CVE-2024-45039 is a medium-severity flaw (CVSS 6.2) affecting gnark-crypto. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

gnark is a fast zk-SNARK library that offers a high-level API to design circuits. Versions prior to 0.11.0 have a soundness issue - in case of multiple commitments used inside the circuit the prover is able to choose all but the last commitment. As gnark uses the commitments for optimized non-native multiplication, lookup checks etc. as random challenges, then it could impact the soundness of the whole circuit. However, using multiple commitments
