CVE-2026-27112 Vulnerability Summary

CVE-2026-27112: Kargo manages and automates the promotion of software artifacts. From 1.7.0 to before v1.7.8, v1.8.11, and v1.9.3, the batch resource creation endpoints of both Kargo's legacy gRPC API and newer REST API accept multi-document YAML payloads. Specially crafted payloads can manifest a bug present in the logic of both endpoints to inject arbitrary resources (of specific types only) into the underlying namespace of an existing Project using the API server's own permissions when that behavior was not intended. Critically, an attacker may exploit this as a vector for elevating their own permissions, which can then be leveraged to achieve remote code execution or secret exfiltration. Exfiltrated artifact repository credentials can be leveraged, in turn, to execute further attacks. In some configurations of the Kargo control plane's underlying Kubernetes cluster, elevated permissions may additionally be leveraged to achieve remote code execution or secret exfiltration using kubectl. This can reduce the complexity of the attack, however, worst case scenarios remain entirely achievable even without this. This vulnerability is fixed in v1.7.8, v1.8.11, and v1.9.3.

Assessing the Risk of CVE-2026-27112

Access Complexity Graph

The exploitability of CVE-2026-27112 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-27112

No exploitability data is available for CVE-2026-27112.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-27112, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis
