AI-assisted PatchSiren debrief based on the supplied source corpus. The CVE record was published on 2026-07-17T20:17:21.963Z and has not been modified since then. The sigstore-go library, used for Sigstore signing and verification, had a vulnerability prior to version 1.2.0. A verifier configured with WithTransparencyLog(N>1) or WithSignedCertificateTimestamps(N>1) could have its multi-log threshold requi [truncated]
The CVE record was published on 2026-07-17T19:17:16.227Z and has not been modified since then. The NVD entry is currently 5.9 MEDIUM. Sigstore Timestamp Authority is a service for issuing RFC 3161 timestamps. Prior to 2.1.0, the global wrapMetrics middleware records raw HTTP request path and raw HTTP request method as Prometheus labels for latency and request count metric vectors before routing. This allo [truncated]
The sigstore-js library, used for interacting with Sigstore services, had a critical vulnerability prior to version 0.7.1. The getRegistryCredentials() function could select and transmit credentials for one registry to a different registry due to a substring match rather than an exact host match. This issue was fixed in version 0.7.1. The vulnerability has a CVSS score of 9.6 and is considered CRITICAL. D [truncated]
A vulnerability in Gitsign versions 0.4.0 through 0.14.x allows an attacker to craft a CMS/PKCS7 signed message with an empty certificate set that causes a panic during verification. Due to improper error handling in the verification code path, this panic is silently recovered and the process exits with code 0, causing automated verification systems to incorrectly interpret the failed verification as succ [truncated]
## Summary Gitsign versions prior to 0.16.0 contain a signature verification bypass vulnerability. The `gitsign verify` and `gitsign verify-tag` commands re-encode Git commit and tag objects through go-git's `EncodeWithoutSignature` before signature verification, rather than verifying against raw object bytes. This creates a semantic mismatch: malformed objects with duplicate tree headers are parsed diffe [truncated]
CVE-2026-39395 is a vulnerability in Cosign, a code signing and transparency tool for containers and binaries. The vulnerability allows cosign verify-blob-attestation to erroneously report a 'Verified OK' result for attestations with malformed payloads or mismatched predicate types. This issue was fixed in Cosign versions 3.0.6 and 2.6.3. The vulnerability affects users of Cosign, especially those relying [truncated]
