CVE-2026-59877 · protobufjs: Denial of Service via infinite loop in .proto option parsing
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
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 prematurely can cause parse, Root.load, or Root.loadSync to loop indefinitely. This issue is fixed in versions 7.6.5 and 8.6.6.
