disclosure in Palantir Gotham before 3.22.10.4 allows remote attackers to enumerate active usernames without authentication. The unnamed endpoint returns every username with an active session without verifying the requester’s identity. Repeated requests reveal when personnel are active, exposing names and usage timing that can support targeted phishing.
