Attackers can craft a filename containing a closing template quoting sequence followed by an exec macro, which bypasses the authorization check in the dispatcher to execute arbitrary commands on the underlying host system.","categories":["Unclassified"],"product":"hfs2","vendor":"rejetto","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97359","source_modified_at":"2026-09-29T02:44:54.569Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"hfs2","vendor":"rejetto","versions":[{"status":"affected","version":"2.0.0","versionType":"semver","lessThanOrEqual":"2.4.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":10,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00779,"percentile":0.55432,"score_date":"2026-10-23"},"published_at":"2026-09-24T13:28:18.818Z","modified_at":"2026-09-29T02:44:54.569Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97359","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-29T02:44:54.569Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97359","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/wgetnz/hfs2/blob/master/advisories/hfs2-upload-filename-template-injection/README.md","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/hfs2-rce-via-multipart-upload-filename-template-injection","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"total","assessed_at":"2026-09-29T02:44:32.969852Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-29T02:44:54.569Z","content_hash":"2b7d4f7c32da788fdbdb283878232ac7aeb88c74d27161b1579b6ed3d25794a0"}}
