CVE-2026-44939: CWE-95 Improper neutralization of directives in dynamically evaluated code ('eval injection') in SUSE Rancher
CVE-2026-44939 is a critical command injection vulnerability in SUSE Rancher Manager cluster versions before 2.14.2. The flaw exists in the import endpoint /v3/import/{token}_{clusterId}.yaml, where unsanitized YAML parameters allow remote attackers to execute malicious containers by breaking out of an image. This vulnerability affects multiple Rancher versions from 2.10.0 up to but not including 2.14.2.
AI Analysis
Technical Summary
This vulnerability (CWE-95) involves improper neutralization of directives in dynamically evaluated code, specifically 'eval injection', in the Rancher Manager import endpoint. Unsanitized YAML input parameters can be exploited by remote attackers to perform command injection, enabling execution of arbitrary containers. The issue affects Rancher versions prior to 2.14.2, with a CVSS 4.0 base score of 9.4 indicating high severity and exploitability without privileges or user interaction.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary commands by injecting malicious containers through the import endpoint. This can lead to full compromise of the Rancher cluster environment, potentially impacting confidentiality, integrity, and availability of the managed container infrastructure.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been documented in the provided data. Users should monitor SUSE's advisories for updates and apply patches once available. Until then, restricting access to the import endpoint and validating YAML inputs may reduce risk.
