Unsafe deserialization and object reconstruction

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

• Inventory serialization formats accepted from requests, queues, caches, files, cookies, and cross-service messages.
• Trace whether untrusted input can select classes, types, callbacks, constructors, or object hooks during decoding.
• Identify signing, schema validation, trust-boundary, and compatibility settings for each decoder.

Remediate safely

• Replace native object deserialization with a data-only format and explicit schema validation.
• If replacement is not immediate, use a safe decoder with a minimal type allowlist and disable polymorphic or executable hooks.
• Update the affected library and add inert tests for unknown types, extra fields, malformed nesting, and unsigned data.
