Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The @langchain/redis npm package, versions before 1.1.1, did not properly escape values used to build structured RediSearch TAG and TEXT filters. An attacker who can control values passed into these filters may be able to inject RediSearch syntax, altering or broadening the search query and potentially exposing indexed documents outside their intended scope. Upgrade to @langchain/redis 1.1.1 or later.
