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.","cvss_v4":{"vector":"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","score":9.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H","score":8.4},"cwes":["CWE-22"],"references":["https://github.com/home-assistant/core/commit/1e457600f1093c15e1325742d03e2b76498c79c1","https://github.com/home-assistant/core/pull/172252","https://github.com/home-assistant/core/releases/tag/2026.7.0","https://www.vulncheck.com/advisories/home-assistant-core-symlink-path-traversal-rce-via-backup-restore","https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-78r8-wwqv-r299"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-64824","score":0.00713,"percentile":0.53362,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-78r8-wwqv-r299","url":"https://osv.dev/vulnerability/GHSA-78r8-wwqv-r299","summary":"PraisonAI: Arbitrary code execution via unguarded `spec.loader.exec_module` in `agents_generator.py` - sibling of CVE-2026-44334","modified":"2026-07-22T05:41:40.373068812Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<4.6.40"],"fixed":["4.6.40"]}]},{"id":"PYSEC-2026-2905","url":"https://osv.dev/vulnerability/PYSEC-2026-2905","summary":"PraisonAI: Arbitrary code execution via unguarded `spec.loader.exec_module` in `agents_generator.py` - sibling of CVE-2026-44334","modified":"2026-07-22T05:41:40.373068812Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<4.6.40"],"fixed":["4.6.40"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
