GHSA-9RM7-3QHH-H2MC Wire: Unauthenticated decoder crash via 32-bit length integer overflow in ByteArrayProtoReader32 (incomplete fix of CVE-2026-45799)

Wire's protobuf decoders did not consistently validate attacker-controlled length-delimited sizes against the current reader bounds before computing cursor, limit, or pointer positions. In the Kotlin runtime, ProtoAdapter.decodeByteArray and ProtoAdapter.decodeByteString use the ProtoReader32 fas...

CVE-2026-63126

Wire (a gRPC and protocol buffers library by Square for Android, Kotlin, Swift, and Java) has an integer overflow in its 32-bit protobuf decoder. Prior to 6.4.5 and 7.0.0-alpha04 , ByteArrayProtoReader32.internalNextLengthDelimited() in Kotlin allows a positive oversized length to wrap pos + leng...

CVE-2026-45799

Wire provides gRPC and protocol buffers for Android, Kotlin, Swift, and Java. Prior to 6.3.0 and 7.0.0-alpha03, ByteArrayProtoReader32.skipGroup and ProtoReader.skipGroup in wire-runtime do not validate that a LENGTHDELIMITED field length is non-negative before skip, allowing a crafted protobuf...
