Altec DocLink, published on 24 Feb 2026. 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-2026-26222 in the wild and no public exploit code.\n\nAffected product: Beyond Limits Inc. Altec DocLink. 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-2026-26222/ (Markdown: https://insights.sbomify.com/CVE-2026-26222/index.md)","id":"CVE-2026-26222","markdown":"https://insights.sbomify.com/CVE-2026-26222/index.md","name":"CVE-2026-26222","record":{"aliases":["GHSA-gfvx-3cf3-5x6x"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Altec DocLink","requires_auth":"none","summary":"Unauthenticated attackers can exploit insecure .NET Remoting endpoints to read arbitrary files, write files, and achieve remote code execution.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"altec_doclink","vendor":"beyond"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Altec DocLink (now maintained by Beyond Limits Inc.) version 4.0.336.0 exposes insecure .NET Remoting endpoints over TCP and HTTP/SOAP via Altec.RDCHostService.exe using the ObjectURI \"doclinkServer.soap\". The service does not require authentication and is vulnerable to unsafe object unmarshalling, allowing remote attackers to read arbitrary files from the underlying system by specifying local file paths. Additionally, attackers can coerce SMB authentication via UNC paths and write arbitrary files to server locations. Because writable paths may be web-accessible under IIS, this can result in unauthenticated remote code execution or denial of service through file overwrite.","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":"DocLink .NET Remoting Unauthenticated Arbitrary File Read/Write RCE","id":"CVE-2026-26222","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"SPIP \u003c 4.4.8 Cross-Site Scripting via Iframe Tags in Private Area","id":"CVE-2026-26223"},"packages":[],"prev":{"headline":"Hyland OnBase Timer Service Unauthenticated .NET Remoting RCE","id":"CVE-2026-26221"},"products":["Altec DocLink"],"published":"2026-02-24","related":[],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-27","vendors":["Beyond Limits Inc."]},"summary":"Unauthenticated attackers can exploit insecure .NET Remoting endpoints to read arbitrary files, write files, and achieve remote code execution.","url":"https://insights.sbomify.com/CVE-2026-26222/"}
