Prior to 7.5.6 and 8.0.2, protobufjs could recurse without a depth limit while decoding nested protobuf data. This affected both skipping unknown group fields and generated decoding of nested message fields. A crafted protobuf binary payload could cause the JavaScript call stack to be exhausted during decoding. This vulnerability is fixed in 7.5.6 and 8.0.2.\n\n## Affected\n\n- `protobufjs < 7.5.6`\n- `protobufjs >= 8.0.0, < 8.0.2`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `protobufjs 8.0.2`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
