description
jackson-core can allocate an excessively large error message while handling malformed JSON through its DataInput-backed parser. An attacker may exhaust application memory or disrupt the JVM by supplying malformed input, if the application passes attacker-controlled data to createParser(DataInput).
mitigation
Upgrade com.fasterxml.jackson.core:jackson-core to 2.18.11, 2.21.7, or 2.22.3, as appropriate; upgrade tools.jackson.core:jackson-core to 3.1.7 or 3.2.3. Until upgraded, avoid parsing untrusted input through the DataInput parser path.
fixed in 2.21.7, 2.22.3, 3.1.7, 3.2.3, 2.18.11
