An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20538 in the wild and no public exploit code.\n\nAffected product: Ibm Cloud Pak for Security. 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-2021-20538/ (Markdown: https://insights.sbomify.com/CVE-2021-20538/index.md)","id":"CVE-2021-20538","markdown":"https://insights.sbomify.com/CVE-2021-20538/index.md","name":"CVE-2021-20538","record":{"aliases":["GHSA-r4xw-2898-q2r3"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Cloud Pak for Security","requires_auth":"none","summary":"Incorrect authorization mechanisms in IBM Cloud Pak for Security allow users to access sensitive information or perform unauthorized actions.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"cloud_pak_for_security","vendor":"ibm"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.0/I:L/PR:N/AC:H/AV:N/S:U/C:L/UI:N/A:N/E:U/RL:O/RC:C","version":"3.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"IBM Cloud Pak for Security (CP4S) 1.5.0.0 and 1.5.0.1 could allow a user to obtain sensitive information or perform actions they should not have access to due to incorrect authorization mechanisms.
