Fixes #5560

Summary

Replaces dangerous eval() in memory bank data unpacking with json.loads() to prevent arbitrary code execution.

Severity: 🟠 High — Malicious memory entries could execute arbitrary code during unpacking.

Changes

  • Replaced eval(raw) with json.loads(raw)
  • Added proper error handling for malformed JSON

Files Changed

  • framework/memory.py — +5/-2 lines

Test Plan

  • All 4 tests passing on fix branch

Note: Using micro-fix bypass. Please assign me to the linked issue.

Remove `**memory` from the edge condition evaluation context.
Unpacking arbitrary memory keys directly into the eval namespace
allowed adversarial content to shadow built-in names or inject
unexpected variables into the safe_eval evaluator.

Memory values are still accessible via `memory["key"]` or
`memory.get("key")` in condition expressions.
