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-2011-4076 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nova (PyPI): affected all versions; fixed in 12.0.0a0\n- nova (PyPI): affected all versions; fixed in 12.0.0a0\n- nova (PyPI): affected all versions; fixed in 12.0.0a0\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-2011-4076/ (Markdown: https://insights.sbomify.com/CVE-2011-4076/index.md)","id":"CVE-2011-4076","markdown":"https://insights.sbomify.com/CVE-2011-4076/index.md","name":"CVE-2011-4076","record":{"aliases":["DEBIAN-CVE-2011-4076","GHSA-vcmv-6rxx-fh7r","PYSEC-2026-691"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenStack Nova","requires_auth":"none","summary":"Attackers can obtain EC2 secret keys by accessing or brute-forcing EC2 access keys, leading to credential exposure and potential account takeover in OpenStack Nova.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"nova","vendor":"openstack"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"OpenStack Nova before 2012.1 allows someone with access to an EC2_ACCESS_KEY (equivalent to a username) to obtain the EC2_SECRET_KEY (equivalent to a password).
