{"id":"CVE-2026-86019","summary":"Part-DB: Attachment Size Limit Bypass via API Base64 Upload","details":"Part-DB is an open source inventory management system for electronic components. Prior to version 2.13.2, Part-DB allows authenticated API users to bypass the configured maximum attachment file size by uploading attachments through the API using base64-encoded file data. The application enforces the configured attachment size limit for normal browser-based file uploads, but the API base64 upload path does not apply the same size validation. As a result, an authenticated user with API access and permission to create attachments can upload 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.","aliases":["GHSA-8fvw-xrgv-jq4w"],"modified":"2026-11-01T02:31:03.824830840Z","published":"2026-10-23T04:04:02.426Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-400","CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86019.json"},"references":[{"type":"WEB","url":"https://github.com/Part-DB/Part-DB-server/releases/tag/v2.13.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86019.json"},{"type":"ADVISORY","url":"https://github.com/Part-DB/Part-DB-server/security/advisories/GHSA-8fvw-xrgv-jq4w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-86019"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/part-db/part-db-server","events":[{"introduced":"0"},{"fixed":"1a8ff831ab5a1135a3f8193e895c424596530051"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"2.13.2"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"original_tag":"v2.13.2","range":[{"fixed":"1a8ff831ab5a1135a3f8193e895c424596530051"}],"source":"REFERENCES_TAG"},{"range":[{"introduced":"0"},{"fixed":"2.13.2"}],"source":"DESCRIPTION"}]}}],"versions":["v2.13.0","v2.12.2","v2.12.1","v2.12.0","v2.11.1","v2.11.0","v2.10.0","v2.9.1","v2.9.0","v2.8.1","v2.8.0","v2.7.1","v2.7.0","v2.6.0","v2.5.1","v2.5.0","v2.4.0","v2.3.0","v2.2.1","v2.2.0","v2.1.2","v2.1.0","v2.1.1","v2.0.2","v2.0.1","v2.0.0","v1.17.4","v1.17.3","v1.17.2","v1.17.1","v1.17.0","v1.16.1","v1.16.0","v1.15.2","v1.15.1","v1.15.0","v1.14.5","v1.12.1","v1.12.0","v1.11.3","v1.11.2","v1.11.1","v1.11.0","v1.10.7","v1.10.6","v1.10.5","v1.10.4","v1.10.3","v1.10.2","v1.10.1","v1.10.0","v1.9.1","v1.9.0","v1.8.2","v1.8.1","v1.8.0","v1.7.3","v1.7.2","v1.7.1","v1.7.0","v1.6.1","v1.6.0","v1.5.2","v1.5.1","v1.5.0","v1.4.2","v1.4.1","v1.4.0","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.0","v1.1.1","v1.1.0","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v1.0.0-beta.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-86019.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
