From 0.4.0 to before 0.15.0, CertVerifier.Verify() in pkg/git/verifier.go unconditionally dereferences certs[0] after sd.GetCertificates() without checking the slice length. A CMS/PKCS7 signed message with an empty certificate set is a structurally valid DER payload; GetCertificates() returns an empty slice with no error, causing an immediate index-out-of-range panic. On the gitsign --verify code path (the GPG-compatible mode invoked by git verify-commit), the panic is silently recovered by internal/io/streams.go's Wrap() function, which returns nil instead of an error. main.go then exits with code 0, causing exit-code-only verification callers to interpret the failed verification as success. This vulnerability is fixed in 0.15.0.","state":0,"publishedAt":"2026-05-15T17:16:47.43+00:00","modifiedAt":"2026-06-17T10:50:28.823+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/sigstore/gitsign/security/advisories/GHSA-7c37-gx6w-8vc5"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-44310","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-129","CWE-390"],"productCriteria":[],"sourceDates":{"published":"2026-05-15T17:16:47.430","lastModified":"2026-06-17T10:50:28.823"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
