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-2026-123973/ (Markdown: https://insights.sbomify.com/CVE-2026-123973/index.md)","id":"CVE-2026-123973","markdown":"https://insights.sbomify.com/CVE-2026-123973/index.md","name":"CVE-2026-123973","record":{"aliases":["GHSA-6m28-hpgh-m3mr"],"analysis":null,"analysis_generated_by":null,"assigner":"mitre","cpe":[],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"SharePoint Products CopyMove before 2026-11-06 allows traversal. An authenticated SharePoint user with the necessary permissions to use the ZIP import functionality may exploit a path traversal vulnerability in CopyMove for SharePoint 2019 and CopyMove for SharePoint V6 by supplying a crafted ZIP archive. A path traversal vulnerability in the ZIP import functionality of SharePoint Products ApS CopyMove for SharePoint 2019 and CopyMove for SharePoint V6 allows a user with access to the ZIP import functionality to supply a crafted ZIP archive containing malicious entry paths. During extraction, these paths may cause files to be written outside the intended extraction directory. The issue has been addressed by implementing ZIP archive entry path validation to prevent extraction outside the designated directory.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"SharePoint Products CopyMove before 2026-11-06 allows traversal.","id":"CVE-2026-123973","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"pytorch/serve: Local privilege escalation through insecure temporary path","id":"CVE-2026-123974"},"nickname":null,"packages":[],"prev":{"headline":"Tenda AC19 saveParentControlInfo heap-based overflow","id":"CVE-2026-123966"},"products":["CopyMove for SharePoint 2019","CopyMove for SharePoint V6"],"published":"2026-11-06","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-11-09","vendors":["SharePoint Products"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-123973/"}
