Project.is_path_in_project() normalizes paths lexically without resolving symlinks, so file tools like read_file and create_text_file can read or overwrite files such as SSH keys or cloud credentials.","categories":["Unclassified"],"product":"serena","vendor":"oraios","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109965","source_modified_at":"2026-10-13T15:29:52.632Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"serena","vendor":"oraios","versions":[{"version":"0","lessThan":"2.0.0","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109965","source_modified_at":"2026-10-13T15:29:52.632Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"serena","ecosystem":null},"version":"2.0.0","basis":"first unaffected version stated in the CVE record"}],"cvss":8.4,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00223,"percentile":0.12246,"score_date":"2026-10-23"},"published_at":"2026-10-13T14:00:17.324Z","modified_at":"2026-10-13T15:29:52.632Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109965","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T15:29:52.632Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109965","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/oraios/serena/issues/2144","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/oraios/serena/commit/6f20f9b822d85bb063008e786f808d04619dd54e","tags":["patch"]},{"source":"CVE List","url":"https://github.com/oraios/serena/releases/tag/v2.0.0","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/oraios/serena/blob/v1.7.0/src/serena/project.py","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/oraios/serena","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/serena-before-2.0.0-symlink-following-in-file-tools-allows-access-outside-project-root","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":"no","technical_impact":"total","assessed_at":"2026-10-13T15:29:06.118866Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-13T15:29:52.632Z","content_hash":"bf513a83d5c340097476f36cad206880bfd29c9aed67a9b11866ecf8a691eaf8"}}
