The rapidjson parser uses a recursive parsing method by default. If the input json has a large depth of recursive structure, the parser function may run into stack overflow.\n\nAffected Scenarios:\nUse bRPC server with protobuf message to serve http+json requests from untrusted network. Or directly use\u00a0JsonToProtoMessage to convert json from\u00a0untrusted input.\n\n\n\nHow to Fix: \n(Choose one of the following options)\u00a0\n1. Upgrade bRPC to version 1.15.0, which fixes this issue.\n2. Apply this patch: https://github.com/apache/brpc/pull/3099 \n\n\n\nNote:\nNo matter which option \n\nyou choose, you should know that the fix introduces a recursion depth limit with default value 100. It affects these functions:\u00a0\n\nProtoMessageToJson, ProtoMessageToProtoJson, JsonToProtoMessage, and ProtoJsonToProtoMessage.\n\n If your requests contain json or protobuf messages that have a depth exceeding the limit, the request will be failed after applying the fix. You can modify the gflag json2pb_max_recursion_depth to change the limit."}], "lastModified": "2025-12-02T14:39:47.780", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:apache:brpc:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8FC82429-4B83-4132-A67A-146ABA8A0F27", "versionEndExcluding": "1.15.0"}], "operator": "OR"}]}], "sourceIdentifier": "security@apache.org"}
