Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-66834 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-2025-66834/ (Markdown: https://insights.sbomify.com/CVE-2025-66834/index.md)","id":"CVE-2025-66834","markdown":"https://insights.sbomify.com/CVE-2025-66834/index.md","name":"CVE-2025-66834","record":{"aliases":["GHSA-5vw2-j3g7-v489"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TrueConf Server","requires_auth":"low_privilege","summary":"A normal user can inject malicious spreadsheet formulas into exported chat logs via crafted Display Name, potentially leading to code execution when logs are opened.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"trueconf_server","vendor":"trueconf"}],"cvss":{"score":7.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-1236","name":"Improper Neutralization of Formula Elements in a CSV File"}],"description":"A CSV Formula Injection vulnerability in TrueConf Server v5.5.2.10813 allows a normal user to inject malicious spreadsheet formulas into exported chat logs via crafted Display Name.","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-2025-66834","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Other in n/a","id":"CVE-2025-66835"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2025-66824"},"products":["n/a"],"published":"2025-12-30","related":[{"cvss_score":9.5,"headline":"TrueConf Server Code Injection","id":"CVE-2026-72530","kev_date_added":"2026-08-20","published":"2026-08-19"},{"cvss_score":9.3,"headline":"TrueConf Server Missing Authentication for Critical Function","id":"CVE-2026-72529","kev_date_added":"2026-08-20","published":"2026-08-19"},{"cvss_score":7.3,"headline":"Cross-site scripting in n/a","id":"CVE-2025-66824","kev_date_added":null,"published":"2025-12-30"},{"cvss_score":4.3,"headline":"TrueConf Server cross-site request forgery","id":"CVE-2017-20120","kev_date_added":null,"published":"2022-06-29"},{"cvss_score":3.5,"headline":"Cross-site scripting in n/a","id":"CVE-2025-66823","kev_date_added":null,"published":"2025-12-30"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"total"},"state":"PUBLISHED","updated":"2026-01-02","vendors":["n/a"]},"summary":"A normal user can inject malicious spreadsheet formulas into exported chat logs via crafted Display Name, potentially leading to code execution when logs are opened.","url":"https://insights.sbomify.com/CVE-2025-66834/"}
