This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 87% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

OpenVM is a performant and modular zkVM framework built for customization and extensibility. Prior to version 1.6.0, the openvm-pairing guest library's try_honest_pairing_check function invokes Theorem 3 of https://eprint.iacr.org/2024/640.pdf but does not check that the scaling factor s is in a proper subfield of Fp12. This allows incorrect results to the pairing check. This issue has been patched in version 1.6.0.
