Note: Versions mentioned in the description apply only to the upstream open-webui package and not the open-webui package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

NLTK before 3.10.3 contains an uncontrolled recursion vulnerability in nltk.featstruct.FeatStructReader that allows unauthenticated attackers to cause a denial of service by supplying deeply nested feature-structure input. Attackers can craft trivial payloads with nested brackets that exceed Python's recursion limit and raise an unhandled RecursionError, crashing applications that parse user-supplied feature structures or feature grammars.
