Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound via MessageUnpacker.skipValue in msgpack-core/src/main/java/org/msgpack/core/MessageUnpacker.java. An attacker can desynchronize the parser and cause attacker-controlled data to be returned in place of lat...

DEBIAN-CVE-2026-90472

msgpack-java through 0.9.12 contains a stack overflow vulnerability in MessageUnpacker.unpackValue that recursively deserializes arrays and maps without nesting depth limits. Attackers can craft payloads with deeply nested arrays to exhaust the deserializing thread's stack and trigger...

DEBIAN-CVE-2026-90473
