An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-21766 in the wild and no public exploit code.\n\nAffected product: HCLSoftware HCL Digital Experience and Digital Experience Compose. 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-2026-21766/ (Markdown: https://insights.sbomify.com/CVE-2026-21766/index.md)","id":"CVE-2026-21766","markdown":"https://insights.sbomify.com/CVE-2026-21766/index.md","name":"CVE-2026-21766","record":{"aliases":["GHSA-vjj9-w76c-7q84"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"HCL Digital Experience","requires_auth":"high_privilege","summary":"Attackers can read sensitive credentials from web server logs if specific configurations are used with the default login portlet.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HCL","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-532","name":"Insertion of Sensitive Information into Log File"},{"id":"CWE-522","name":"Insufficiently Protected Credentials"}],"description":"The default login portlet in HCL Digital Experience and Digital Experience Compose insufficiently protects credentials.  Under certain very specific use cases and specific configurations, sensitive information may be written to web server logs.  This only affects applications using the default login portlet.","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 and Digital Experience Compose insufficiently protects credentials","id":"CVE-2026-21766","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 Platform is affected by insufficient authentication","id":"CVE-2026-21767"},"packages":[],"prev":{"headline":"HCL BigFix Platform is affected by insecure permissions on private cryptographic keys","id":"CVE-2026-21765"},"products":["HCL Digital Experience and Digital Experience Compose"],"published":"2026-08-05","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":"2026-08-06","vendors":["HCLSoftware"]},"summary":"Attackers can read sensitive credentials from web server logs if specific configurations are used with the default login portlet.","url":"https://insights.sbomify.com/CVE-2026-21766/"}
