Machine-written summary

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

The jmespath gem for Ruby, versions before 1.6.1, uses JSON.load where JSON.parse would be safer. The source gives few details about how an attacker would reach this code or what they could do with it. Upgrade jmespath to version 1.6.1 or later.
