Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-21790 in the wild and no public exploit code.\n\nAffected product: HCLSoftware Traveler. 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-2026-21790/ (Markdown: https://insights.sbomify.com/CVE-2026-21790/index.md)","id":"CVE-2026-21790","markdown":"https://insights.sbomify.com/CVE-2026-21790/index.md","name":"CVE-2026-21790","record":{"aliases":["GHSA-mr94-p7f2-xw23"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"HCL Traveler","requires_auth":"low_privilege","summary":"Attackers can bypass authentication checks in HCL Traveler due to weak default HTTP header validation.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HCL","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"HCL Traveler is susceptible to a weak default HTTP header validation vulnerability, which could allow an attacker to bypass additional authentication checks.","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 Traveler is susceptible to a weak default HTTP header validation vulnerability","id":"CVE-2026-21790","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"HCL Sametime for Android is affected by sensitive information disclosure","id":"CVE-2026-21791"},"packages":[],"prev":{"headline":"HCL Connections is vulnerable to broken access control","id":"CVE-2026-21789"},"products":["Traveler"],"published":"2026-03-24","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":"2026-03-24","vendors":["HCLSoftware"]},"summary":"Attackers can bypass authentication checks in HCL Traveler due to weak default HTTP header validation.","url":"https://insights.sbomify.com/CVE-2026-21790/"}
