Kargo manages and automates the promotion of software artifacts. In versions 1.4.0 through 1.6.3, 1.7.0-rc.1 through 1.7.8, 1.8.0-rc.1 through 1.8.11, and 1.9.0-rc.1 through 1.9.4, the http and http-download promotion steps allow Server-Side Request Forgery (SSRF) against link-local addresses, most critically the cloud instance metadata endpoint (169.254.169.254), enabling exfiltration of sensitive data such as IAM credentials. These steps provide full control over request headers and methods, rendering cloud provider header-based SSRF mitigations ineffective. An authenticated attacker with permissions to create/update Stages or craft Promotion resources can exploit this by submitting a malicious Promotion manifest, with response data retrievable via Promotion status fields, Git repositories, or a second http step. This issue has been fixed in versions 1.6.4, 1.7.9, 1.8.12 and 1.9.5.

Kargo Vulnerable to SSRF in Promotion http/http-download Steps Enables Internal Network Access and Data Exfiltration
## Summary
Kargo's built-in `http` and `http-download` promotion steps execute outbound HTTP requests from the Kargo controller. By design, these steps do not restrict destination addresses, as there are legitimate use cases for requests to internal and private endpoints. However, this also permits requests to link-local addresses, for which there are no known, legitimate use cases. Of particular concern is the cloud instance metadata endpoint (often `169.254.169.254`), which is unauthenticated and can expose sensitive configuration data including IAM credentials. While cloud providers typically implement header-based SSRF mitigations for these endpoints, the `http` step p
