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-2026-46405 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/openbao/openbao (Go): affected all versions; no fix listed\n- github.com/openbao/openbao (Go): affected all versions; fixed in 2.5.4\n- github.com/openbao/openbao (Go): affected all versions; fixed in 2.5.4\n- openbao (Bitnami): affected all versions; fixed in 2.5.4\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-2026-46405/ (Markdown: https://insights.sbomify.com/CVE-2026-46405/index.md)","id":"CVE-2026-46405","markdown":"https://insights.sbomify.com/CVE-2026-46405/index.md","name":"CVE-2026-46405","record":{"aliases":["BIT-openbao-2026-46405","GHSA-7j6w-vvw2-5f9c","GO-2026-5225"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenBao secrets manager","requires_auth":"none","summary":"Unauthenticated requests to OpenBao's Kerberos auth method create hidden tokens, potentially exhausting resources and causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"OpenBao is an open source identity-based secrets management system. Prior to version 2.5.4, in OpenBao's Kerberos auth method on the `GET` handler, or when an `Authorization: Negotiate` header is supplied, the response is includes a `logical.Auth` object in addition to an error message. This results in tokens being created with only the default policy, default TTL, and no entity information, which are hidden by the returned error message. No access to these tokens by the caller occurs and the authentication token is not ever made accessible outside of `sys/raw`. This is fixed in OpenBao v2.5.4. As a workaround, users may set a rate limit quota to limit the creation of these paths. As the path is unauthenticated, it isn't possible to deny access to it.","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 Kerberos Auth Method Accumulates Unaccessible Tokens","id":"CVE-2026-46405","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":4,"n_references":4,"next":{"headline":"Claude Code: Insecure Temporary File in /copy Command Enables Response Disclosure and Symlink-Based File Write","id":"CVE-2026-46406"},"packages":[{"ecosystem":"Bitnami","fixed":["2.5.4"],"introduced":["0"],"last_affected":[],"package":"openbao","purl":"pkg:bitnami/openbao","source":"BIT-openbao-2026-46405"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","source":"GO-2026-5225"},{"ecosystem":"Go","fixed":["2.5.4"],"introduced":["0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":null,"source":"GHSA-7j6w-vvw2-5f9c"},{"ecosystem":"Go","fixed":["2.5.4"],"introduced":["0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","source":"GHSA-7j6w-vvw2-5f9c"}],"prev":{"headline":"BigBlueButton: Presentation URL Security Hardening","id":"CVE-2026-46404"},"products":["openbao"],"published":"2026-08-07","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-13","vendors":["openbao"]},"summary":"Unauthenticated requests to OpenBao's Kerberos auth method create hidden tokens, potentially exhausting resources and causing denial of service.","url":"https://insights.sbomify.com/CVE-2026-46405/"}
