CVE-2026-46669 | BDVDB-2026-339539 Detail

openvm-orgopenvm

Description#

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.

Impact#

Per CVSS v4.0: confidentiality impact none, integrity impact high, availability impact none. Attack vector: network.
