Publishedsigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 3.1.1, @sigstore/verify derives a transparency-log timestamp from tlogEntries[].integratedTime for bundle v0.2 inclusionProof-only entries even though the inclusion proof path does not cryptographically bind integratedTime, allowing an attacker who can supply an untrusted bundle to influence certificate validity and timestampThreshold verification decisions. This issue is fixed in version 3.1.1.
