An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-21785 in the wild and no public exploit code.\n\nAffected product: HCLSoftware BigFix Remote Control 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-2026-21785/ (Markdown: https://insights.sbomify.com/CVE-2026-21785/index.md)","id":"CVE-2026-21785","markdown":"https://insights.sbomify.com/CVE-2026-21785/index.md","name":"CVE-2026-21785","record":{"aliases":["GHSA-6x6f-pfq2-m75m"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Remote Control Server","requires_auth":"high_privilege","summary":"Attackers can bypass Content Security Policy restrictions to load unauthorized resources in HCL BigFix Remote Control Server WebUI.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HCL","cpe":[],"cvss":{"score":4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-1021","name":"Improper Restriction of Rendered UI Layers or Frames"}],"description":"A misconfigured Content Security Policy (CSP) in HCL BigFix Remote Control Server WebUI (versions 10.1.0.0442 and earlier) fails to define directives without fallbacks, allowing attackers to bypass intended security restrictions and load unauthorized resources.","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":"HCL BigFix Remote Control Server WebUI is affected by a misconfigured Content Security Policy","id":"CVE-2026-21785","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"HCL Sametime for iOS is affected by sensitive information disclosure","id":"CVE-2026-21786"},"packages":[],"prev":{"headline":"HCL IntelliOps Event Management is affected by multiple security vulnerabilities.","id":"CVE-2026-21784"},"products":["BigFix Remote Control Server"],"published":"2026-05-27","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-28","vendors":["HCLSoftware"]},"summary":"Attackers can bypass Content Security Policy restrictions to load unauthorized resources in HCL BigFix Remote Control Server WebUI.","url":"https://insights.sbomify.com/CVE-2026-21785/"}
