Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-21837 in the wild and no public exploit code.\n\nAffected product: HCLSoftware Digital Experience. 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-2026-21837/ (Markdown: https://insights.sbomify.com/CVE-2026-21837/index.md)","id":"CVE-2026-21837","markdown":"https://insights.sbomify.com/CVE-2026-21837/index.md","name":"CVE-2026-21837","record":{"aliases":["GHSA-89jh-pgw9-qrmm"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"HCL Digital Experience","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary OS commands via the Digital Asset Management API, potentially leading to system takeover.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HCL","cpe":[{"product":"digital_experience","vendor":"hcltech"},{"product":"digital_experience_compose","vendor":"hcltech"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"HCL Digital Experience is affected by an OS command injection vulnerability in the Digital Asset Management API.  An attacker may execute arbitrary operating system commands, typically inheriting the privileges of the vulnerable application, which could possibly lead to a complete system takeover and data compromise.","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 Digital Experience is affected by an OS command injection vulnerability in the Digital Asset Management API","id":"CVE-2026-21837","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"HCL BigFix Platform is affected by a user enumeration vulnerability","id":"CVE-2026-21840"},"packages":[],"prev":{"headline":"HCL DominoIQ is affected by broken access control","id":"CVE-2026-21836"},"products":["Digital Experience"],"published":"2026-06-05","related":[{"cvss_score":9.3,"headline":"HCL Digital Experience is susceptible to cross site scripting (XSS)","id":"CVE-2023-37538","kev_date_added":null,"published":"2023-10-11"},{"cvss_score":7.5,"headline":"HCL Digital Experience 9.5 containers include vulnerabilities that could expose sensitive data to unauthorized parties via crafted requests.","id":"CVE-2020-14255","kev_date_added":null,"published":"2021-02-02"},{"cvss_score":6.1,"headline":"HCL Digital Experience Compose is affected by a reflected cross-site scripting (XSS) vulnerability in the search center","id":"CVE-2026-21825","kev_date_added":null,"published":"2026-06-05"},{"cvss_score":6.1,"headline":"HCL Digital Experience and HCL Digital Experience Compose could be susceptible to Host header injection","id":"CVE-2026-21826","kev_date_added":null,"published":"2026-06-05"},{"cvss_score":6.1,"headline":"HCL Digital Experience is susceptible to stored cross-site scripting (XSS)","id":"CVE-2025-62326","kev_date_added":null,"published":"2026-02-20"},{"cvss_score":6.1,"headline":"Cross-site scripting in HCL Digital Experience","id":"CVE-2020-4081","kev_date_added":null,"published":"2021-02-02"}],"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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-09","vendors":["HCLSoftware"]},"summary":"Attackers can execute arbitrary OS commands via the Digital Asset Management API, potentially leading to system takeover.","url":"https://insights.sbomify.com/CVE-2026-21837/"}
