Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The lightrag-hku PyPI package before 1.4.14 accepts JWTs signed with the "none" algorithm because its token validation does not restrict the allowed algorithms. An unauthenticated attacker who can reach the API can forge a token without a signature and impersonate any user, including administrators. Upgrade to lightrag-hku 1.4.14 or later.
