A critical vulnerability in the widely-used Bouncy Castle Java cryptography library allows attackers to forge digital signatures by passing an empty sequence, fundamentally undermining the integrity of PKI-based security. The flaw, tracked as CVE-2026-5588, resides in the `CompositeVerifier` class within the `bcpkix` m...
A cryptographic vulnerability has been identified in the Bouncy Castle Java library's bcpkix module, enabling the PKIX draft CompositeVerifier to accept empty signature sequences as valid. The flaw, tracked as CVE-2026-5588, affects all versions from 1.49 to 1.84 and carries a CVSS severity score of 6.3 (moderate). Th...
A critical cryptographic vulnerability in the Bouncy Castle BC-JAVA library allows empty signature sequences to pass verification checks under certain PKIX configurations. The flaw, tracked as CVE-2026-5588 and classified under CWE-327 (Use of Broken or Risky Cryptographic Algorithm), affects the bcpkix module across m...
