What it detects
Insecure deserialization: Java ObjectInputStream: an injection check run by the textscan analyzer.
Evidence
The matching source path, line, and bounded code observation produced by the native rule.
Remediation
Avoid Java native serialization on untrusted input. Prefer a data format (JSON) with a safe parser, or install an ObjectInputFilter allowlist (JEP 290).
Limitations
This check is limited to the applicability and evidence delivered by textscan. Review the evidence in context; a match is a finding input, while confidence and policy determine its disposition.
