KG JUNG Smart Visu Server, published on 12 Feb 2026. An attacker can exploit it over the internet without logging in, 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-2026-26234 exists.\n\nAffected product: ALBRECHT JUNG GMBH \u0026 CO. KG JUNG Smart Visu 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-2026-26234/ (Markdown: https://insights.sbomify.com/CVE-2026-26234/index.md)","id":"CVE-2026-26234","markdown":"https://insights.sbomify.com/CVE-2026-26234/index.md","name":"CVE-2026-26234","record":{"aliases":["GHSA-9f79-6fpr-26f7"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["security_bypass","other"],"network_reachable":"yes","non_default_config":false,"product_category":"Smart Visu Server","requires_auth":"none","summary":"Unauthenticated attackers can manipulate X-Forwarded-Host headers to redirect users to malicious domains, enabling phishing and cache poisoning attacks.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"smart_visu_server_firmware","vendor":"jung-group"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-644","name":"Improper Neutralization of HTTP Headers for Scripting Syntax"}],"description":"JUNG Smart Visu Server 1.1.1050 contains a request header manipulation vulnerability that allows unauthenticated attackers to override request URLs by injecting arbitrary values in the X-Forwarded-Host header.
