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-2021-27760 in the wild and no public exploit code.\n\nAffected product: HCL Notes. 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-2021-27760/ (Markdown: https://insights.sbomify.com/CVE-2021-27760/index.md)","id":"CVE-2021-27760","markdown":"https://insights.sbomify.com/CVE-2021-27760/index.md","name":"CVE-2021-27760","record":{"aliases":["GHSA-xcf3-q63w-pqpj"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"HCL Notes client","requires_auth":"low_privilege","summary":"An authenticated user can execute arbitrary JavaScript code on another user's HCL Notes client via a specially crafted chat message.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HCL","cpe":[{"product":"hcl_inotes","vendor":"hcltech"}],"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:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"An issue was discovered in the Sametime chat feature in the Notes 11.0 - 11.0.1 FP4 clients.
