Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-21997 in the wild and no public exploit code.\n\nAffected product: Oracle Life Sciences Empirica Signal. 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-2026-21997/ (Markdown: https://insights.sbomify.com/CVE-2026-21997/index.md)","id":"CVE-2026-21997","markdown":"https://insights.sbomify.com/CVE-2026-21997/index.md","name":"CVE-2026-21997","record":{"aliases":["GHSA-fjgq-vg76-2mmp"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Life Sciences Signal","requires_auth":"low_privilege","summary":"Low-privileged attackers can modify or read critical data in Oracle Life Sciences Empirica Signal via HTTP due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"life_sciences_empirica_signal","vendor":"oracle"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Vulnerability in the Oracle Life Sciences Empirica Signal product of Oracle Life Science Applications (component: Common Core).
