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,...

CVE-2026-29062

CVE-2026-29062 affects jackson-core: from 3.0.0 up to before 3.1.0, the UTF8DataInputJsonParser (used when parsing from java.io.DataInput) bypasses the StreamReadConstraints maxNestingDepth (default 500), allowing excessively nested JSON to cause a StackOverflowError and a resulting DoS. A simila...
