An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-1991 in the wild and no public exploit code.\n\nAffected product: Ibm Api Connect. 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-2018-1991/ (Markdown: https://insights.sbomify.com/CVE-2018-1991/index.md)","id":"CVE-2018-1991","markdown":"https://insights.sbomify.com/CVE-2018-1991/index.md","name":"CVE-2018-1991","record":{"aliases":["GHSA-84jp-rqr8-mw8v"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"API management platform","requires_auth":"high_privilege","summary":"Attackers can obtain sensitive software stack details from CMC UI headers, aiding further reconnaissance against IBM API Connect deployments.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"api_connect","vendor":"ibm"}],"cvss":{"score":2.7,"severity":"low","source":"cna","vector":"CVSS:3.0/A:N/S:U/PR:H/AV:N/C:L/I:N/UI:N/AC:L/RC:C/RL:O/E:U","version":"3.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"IBM API Connect 5.0.0.0, and 5.0.8.6 could could return sensitive information that could provide critical information as to the underlying software stack in CMC UI headers.
