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-2025-59043 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 2.4.1\n- github.com/openbao/openbao (Go): affected all versions; fixed in 2.4.1\n- openbao (Bitnami): affected all versions; fixed in 2.4.1\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-2025-59043/ (Markdown: https://insights.sbomify.com/CVE-2025-59043/index.md)","id":"CVE-2025-59043","markdown":"https://insights.sbomify.com/CVE-2025-59043/index.md","name":"CVE-2025-59043","record":{"aliases":["BIT-openbao-2025-59043","GHSA-g46h-2rq9-gw5m","GO-2025-4039"],"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 attackers can cause out-of-memory crashes in OpenBao by sending crafted JSON payloads that bypass size limits.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"openbao","vendor":"openbao"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"OpenBao is an open source identity-based secrets management system. In OpenBao versions prior to 2.4.1, JSON objects after decoding may use significantly more memory than their serialized version. It is possible to craft a JSON payload to maximize the factor between serialized memory usage and deserialized memory usage, similar to a zip bomb, with factors reaching approximately 35. This can be used to circumvent the max_request_size configuration parameter which is intended to protect against denial of service attacks. The request body is parsed into a map very early in the request handling chain before authentication, which means an unauthenticated attacker can send a specifically crafted JSON object and cause an out-of-memory crash. Additionally, for requests with large numbers of strings, the audit subsystem can consume large quantities of CPU. The vulnerability is fixed in version 2.4.1.","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 vulnerable to denial of service via malicious JSON request processing","id":"CVE-2025-59043","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":4,"n_references":4,"next":{"headline":"Himmelblau vulnerable to GID collision via group name-derived mapping (privilege escalation)","id":"CVE-2025-59044"},"packages":[{"ecosystem":"Bitnami","fixed":["2.4.1"],"introduced":["0"],"last_affected":[],"package":"openbao","purl":"pkg:bitnami/openbao","source":"BIT-openbao-2025-59043"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","source":"GO-2025-4039"},{"ecosystem":"Go","fixed":["2.4.1"],"introduced":["0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":null,"source":"GHSA-g46h-2rq9-gw5m"},{"ecosystem":"Go","fixed":["2.4.1"],"introduced":["0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","source":"GHSA-g46h-2rq9-gw5m"}],"prev":{"headline":"PyInstaller has local privilege escalation vulnerability","id":"CVE-2025-59042"},"products":["openbao"],"published":"2025-10-17","related":[{"cvss_score":9.6,"headline":"OpenBao lacks user confirmation for OIDC direct callback mode","id":"CVE-2026-33757","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":9.4,"headline":"OpenBao has Reflected XSS in its OIDC authentication error message","id":"CVE-2026-33758","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":9.1,"headline":"OpenBao: Privileged Operator May Execute Code on the Underlying Host","id":"CVE-2025-54997","kev_date_added":null,"published":"2025-08-09"},{"cvss_score":7.5,"headline":"OpenBao Privileged Operator Identity Group Root Escalation","id":"CVE-2025-64761","kev_date_added":null,"published":"2025-11-25"},{"cvss_score":7.2,"headline":"OpenBao Root Namespace Operator May Elevate Token Privileges","id":"CVE-2025-54996","kev_date_added":null,"published":"2025-08-09"},{"cvss_score":6.9,"headline":"OpenBao Vulnerable to Unauthenticated Rekey Operation Cancellation","id":"CVE-2025-52894","kev_date_added":null,"published":"2025-06-25"}],"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":"US public information, NVD API terms","name":"NVD"},{"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":"2025-10-17","vendors":["openbao"]},"summary":"Unauthenticated attackers can cause out-of-memory crashes in OpenBao by sending crafted JSON payloads that bypass size limits.","url":"https://insights.sbomify.com/CVE-2025-59043/"}
