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...

CVE-2026-89425

The FasterXML jackson-core library contains a vulnerability in the UTF8DataInputJsonParser._reportInvalidToken() method. The root cause is that this specific parser fails to honor ErrorReportConfiguration.getMaxErrorTokenLength() (default 256) when building error messages, unlike other sibling im...

CVE-2026-89425 jackson-core: UTF8DataInputJsonParser._reportInvalidToken() does not honor maxErrorTokenLength, allowing unbounded StringBuilder growth

UTF8DataInputJsonParser.reportInvalidToken in FasterXML jackson-core builds the offending-token text for its error message by appending Java identifier characters to a StringBuilder in a loop that has no upper bound. Unlike the three sibling parser implementations, including UTF8StreamJsonParser,...
