Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-33551 exists.\n\nAffected packages and fixed versions:\n- keystone (PyPI): affected from 14.0.0; fixed in 26.1.1\n- keystone (PyPI): affected from 14.0.0; fixed in 26.1.1\n- keystone (PyPI): affected from 14.0.0; fixed in 26.1.1\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-2026-33551/ (Markdown: https://insights.sbomify.com/CVE-2026-33551/index.md)","id":"CVE-2026-33551","markdown":"https://insights.sbomify.com/CVE-2026-33551/index.md","name":"CVE-2026-33551","record":{"aliases":["DEBIAN-CVE-2026-33551","GHSA-4phw-6824-6cfp","PYSEC-2026-202"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenStack Keystone","requires_auth":"low_privilege","summary":"Authenticated users with reader roles can bypass application credential restrictions to obtain full S3 permissions via the EC2 API.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"keystone","vendor":"openstack"}],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"An issue was discovered in OpenStack Keystone 14 through 26 before 26.1.1, 27.0.0, 28.0.0, and 29.0.0.
