The sudoPassword field from the request body is written to the stdin of a 'sudo -S sh' child process; when sudo does not prompt for a password (the process runs as root, NOPASSWD is configured, or a recent sudo timestamp cache exists), sh executes the value as a shell command, letting a remote unauthenticated attacker run arbitrary OS commands. The Shadowserver Foundation first observed exploitation on 2026-07-04 (UTC).","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-59800","publishedAt":"2026-07-07T19:16:55.260Z","cveId":"CVE-2026-59800","cweIds":["CWE-78"],"cvssScore":"9.8","cvssSeverity":"critical","severity":"critical","attackType":["other"],"issueType":"vulnerability","affectedPackages":["9router@< 0.4.44 (fixed: 0.4.44)"],"affectedPackageNames":["9router"],"affectedPackageRefs":["npm:9router"],"affectedVendors":[],"affectedVendorsRaw":["9Router"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"9Router OS command injection through unauthenticated Tailscale install endpoint","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","attackVector":"network","attackComplexity":"low","privilegesRequired":"none","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.02043,"epssCheckedAt":"2026-10-14T18:05:58.477Z","kevDateAdded":null,"advisoryAliases":["GHSA-g6g7-pvmx-m74p"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:46:59.511Z","patchAvailable":true,"disclosureDate":"2026-07-07T19:16:55.260Z","capecIds":["CAPEC-88"],"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.6,"researchCategory":null,"atlasIds":null}}
