{"id":"CVE-2026-46669","summary":"`openvm-pairing` pairing check missing proper subfield check on scaling factor","details":"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.","aliases":["GHSA-76mq-v757-53gr"],"modified":"2026-07-08T08:13:37.966320571Z","published":"2026-06-10T20:09:31.670Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46669.json","cwe_ids":["CWE-20"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/openvm-org/openvm/releases/tag/v1.6.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46669.json"},{"type":"ADVISORY","url":"https://github.com/openvm-org/openvm/security/advisories/GHSA-76mq-v757-53gr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46669"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openvm-org/openvm","events":[{"introduced":"0"},{"fixed":"eda5bf031a6bd0960adb1dcf59b9a0a951eacb20"}],"database_specific":{"cpe":"cpe:2.3:a:openvm:openvm:*:*:*:*:*:*:*:*","source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"1.6.0"}]}}],"versions":["v1.5.0","v1.5.0-rc.1","v1.5.0-rc.0","v1.4.3","v1.4.3-rc.0","v1.4.2","v1.4.2-rc.1","v1.4.2-rc.0","v1.4.1","v1.4.1-rc.5","v1.4.1-rc.4","v1.4.1-rc.3","v1.4.1-rc.2","v1.4.1-rc.1","v1.4.1-rc.0","v1.4.0","v1.4.0-rc.6","v1.4.0-rc.10","v1.4.0-rc.9","v1.4.0-rc.8","v1.4.0-rc.7","v1.4.0-rc.5","v1.3.0","v1.3.0-rc.1","v1.2.1-rc.1","v1.2.1-rc.0","v1.2.0","v1.1.2","v1.1.1","v1.1.1-rc.1","v1.1.0","v1.0.0","v1.0.0-rc.2","v1.0.0-rc.1","v1.0.0-rc.0","v0.1.1-alpha","v0.1.0-alpha"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46669.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
