description

tari_engine decodes engine-call arguments using validator CPU without charging equivalent execution cost. An attacker who can publish and execute a malicious WASM template may cause validators to spend excessive CPU processing transactions, potentially delaying chain operation.

mitigation

Restrict untrusted template publication and execution, and apply transaction admission or rate limits where available to reduce exposure. No fixed version is recorded; deploy an upstream release containing metering for engine-call argument decoding when one becomes available.
