An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-88405 exists.\n\nAffected product: n/a. 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-2026-88405/ (Markdown: https://insights.sbomify.com/CVE-2026-88405/index.md)","id":"CVE-2026-88405","markdown":"https://insights.sbomify.com/CVE-2026-88405/index.md","name":"CVE-2026-88405","record":{"aliases":["GHSA-c4rf-xpw9-chfc"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Univer spreadsheet library","requires_auth":"none","summary":"Attackers can execute arbitrary code in Univer via a crafted payload in the remote register function service.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"A remote code execution (RCE) vulnerability in the RemoteRegisterFunctionService function (/remote/remote-register-function.service.ts) of Univer v1.0.0-alpha.2 allows attackers to execute arbitrary code via a crafted payload.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Code injection in n/a","id":"CVE-2026-88405","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2026-88406"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2026-88404"},"products":["n/a"],"published":"2026-09-21","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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-24","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code in Univer via a crafted payload in the remote register function service.","url":"https://insights.sbomify.com/CVE-2026-88405/"}
