{"id":"CVE-2026-86019","state":"PUBLISHED","title":"Part-DB: Attachment Size Limit Bypass via API Base64 Upload","description":"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.","publishedAt":"2026-10-23T04:04:02.426Z","updatedAt":"2026-10-30T16:29:23.553Z","severity":{"score":5.3,"label":"Medium","version":"4.0","vector":"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","source":"GitHub_M"},"assigner":"GitHub_M","products":["Part-DB Part-DB-server"],"affected":[{"vendor":"Part-DB","product":"Part-DB-server","versions":[{"version":"< 2.13.2","status":"affected"}]}],"references":["https://github.com/Part-DB/Part-DB-server/security/advisories/GHSA-8fvw-xrgv-jq4w","https://github.com/Part-DB/Part-DB-server/releases/tag/v2.13.2"],"weaknesses":["CWE-400","CWE-770"],"ingestedAt":"2026-10-30T16:34:06.595Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/86xxx/CVE-2026-86019.json","commit":"9e54b3557627dfb3a1074c39eb8411c2987ff251","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-86019","state":"PUBLISHED","datePublished":"2026-10-23T04:04:02.426Z","dateUpdated":"2026-10-30T16:29:23.553Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-09-04T19:23:40.691Z"},"containers":{"cna":{"title":"Part-DB: Attachment Size Limit Bypass via API Base64 Upload","descriptions":[{"lang":"en","value":"Part-DB is an open source inventory management system for electronic components.
