CVE-2026-110747

ProtobufParser.readStringKey reads the length prefix of a protobuf map entry's string key into an attacker-controlled int and then checks inputPtr + len = inputEnd using signed arithmetic. For values near Integer.MAXVALUE the addition overflows to a negative value and the check passes even when t...

CVE-2026-104016

ProtobufParser parses length-prefixed protobuf string and bytes fields by checking inputPtr + len = inputEnd and then, on the fast path, calling finishShortTextlen. Both use 32-bit signed integer arithmetic. When an attacker supplies a varint decoding to a length near Integer.MAXVALUE, inputPtr +...

CVE-2026-110747 jackson-dataformat-protobuf: integer overflow in ProtobufParser._readStringKey() allows OutOfMemoryError from an 8-byte payload

ProtobufParser.readStringKey reads the length prefix of a protobuf map entry's string key into an attacker-controlled int and then checks inputPtr + len = inputEnd using signed arithmetic. For values near Integer.MAXVALUE the addition overflows to a negative value and the check passes even when t...

CVE-2026-110747

The jackson-dataformat-protobuf library is vulnerable to an integer overflow in the ProtobufParser._readStringKey() method. When processing a protobuf map entry, the parser reads the length prefix of a string key into an attacker-controlled int and performs a bounds check using signed arithmetic....

CVE-2026-104016 jackson-dataformat-protobuf: signed integer overflow in string-length paths allows unbounded array allocation and OutOfMemoryError

ProtobufParser parses length-prefixed protobuf string and bytes fields by checking inputPtr + len = inputEnd and then, on the fast path, calling finishShortTextlen. Both use 32-bit signed integer arithmetic. When an attacker supplies a varint decoding to a length near Integer.MAXVALUE, inputPtr +...

CVE-2026-104016

The jackson-dataformat-protobuf library is vulnerable to a signed integer overflow within the ProtobufParser component when processing length-prefixed protobuf string and bytes fields. Specifically, when an attacker provides a varint decoding with a length near Integer.MAX_VALUE , the arithmetic ...
