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 &#8211;verify code path (the GPG-compatible mode invoked by git verify-commit), the panic is silently recovered by internal\/io\/streams.go&#8217;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.<\/p>\n<p>  Severity: 0.0 | NA<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-44310 Published : May 15, 2026, 4:17 p.m. | 40\u00a0minutes ago Description :Gitsign is a keyless Sigstore to signing tool for Git commits with your a GitHub \/ OIDC identity.
