CVE-2026-59877 protobufjs: Denial of Service via infinite loop in .proto option parsing

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.6.5 and 8.6.6, protobufjs parsed option names by advancing through schema tokens until reaching an = token without checking for end of input, so a crafted .proto schema that opens an option declaration and ends...

CVE-2026-59877

Summary: The CVE affects protobufjs, where the .proto parser could enter an infinite loop. Affected component: protobufjs (parsing of protobuf definitions to JS functions). Root cause: while parsing option declarations, the parser advances through tokens until an '=' is found without checking for...
