Coder: PKCS#7 signature bypass in Azure instance identity allows unauthenticated agent token theft

Summary azureidentity.Validate verifies that the PKCS7 signer certificate chains to a trusted Azure CA but never verifies the PKCS7 signature itself. An attacker can embed a legitimate Azure certificate alongside arbitrary content e.g. "vmId":"" and the forged vmId will be accepted returning the...

gitsign --verify panics on empty-certificate PKCS7 and exits 0, bypassing exit-code callers

Summary CertVerifier.Verify in pkg/git/verifier.go unconditionally dereferences certs0 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,...

CVE-2026-0819 Stack buffer overflow in PKCS7 SignedData encoding with custom signed attributes

A stack buffer overflow vulnerability exists in wolfSSL's PKCS7 SignedData encoding functionality. In wcPKCS7BuildSignedAttributes, when adding custom signed attributes, the code passes an incorrect capacity value esd-signedAttribsCount to EncodeAttributes instead of the remaining available space...
