CVE-2026-44288 protobufjs: Overlong UTF-8 decoding

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.6 and 8.0.2, protobufjs includes a minimal UTF-8 decoder that accepted overlong UTF-8 byte sequences and decoded them to their canonical characters instead of replacing them. An attacker who can provide protobuf...

CVE-2026-44288

CVE-2026-44288 affects protobufjs: prior to versions 7.5.6 and 8.0.2, its minimal UTF-8 decoder accepted overlong UTF-8 byte sequences and decoded them to canonical characters instead of replacing them. If an attacker supplies protobuf binary data decoded through that path, downstream checks that...
