The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Start learningA fix was pushed into the master
branch but not yet published.
Affected versions of this package are vulnerable to Improper Input Validation. In pallet-ethereum
, a part of the transaction validation logic was called in the transaction pool validation, but not in block execution. Malicious actors can abuse this to put invalid transactions into a block.
The attack is limited such that the signature is always validated, and the majority of the validation is done again in the subsequent pallet-evm
execution logic. However, a chain ID replay attack is possible. Moreover, spamming attacks are of main concern, while they are limited by substrate block size limits and other factors.
