Detailsinfo

A vulnerability has been found in akuity kargo up to 1.6.3/1.7.8/1.8.11/1.9.4 and classified as problematic. This vulnerability affects an unknown part of the component Cloud Instance Metadata Endpoint. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability was named CVE-2026-32828 since 03/16/2026. The exploitation appears to be easy. The attack can be initiated remotely. The exploitation needs additional levels of successful authentication. The technical details are unknown and an exploit is not available.

Upgrading to version 1.6.4, 1.7.9, 1.8.12 or 1.9.5 eliminates this vulnerability. Applying the patch fd25620c2473ed19bec4be4d0f181287ef0f0391 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
