Medium SSRF

CVE-2026-32828 — Kargo: SSRF in Promotion http/http-download Steps Enables Internal Network Access and Data Exfiltration

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.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.4% (30-day exploitation probability)+5
Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.
