Name of the Vulnerable Software and Affected Versions: FasterXML jackson-databind versions 2.x before 2.9.10.5

Description: The issue is related to the deserialization mechanism in the Jackson-databind library, specifically with the com.sun.org.apache.xalan.internal.lib.sql.JNDIConnectionPool component. This can allow a remote attacker to execute arbitrary code. The problem arises from the interaction between serialization gadgets and typing.

Recommendations: For FasterXML jackson-databind versions 2.x before 2.9.10.5, update to version 2.9.10.5 or later to resolve the issue. As a temporary workaround, consider restricting the use of the com.sun.org.apache.xalan.internal.lib.sql.JNDIConnectionPool component until a patch is applied.
