Because the official Docker image runs the Home Assistant process as root and the subsequent regular-file entry is written through the unvalidated symlink, attackers can achieve remote code execution by overwriting auto-imported Python paths such as site-packages/sitecustomize.py or custom component directories." } ], "tags": [ "x_open-source" ], "datePublic": "2026-05-27T00:00:00.000Z", "problemTypes": [ { "descriptions": [ { "lang": "en", "cweId": "CWE-22", "description": "Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')", "type": "CWE" } ] } ], "affected": [ { "defaultStatus": "affected", "vendor": "home-assistant", "product": "Home Assistant Core", "packageURL": "pkg:github/home-assistant/core", "repo": "https://github.com/home-assistant/core", "versions": [ { "status": "affected", "version": "0", "versionType": "semver", "lessThan": "2026.7.0" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:a:home-assistant:home-assistant:*:*:*:*:*:*:*:*", "versionEndExcluding": "2026.7.0" } ] } ] } ], "metrics": [ { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV4_0": { "attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "NONE", "privilegesRequired": "HIGH", "userInteraction": "ACTIVE", "vulnConfidentialityImpact": "HIGH", "subConfidentialityImpact": "HIGH", "vulnIntegrityImpact": "HIGH", "subIntegrityImpact": "HIGH", "vulnAvailabilityImpact": "HIGH", "subAvailabilityImpact": "HIGH", "exploitMaturity": "NOT_DEFINED", "Safety": "NOT_DEFINED", "Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "valueDensity": "NOT_DEFINED", "vulnerabilityResponseEffort": "NOT_DEFINED", "providerUrgency": "NOT_DEFINED", "version": "4.0", "baseSeverity": "CRITICAL", "baseScore": 9.3, "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H" } }, { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV3_1": { "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "HIGH", "userInteraction": "REQUIRED", "scope": "CHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "version": "3.1", "baseSeverity": "HIGH", "baseScore": 8.4, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H" } } ], "references": [ { "url": "https://github.com/home-assistant/core/releases/tag/2026.7.0", "name": "Release Notes", "tags": [ "release-notes" ] }, { "url": "https://github.com/home-assistant/core/pull/172252", "name": "Pull Request", "tags": [ "issue-tracking" ] }, { "url": "https://github.com/home-assistant/core/commit/1e457600f1093c15e1325742d03e2b76498c79c1", "name": "Patch Commit", "tags": [ "patch" ] }, { "url": "https://www.vulncheck.com/advisories/home-assistant-core-symlink-path-traversal-rce-via-backup-restore", "tags": [ "third-party-advisory" ] } ], "credits": [ { "lang": "en", "value": "Harish Kolla (@Har1sh-k)", "type": "finder" } ], "source": { "discovery": "UNKNOWN" }, "x_generator": { "engine": "vulncheck" } }, "adp": [ { "references": [ { "url": "https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-78r8-wwqv-r299", "tags": [ "exploit" ] } ], "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-07-21T16:35:40.370650Z", "id": "CVE-2026-64824", "options": [ { "Exploitation": "poc" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-07-21T16:37:32.731Z" } } ] } }
