Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-55775 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 0.0.0-20260617103935-d3c1cc64b1ae\n- github.com/openbao/openbao (Go): affected all versions; fixed in 0.0.0-20260617103935-d3c1cc64b1ae\n- github.com/openbao/openbao (Go): affected all versions; fixed in 0.0.0-20260617103935-d3c1cc64b1ae\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-2026-55775/ (Markdown: https://insights.sbomify.com/CVE-2026-55775/index.md)","id":"CVE-2026-55775","markdown":"https://insights.sbomify.com/CVE-2026-55775/index.md","name":"CVE-2026-55775","record":{"aliases":["BIT-openbao-2026-55775","GHSA-mwr2-wmgp-crj6","GO-2026-5517"],"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":"low_privilege","summary":"Attackers with specific namespace capabilities can bypass ACL checks to modify or delete the containing namespace's configuration.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"OpenBao is an open source identity-based secrets management system. Prior to 2.5.5, OpenBao users granted capabilities on /sys/namespaces/root within a non-root namespace could exploit special handling of the literal root path in namespace canonicalization. The /sys/namespaces/* endpoint family can resolve its containing namespace through a path prefix or X-Vault-Namespace header. ACL checks occurred before root canonicalized to an empty path, causing /sys/namespaces/root to resolve to the system backend's containing namespace and allowing permitted lookups, deletion, locking, or custom metadata changes against that direct containing namespace. The root namespace and arbitrary unrelated namespaces are not affected, and available operations depend on the capabilities granted on the path and subpaths such as /api-lock. This issue is fixed in version 2.5.5.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"OpenBao's System Backend allows Unauthorized Management of the containing Namespace","id":"CVE-2026-55775","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":6,"n_references":7,"next":{"headline":"OpenBao: Transit secrets engine crashes on key creation with `derived: true` for asymmetric key types","id":"CVE-2026-55776"},"packages":[{"ecosystem":"Bitnami","fixed":["2.5.5"],"introduced":["0"],"last_affected":[],"package":"openbao","purl":"pkg:bitnami/openbao","source":"BIT-openbao-2026-55775"},{"ecosystem":"Go","fixed":["0.0.0-20260617103935-d3c1cc64b1ae"],"introduced":["0","0.1.0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","source":"GO-2026-5517"},{"ecosystem":"Go","fixed":["0.0.0-20260617103935-d3c1cc64b1ae"],"introduced":["0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":null,"source":"GHSA-mwr2-wmgp-crj6"},{"ecosystem":"Go","fixed":["0.0.0-20260617103935-d3c1cc64b1ae"],"introduced":["0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","source":"GHSA-mwr2-wmgp-crj6"},{"ecosystem":"Go","fixed":[],"introduced":["0.1.0"],"last_affected":["2.5.4"],"package":"github.com/openbao/openbao","purl":null,"source":"GHSA-mwr2-wmgp-crj6"},{"ecosystem":"Go","fixed":[],"introduced":["0.1.0"],"last_affected":["2.5.4"],"package":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","source":"GHSA-mwr2-wmgp-crj6"}],"prev":{"headline":"OpenBao: Cross-namespace lease revocation/renewal via canonical sys/leases/{revoke,renew} — incomplete fix of CVE-2026-45808","id":"CVE-2026-55774"},"products":["openbao"],"published":"2026-09-15","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-15","vendors":["openbao"]},"summary":"Attackers with specific namespace capabilities can bypass ACL checks to modify or delete the containing namespace's configuration.","url":"https://insights.sbomify.com/CVE-2026-55775/"}
