Description
Gotenberg versions from 8.10.0 up to but not including 8.33.0 contain a race condition vulnerability in the newContext function. This flaw allows unauthenticated remote attackers to cause a denial of service by triggering concurrent map writes, which crash the process. The issue is fixed in version 8.33.0.
