CVE-2026-71887: Improper Verification of Cryptographic Signature

In Bouncy Castle for Java before 1.86, the high-level OpenPGP API accepted a data signature made by a signing subkey whose Subkey Binding signature carried no embedded Primary Key Binding cross-certification signature, in the case where that binding omits a Key Flags subpacket. RFC 9580 sec...

CVE-2026-71891: Improper Verification of Cryptographic Signature
