Machine-written summary

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

Kargo (Go module github.com/akuity/kargo) versions 1.4.0 to before 1.6.4, 1.7.0-rc.1 to before 1.7.9, 1.8.0-rc.1 to before 1.8.12, and 1.9.0-rc.1 to before 1.9.5 are affected. The built-in http and http-download promotion steps can send requests from the controller to link-local addresses, including cloud instance metadata endpoints, which can expose credentials. An attacker with high privileges, such as permission to create or update a Stage or a Promotion, can exploit this over the network without user interaction. Upgrade to 1.6.4, 1.7.9, 1.8.12, 1.9.5, or later.
