An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-21827 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-2026-21827/ (Markdown: https://insights.sbomify.com/CVE-2026-21827/index.md)","id":"CVE-2026-21827","markdown":"https://insights.sbomify.com/CVE-2026-21827/index.md","name":"CVE-2026-21827","record":{"aliases":["GHSA-xq3v-phjg-8r8x"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"HCL Connections","requires_auth":"none","summary":"An attacker can obtain sensitive information they are not entitled to due to improper handling of request data in HCL Connections.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HCL","cpe":[],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-359","name":"Exposure of Private Personal Information to an Unauthorized Actor"}],"description":"HCL Connections is vulnerable to an information disclosure vulnerability which could allow a user to obtain sensitive information they are not entitled to, caused by improper handling of request data they are not entitled to, caused by improper handling of request data.","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 an information disclosure vulnerability","id":"CVE-2026-21827","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 BigFix AEX is affected by multiple security vulnerabilities.","id":"CVE-2026-21830"},"packages":[],"prev":{"headline":"HCL Digital Experience and HCL Digital Experience Compose could be susceptible to Host header injection","id":"CVE-2026-21826"},"products":["Connections"],"published":"2026-08-31","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":"2026-09-01","vendors":["HCLSoftware"]},"summary":"An attacker can obtain sensitive information they are not entitled to due to improper handling of request data in HCL Connections.","url":"https://insights.sbomify.com/CVE-2026-21827/"}
