ETK-2026-1959Zero's internal tracking ID, independent of the CVE number.
waiting for further signalsZero needs more public information before it can validate it.description
openvc-core versions before 1.33.2 can incorrectly verify revoked, expired, or not-yet-valid Data Integrity credentials. A credential holder may cause policy checks to miss status, validity, or expected-type information when a verifier uses the affected credential verification paths and default policy.
mitigation
Upgrade openvc-core to version 1.33.2. Until upgraded, reject credentials with nested arrays in credential status data to reduce exposure to one known variant, but do not treat this as a complete workaround.
fixed in 1.33.2
outcome
Contextual: an exploit technique exists, but no deterministic check could cover this one.
