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.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":null}],"references":["https://github.com/openbao/openbao/security/advisories/GHSA-g46h-2rq9-gw5m","https://github.com/openbao/openbao/pull/1756","https://github.com/openbao/openbao/commit/d418f238bc99adc72c73109faf574cc2b672880c","https://github.com/openbao/openbao/blob/788536bd3e10818a7b4fb00aac6affc23388e5a9/http/logical.go#L50"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2025-34895","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 17, 2025, 4:03:23 PM","dateUpdated":"Oct 17, 2025, 5:22:52 PM"},"relatedAdvisories":[{"id":"openSUSE-SU-2025:15710-1","title":"govulncheck-vulndb-0.0.20251105T184115-1.1 on GA media","vulnerabilityIds":["CVE-2016-11063","CVE-2016-11066","CVE-2016-11067","CVE-2016-11068","CVE-2016-11069","CVE-2016-11070","CVE-2016-11071","CVE-2016-11072","CVE-2016-11073","CVE-2016-11074","CVE-2016-11075","CVE-2016-11076","CVE-2016-11077","CVE-2016-11078","CVE-2016-11079","CVE-2016-11080","CVE-2016-11081","CVE-2016-11082","CVE-2016-11083","CVE-2016-11084","CVE-2017-18872","CVE-2023-32199","CVE-2024-58269","CVE-2025-10545","CVE-2025-10678","CVE-2025-10954","CVE-2025-11374","CVE-2025-11375","CVE-2025-11579","CVE-2025-11621","CVE-2025-12044","CVE-2025-26625","CVE-2025-27093","CVE-2025-41410","CVE-2025-41443","CVE-2025-54286","CVE-2025-54287","CVE-2025-54288","CVE-2025-54289","CVE-2025-54290","CVE-2025-54291","CVE-2025-54293","CVE-2025-54469","CVE-2025-54470","CVE-2025-54471","CVE-2025-54499","CVE-2025-58073","CVE-2025-58075","CVE-2025-58356","CVE-2025-59043","CVE-2025-59048","CVE-2025-59530","CVE-2025-59836","CVE-2025-59937","CVE-2025-61141","CVE-2025-61524","CVE-2025-61581","CVE-2025-61688","CVE-2025-62156","CVE-2025-62157","CVE-2025-62375","CVE-2025-62506","CVE-2025-62513","CVE-2025-62705","CVE-2025-62714","CVE-2025-62725","CVE-2025-62820","CVE-2025-64101","CVE-2025-64102","CVE-2025-64103"]},{"id":"WID-SEC-W-2025-2391","title":"OpenBao: Mehrere Schwachstellen","vulnerabilityIds":["CVE-2025-62513","CVE-2025-62705","CVE-2025-59043"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
