Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-21789 in the wild and no public exploit code.\n\nAffected product: HCLSoftware Connections. 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-2026-21789/ (Markdown: https://insights.sbomify.com/CVE-2026-21789/index.md)","id":"CVE-2026-21789","markdown":"https://insights.sbomify.com/CVE-2026-21789/index.md","name":"CVE-2026-21789","record":{"aliases":["GHSA-hx5c-g9jj-chxv"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"HCL Connections","requires_auth":"low_privilege","summary":"An unauthorized user can update data in HCL Connections due to broken access control, requiring administrators to apply vendor patches.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HCL","cpe":[],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"HCL Connections contains a broken access control vulnerability that may allow unauthorized user to update data in certain scenarios.","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 Connections is vulnerable to broken access control","id":"CVE-2026-21789","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"HCL Traveler is susceptible to a weak default HTTP header validation vulnerability","id":"CVE-2026-21790"},"packages":[],"prev":{"headline":"HCL Connections is vulnerable to cross-site scripting (XSS)","id":"CVE-2026-21788"},"products":["Connections"],"published":"2026-05-18","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":"2026-05-18","vendors":["HCLSoftware"]},"summary":"An unauthorized user can update data in HCL Connections due to broken access control, requiring administrators to apply vendor patches.","url":"https://insights.sbomify.com/CVE-2026-21789/"}
