The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in X.500 distinguished name stringification when escaping strings with quadratic-time behavior. A remote attacker can supply crafted distinguished names to cause a denial of service.


7) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2026-12816)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to forge message authentication codes.

The vulnerability exists due to improper cryptographic implementation in IESEngine stream-mode MAC processing when deriving keys through a length-dependent KDF split. A remote attacker can supply crafted input to forge message authentication codes.


8) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2026-12803)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to forge authenticated ciphertexts across nonces.

The vulnerability exists due to improper cryptographic binding in KCCMBlockCipher MAC processing when AAD is absent. A remote attacker can craft data that exploits the missing nonce binding to forge authenticated ciphertexts across nonces.


9) Insufficient verification of data authenticity (CVE-ID: CVE-2026-59642)
