No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-86018/ (Markdown: https://insights.sbomify.com/CVE-2026-86018/index.md)","id":"CVE-2026-86018","markdown":"https://insights.sbomify.com/CVE-2026-86018/index.md","name":"CVE-2026-86018","record":{"aliases":["GHSA-2whx-2cx7-qvq6"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Part-DB: Authenticated Disk Exhaustion via Unbounded Server-Side Attachment Downloads","id":"CVE-2026-86018","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Part-DB: Attachment Size Limit Bypass via API Base64 Upload","id":"CVE-2026-86019"},"packages":[],"prev":{"headline":"VNote: Stored XSS via YAML Frontmatter Leading to Local File Read and Remote Exfiltration","id":"CVE-2026-86016"},"products":["Part-DB-server"],"published":"2026-10-23","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["Part-DB"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-86018/"}
