Info

Severity: LOW
Attack vector: offline

Impact

Allows an attacker with database write access to reset rate-limit counters and restore spending capacity.

Description

evm_transaction_log and evm_token_transfer_log are not integrity-protected even though rate and volume checks rely on them to count prior activity. Deleting rows silently reduces the observed historical usage.

Example flow

  1. Open the SQLite database offline.
  2. Delete rows from evm_transaction_log or evm_token_transfer_log.
  3. Submit new signing requests.
  4. Pass rate-limit checks because prior usage has been erased.

Mitigation

Protect log records with integrity metadata or move the counters into a tamper-evident store.
