NVD Description

Note: Versions mentioned in the description apply only to the upstream n8n package and not the n8n package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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.
