An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-7858 in the wild and no public exploit code.\n\nAffected product: Dassault Systèmes Magic Collaboration Studio. 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-2026-7858/ (Markdown: https://insights.sbomify.com/CVE-2026-7858/index.md)","id":"CVE-2026-7858","markdown":"https://insights.sbomify.com/CVE-2026-7858/index.md","name":"CVE-2026-7858","record":{"aliases":["GHSA-wpwx-h3fg-2jh5"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Modeling collaboration server","requires_auth":"none","summary":"Unauthenticated attackers can achieve remote code execution via unsafe deserialization in Teamwork Cloud and Magic Collaboration Studio.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"3DS","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-502","name":"Deserialization of Untrusted Data"}],"description":"A Deserialization of Untrusted Data vulnerability affecting Teamwork Cloud from No Magic Release 2022x through No Magic Release 2026x and Magic Collaboration Studio from CATIA Magic Release 2022x through CATIA Magic Release 2026x could lead to an unauthenticated remote code execution.","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":"Deserialization in Magic Collaboration Studio","id":"CVE-2026-7858","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Motors Car Dealership \u0026 Classified Listings \u003c 1.4.110 - Unauthenticated Post-Meta Write via stm_ajax_add_a_car_media","id":"CVE-2026-7859"},"packages":[],"prev":{"headline":"D-Link DI-8100 CGI user_group.asp sprintf buffer overflow","id":"CVE-2026-7857"},"products":["Magic Collaboration Studio","Teamwork Cloud - Business Edition","Teamwork Cloud - Business Pro Edition","Teamwork Cloud - Enterprise Edition","Teamwork Cloud - Standard Edition"],"published":"2026-06-01","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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-01","vendors":["Dassault Systèmes"]},"summary":"Unauthenticated attackers can achieve remote code execution via unsafe deserialization in Teamwork Cloud and Magic Collaboration Studio.","url":"https://insights.sbomify.com/CVE-2026-7858/"}
