Title source: legacyExploitation Summary
EIP tracks 1 public exploit for EIP-2026-103500. PoCs published by Google Security Research.
AI-analyzed exploit summary This exploit leverages a bug in V8's RegExp constructor initialization where 'expected_nof_properties' is not set, leading to an out-of-bounds (OOB) write via incorrect calculation of 'unused_property_fields' in JSFunction::GetDerivedMap.
