## Affected

- Palantir Gotham: fixed in 3.22.11.2

## Description

Palantir Gotham versions prior to 3.22.11.2 included an unauthenticated endpoint that would load portions of maliciously crafted zip files to memory. An attacker could repeatedly upload a malicious zip file, which would allow them to exhaust memory resources on the dispatch server.
