It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-20411 and fix it if it is affected.\n\nWhat it is: CVE-2021-20411 is a high-severity authentication bypass vulnerability in IBM Security Verify Information Queue, published on 12 Feb 2021. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-20411 in the wild and no public exploit code.\n\nAffected product: IBM Security Verify Information Queue. 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-2021-20411/ (Markdown: https://insights.sbomify.com/CVE-2021-20411/index.md)","id":"CVE-2021-20411","markdown":"https://insights.sbomify.com/CVE-2021-20411/index.md","name":"CVE-2021-20411","record":{"aliases":["GHSA-php9-88rp-7qwr"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM Security Verify","requires_auth":"none","summary":"Attackers can impersonate other users due to incorrect session identifier updates in IBM Security Verify Information Queue.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"security_verify_information_queue","vendor":"ibm"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/S:C/AV:A/PR:N/C:H/UI:R/I:H/A:N/AC:H/E:U/RL:O/RC:C","version":"3.0"},"cwes":[{"id":"CWE-669","name":"Incorrect Resource Transfer Between Spheres"}],"description":"IBM Security Verify Information Queue 1.0.6 and 1.0.7 could allow a user to impersonate another user on the system due to incorrectly updating the session identifier.
