This means under honest protocol conditions, parties could experience failing tag verifications.\n\n## Resolution\n\nUpgrade to `v0.17.16` or `v0.18.1`.","state":0,"publishedAt":"2026-10-30T12:00:00+00:00","modifiedAt":"2026-10-30T11:15:02.1704531+00:00","affected":[{"ecosystem":"crates.io","name":"orion","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0.0.0-0"},{"kind":"fixed","version":"0.17.16"},{"kind":"introduced","version":"0.18.0-0"},{"kind":"fixed","version":"0.18.1"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://crates.io/crates/orion","https://rustsec.org/advisories/RUSTSEC-2026-0428.html","https://github.com/orion-rs/orion/pull/690"],"sourceUrl":"https://osv.dev/vulnerability/RUSTSEC-2026-0428","license":"OSV · upstream source license applies","key":"osv:RUSTSEC-2026-0428","identifiers":["RUSTSEC-2026-0428","GHSA-xcc6-f2jq-43x6"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
