Insufficient Verification of Data Authenticity

Overview @sigstore/verify is a Verification of Sigstore signatures Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity via the integratedTime process. An attacker can manipulate time-based verification decisions by supplying a crafted bundle that set...

GHSA-XGJW-PM74-86Q4 sigstore-js has Insufficient Verification of Data Authenticity

sigstore-js derives a transparency-log timestamp from tlogEntries.integratedTime and uses it to validate certificate validity windows and satisfy timestampThreshold. For bundle v0.2, a tlog entry can be inclusionProof-only no signed inclusionPromise/set, and the inclusion proof path does not...

Sigstore Timestamp Authority has OOM due to unbounded metric label cardinality

Impact An unauthenticated remote attacker can trigger unbounded memory growth on the timestamp authority server. This vulnerability exists because the global wrapMetrics middleware records the raw HTTP request path r.URL.Path and raw HTTP request method r.Method as Prometheus labels for latency a...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in the integratedTime verification process. An attacker can bypass certificate validity checks by providing a bundle with a manipulated integrated time, potentially allowing the reuse of ...
