com.fasterxml.jackson.core/jackson-core: tools.jackson.core/jackson-core: jackson-core: Denial of Service via incomplete fix in async JSON parser

A flaw was found in jackson-core. A remote attacker can exploit an incomplete fix in the non-blocking JSON parser by streaming specially crafted JSON data in small chunks. This bypasses the intended number length constraint, causing the parser to accumulate excessive memory per connection. This...

jackson-core: UTF8DataInputJsonParser._reportInvalidToken() missing maxErrorTokenLength limit -> unbounded StringBuilder growth (DoS)

Status FULLY REPRODUCED. A malformed token fed through createParserDataInput produced a 20,000,109-character exception message from a 20-million-character attacker payload, while the identical payload fed through createParserInputStream produced a correctly bounded 367-character message. Affected...
