{"schema":"threatline.record/2","record":{"id":"CVE-2026-103754","aliases":[],"summary":"Ansible-runner: ansible-runner: path traversal and symlink escape in unstream_dir() allows file write outside the target directory","details":"A flaw was found in ansible-runner. The unstream_dir() function, which receives and extracts a streamed zip archive on the worker side of the ansible-runner transmit/worker protocol, re-creates symbolic links from archive content without validating the link target and applies chmod() and utime() to an unsanitized filesystem path derived from the archive member name. A crafted archive processed by a worker that consumes attacker-influenced input can create files, create symbolic links, or change permissions outside the intended target directory, which can be leveraged toward code execution.","categories":["Operating systems"],"product":"Red Hat Ansible Automation Platform 2","vendor":"Red Hat","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-103754","source_modified_at":"2026-10-16T09:46:45.990Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Ansible Automation Platform 2","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-103754","source_modified_at":"2026-10-16T09:46:45.990Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Ansible Automation Platform 2","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":5.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00335,"percentile":0.25743,"score_date":"2026-10-23"},"published_at":"2026-10-01T11:57:07.822Z","modified_at":"2026-10-16T09:46:45.990Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-103754","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T09:46:45.990Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-103754","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-103754","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2544510","tags":["issue-tracking","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://github.com/ansible/ansible-runner/pull/1550"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-01T13:20:19.192040Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-16T09:46:45.990Z","content_hash":"c440fada6b09a5ca0a85728253d28c96c3f4b7a12080c52e96c59a871199d4dd"}}
