Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-65660 in the wild since at least 25 Sep 2026.\n\nAffected product: Microsoft Sharepoint Server. 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-2026-65660/ (Markdown: https://insights.sbomify.com/CVE-2026-65660/index.md)","id":"CVE-2026-65660","markdown":"https://insights.sbomify.com/CVE-2026-65660/index.md","name":"CVE-2026-65660","record":{"aliases":["GHSA-r94x-x846-rxqx"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SharePoint Server","requires_auth":"low_privilege","summary":"An authorized attacker can execute arbitrary code remotely on Microsoft SharePoint Server via improper code generation control.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"sharepoint_server","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Improper control of generation of code ('code injection') in Microsoft Office SharePoint allows an authorized attacker to execute code over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-09-25","github_poc":2,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-25T20:27:27Z","kind":"github_poc","ref":"https://github.com/ShadowForge-Cyber/CVE-2026-65660-Poc","stars":1,"title":"Malicious Register Directive Code Injection Exploit"},{"date":"2026-09-25T03:22:53Z","kind":"github_poc","ref":"https://github.com/HORKimhab/CVE-2026-65660","stars":0,"title":"CVE-2026-65660 - Draft or TODO"}],"tier":"exploited"},"has_fix":null,"headline":"Microsoft SharePoint Code Injection","id":"CVE-2026-65660","indexable":true,"kev":{"dateAdded":"2026-09-25","dueDate":"2026-09-28","knownRansomwareCampaignUse":"Unknown","product":"SharePoint","requiredAction":"Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes).
