If a plugin is compromised, this lowers the level of access that an attacker needs to modify a plugin's install hooks, causing a local execution attack. To perform this attack, an attacker must have write access to the git repository or plugin archive (.tgz) while being downloaded (which can occur during a MITM attack on a non-SSL connection). This issue has been patched in Helm 2.16.11 and Helm 3.3.2. As a possible workaround make sure to install plugins using a secure connection protocol like SSL." } ] }, "impact": { "cvss": { "attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 3, "baseSeverity": "LOW", "confidentialityImpact": "NONE", "integrityImpact": "LOW", "privilegesRequired": "LOW", "scope": "CHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:L/A:N", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "{\"CWE-694\":\"Use of Multiple Resources with Duplicate Identifier\"}" } ] }, { "description": [ { "lang": "eng", "value": "{\"CWE-74\":\"Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')\"}" } ] } ] }, "references": { "reference_data": [ { "name": "https://github.com/helm/helm/security/advisories/GHSA-c52f-pq47-2r9j", "refsource": "CONFIRM", "url": "https://github.com/helm/helm/security/advisories/GHSA-c52f-pq47-2r9j" }, { "name": "https://github.com/helm/helm/commit/d9ef5ce8bad512e325390c0011be1244b8380e4b", "refsource": "MISC", "url": "https://github.com/helm/helm/commit/d9ef5ce8bad512e325390c0011be1244b8380e4b" } ] }, "source": { "advisory": "GHSA-c52f-pq47-2r9j", "discovery": "UNKNOWN" } }
