Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-21783 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-2026-21783/ (Markdown: https://insights.sbomify.com/CVE-2026-21783/index.md)","id":"CVE-2026-21783","markdown":"https://insights.sbomify.com/CVE-2026-21783/index.md","name":"CVE-2026-21783","record":{"aliases":["GHSA-w3p4-547j-v9cv"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"HCL Traveler","requires_auth":"low_privilege","summary":"HCL Traveler exposes sensitive system details in error messages, allowing attackers to gather intelligence for targeted attacks.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HCL","cpe":[{"product":"traveler","vendor":"hcltech"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-209","name":"Generation of Error Message Containing Sensitive Information"}],"description":"HCL Traveler is affected by sensitive information disclosure.  The application generates some error messages that provide detailed information about errors and failures, such as internal paths, file names, sensitive tokens, credentials, error codes, or stack traces.  Attackers could exploit this information to gain insights into the system's architecture and potentially launch targeted attacks.","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 affected by sensitive information disclosure","id":"CVE-2026-21783","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"HCL IntelliOps Event Management is affected by multiple security vulnerabilities.","id":"CVE-2026-21784"},"packages":[],"prev":{"headline":"HCL Traveler for Microsoft Outlook (HTMO) is susceptible to DLL hijacking","id":"CVE-2026-21770"},"products":["Traveler"],"published":"2026-03-24","related":[{"cvss_score":7.5,"headline":"HCL Traveler is susceptible to a Reflected Cross-Site Scripting vulnerability in the web admin (LotusTraveler.nsf)","id":"CVE-2022-27561","kev_date_added":null,"published":"2022-09-15"},{"cvss_score":5.4,"headline":"Cross-site scripting in HCL Traveler","id":"CVE-2019-4409","kev_date_added":null,"published":"2019-10-18"},{"cvss_score":4.9,"headline":"Cross-site scripting in HCL Traveler","id":"CVE-2021-27778","kev_date_added":null,"published":"2022-05-31"},{"cvss_score":4.3,"headline":"An internal path disclosure vulnerability affects HCL Traveler","id":"CVE-2025-0278","kev_date_added":null,"published":"2025-04-03"},{"cvss_score":4.3,"headline":"HCL Traveler is affected by generation of error messages containing sensitive information","id":"CVE-2025-0279","kev_date_added":null,"published":"2025-04-03"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-03-24","vendors":["HCLSoftware"]},"summary":"HCL Traveler exposes sensitive system details in error messages, allowing attackers to gather intelligence for targeted attacks.","url":"https://insights.sbomify.com/CVE-2026-21783/"}
