{"schema":"threatline.record/2","record":{"id":"CVE-2026-86018","aliases":["GHSA-2whx-2cx7-qvq6"],"summary":"Part-DB: Authenticated Disk Exhaustion via Unbounded Server-Side Attachment Downloads","details":"Part-DB is an open source inventory management system for electronic components. Prior to version 2.13.2, Part-DB allows authenticated users to bypass the configured maximum attachment file size when using the server-side “Download external file” attachment feature. When server-side attachment downloads are enabled, Part-DB downloads the remote file and streams it directly to disk without enforcing the configured MAX_ATTACHMENT_FILE_SIZE limit. As a result, an authenticated user who can create or edit attachments can cause Part-DB to store files larger than the configured maximum attachment size, potentially exhausting disk space and causing a denial of service. This issue has been patched in version 2.13.2.","categories":["Unclassified"],"product":"Part-DB-server","vendor":"Part-DB","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-86018","source_modified_at":"2026-10-23T04:00:19.188Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Part-DB-server","vendor":"Part-DB","versions":[{"version":"< 2.13.2","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00272,"percentile":0.1856,"score_date":"2026-10-23"},"published_at":"2026-10-23T04:00:19.188Z","modified_at":"2026-10-23T04:00:19.188Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-86018","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T04:00:19.188Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-86018","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/Part-DB/Part-DB-server/security/advisories/GHSA-2whx-2cx7-qvq6","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/Part-DB/Part-DB-server/releases/tag/v2.13.2","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T04:00:19.188Z","content_hash":"fe560d3d9ae0ffc1098d8b874829c2ba12d748cfd183096eb6bac7d31b592860"}}
