CVE-2025-59789 (GCVE-0-2025-59789)

Vulnerability from cvelistv5 – Published: 2025-12-01 10:22 – Updated: 2025-12-01 15:05

Summary

Uncontrolled recursion in the json2pb component in Apache bRPC (version < 1.15.0) on all platforms allows remote attackers to make the server crash via sending deep recursive json data. Root Cause: The bRPC json2pb component uses rapidjson to parse json data from the network. 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. Affected Scenarios: Use bRPC server with protobuf message to serve http+json requests from untrusted network. Or directly use JsonToProtoMessage to convert json from untrusted input. How to Fix: (Choose one of the following options) 1. Upgrade bRPC to version 1.15.0, which fixes this issue. 2. Apply this patch: https://github.com/apache/brpc/pull/3099 Note: No matter which option you choose, you should know that the fix introduces a recursion depth limit with default value 100. It affects these functions: ProtoMessageToJson, ProtoMessageToProtoJson, JsonToProtoMessage, and ProtoJsonToProtoMessage. 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.

GHSA-X4FP-GJPV-C6R5

Vulnerability from github – Published: 2025-12-01 12:30 – Updated: 2025-12-01 15:30

Details

Uncontrolled recursion in the json2pb component in Apache bRPC (version < 1.15.0) on all platforms allows remote attackers to make the server crash via sending deep recursive json data.

Root Cause: The bRPC json2pb component uses rapidjson to parse json data from the network. 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.

Affected Scenarios: Use bRPC server with protobuf message to serve http+json requests from untrusted network. Or directly use JsonToProtoMessage to convert json from untrusted input.

How to Fix: (Choose one of the following options) 1. Upgrade bRPC to version 1.15.0, which fixes this issue. 2. Apply this patch: https://github.com/apache/brpc/pull/3099

Note: No matter which option

you choose, you should know that the fix introduces a recursion depth limit with default value 100. It affects these functions:

ProtoMessageToJson, ProtoMessageToProtoJson, JsonToProtoMessage, and ProtoJsonToProtoMessage.

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.

  "details": "Uncontrolled recursion in the json2pb component in Apache bRPC (version \u003c 1.15.0) on all platforms allows remote attackers to make the server crash via sending deep recursive json data.\n\nRoot Cause:\nThe bRPC\u00a0json2pb component uses rapidjson to parse json data from the network. 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.",
