Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Server-side request forgery in github.com/lf-edge/ekuiper/v2 versions before 2.4.0 lets an attacker who can register external services or create rules make the eKuiper server send requests to internal network addresses, loopback, or cloud metadata endpoints. An attacker needs permission to use the management API, and can then probe internal services and possibly read sensitive responses. Upgrade to version 2.4.0 or later, which blocks private, loopback, and similar addresses by default.
