CVE-2022-27897Network attack vector

Unauthenticated service interruption via unbounded ZIP uploads

Published Feb 16, 2023 · Updated Mar 18, 2025

Improper input validation in Palantir Gotham before 3.22.11.2 allows remote attackers to interrupt Dispatch via crafted ZIP uploads. An unauthenticated upload endpoint loads portions of each maliciously crafted ZIP archive into memory without adequately bounding resource use. Repeated requests exhaust Dispatch server memory, interrupting a core service that enforces access control, generates logs, and coordinates database-bound requests.
