Name of the Vulnerable Software and Affected Versions Polkadot Frontier versions prior to commit 36f70d1

Description Polkadot Frontier is an Ethereum and EVM compatibility layer for Polkadot and Substrate. The Curve25519Add and Curve25519ScalarMul precompiles incorrectly handle invalid Ristretto point representations. Instead of returning an error, they silently treat invalid input bytes as the Ristretto identity element, potentially leading to incorrect cryptographic results.

Recommendations Update to commit 36f70d1 or a later version to address this issue.
