An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-55774 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/openbao/openbao (Go): affected all versions; fixed in 0.0.0-20260617103932-b20b999dd404\n- github.com/openbao/openbao (Go): affected all versions; fixed in 0.0.0-20260617103932-b20b999dd404\n- github.com/openbao/openbao (Go): affected all versions; fixed in 0.0.0-20260617103932-b20b999dd404\n- github.com/openbao/openbao (Go): affected from 0.1.0 up to 2.5.4; no fix listed\n- github.com/openbao/openbao (Go): affected from 0.1.0 up to 2.5.4; no fix listed\n- openbao (Bitnami): affected all versions; fixed in 2.5.5\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-2026-55774/ (Markdown: https://insights.sbomify.com/CVE-2026-55774/index.md)","id":"CVE-2026-55774","markdown":"https://insights.sbomify.com/CVE-2026-55774/index.md","name":"CVE-2026-55774","record":{"aliases":["BIT-openbao-2026-55774","GHSA-c36x-h252-g9x2","GO-2026-5304"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenBao secrets manager","requires_auth":"high_privilege","summary":"An attacker in one namespace can revoke leases in another namespace by knowing the lease ID, bypassing isolation and revoking credentials.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":2.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"OpenBao is an open source identity-based secrets management system. Prior to 2.5.5, an OpenBao user with access to sys/leases/revoke/:lease_id in one namespace could revoke a lease in another namespace when the foreign lease_id was known, bypassing namespace ACL isolation. The affected lease lookup routing in vault/expiration.go allowed FetchLeaseInfo and loadEntry to resolve cached or stored lease data outside the request namespace, allowing a tenant that intentionally disclosed a lease identifier to have the lease and its underlying credential revoked by another tenant.
