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."}], "lastModified": "2025-10-24T17:13:10.880", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:openbao:openbao:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "542C558D-BFC0-4CC6-B683-74E4DFB31A30", "versionEndExcluding": "2.4.1"}], "operator": "OR"}]}], "sourceIdentifier": "[email protected]"}
