      "value": "OpenVM is a performant and modular zkVM framework built for customization and extensibility. Before 1.7.0 in the 1.x line and in affected 2.0 and 2.1 prereleases, `OpenVmHalo2Verifier.verify` accepts `appExeCommit` and `appVmCommit` as `bytes32` values without checking that either is less than the `BN254` scalar field modulus. Although public-value and proof-data lengths are checked, callers can provide non-canonical 256-bit encodings greater than or equal to that modulus at the Solidity wrapper boundary. Applications relying on the wrapper can therefore accept non-canonical app executable and app VM commitments, creating ambiguity between the supplied byte-level values and the field elements used by the verifier. This issue is fixed in versions 1.7.0, 2.0.0-rc.3 and 2.1.0-preview."
