USN-8452-1: pbkdf2 vulnerability

Nikita Skovoroda discovered that pbkdf2 did not properly validate certain algorithm names. An attacker could possibly use this issue to generate predictable cryptographic keys, resulting in signature spoofing...

Internet Systems Consortium BIND DNSSEC DNSKEY Extended Flags denial of service vulnerability

Summary A denial of service vulnerability exists in the DNSSEC DNSKEY Extended Flags functionality of BIND versions: 9.21.21. A specially crafted mirror domain can lead to a denial of service. An attacker can serve a malicious zone to trigger this vulnerability. Confirmed Vulnerable Versions The...

CVE-2026-54533 vantage6 node has an Improper Access Control issue

vantage6 is an open-source infrastructure for privacy preserving analysis. Prior to version 5.0.0, malicious algorithms can potentially access other algorithms input and output files. Version 5.0.0 fixes the issue. As a workaround, verify and restrict the algorithm containers that are allowed to...

CVE-2026-50268

In Steeltoe, the OAEP misconfiguration affects the package Steeltoe.Configuration.Encryption 4.0.0–4.1.0, where setting encrypt:rsa:algorithm=OAEP does not enable OAEP due to an incorrect BouncyCastle transformation string. As a result, OAEP is effectively PKCS#1 v1.5 padding, the same as DEFAULT...

EUVD-2026-37016

Crypt::DSA versions before 1.21 for Perl reused the nonce across signatures, leading to private-key recovery. Crypt::DSA::sign caches the per-signature nonce material in the Key object without ever clearing it. The first sign on a Key object picks a nonce, and every later sign on that same object...

Security Bulletin: MongoDB Enterprised Advanced affected by: Use of a Broken or Risky Cryptographic Algorithm (CVE-2026-5588)

Summary There are vulnerabilities in bcpkix-jdk18on-1.83.jar used in MongoDB Enterprised Advanced for IBM, involving CVE-2026-5588. The vulnerability has been addressed.

CVE-2026-12205

Crypt::DSA for Perl versions before 1.21 reuse the per-signature nonce across signatures because the sign() function caches nonce data in the Key object and does not clear it. The first sign() selects a nonce and later signs reuse that nonce, producing identical r values, enabling potential priva...

PyJWT: Public-key JWK accepted as HMAC secret enables forged HS256 tokens when mixed families are allowed

!NOTE Exploitation requires a verifier configured with both symmetric and asymmetric algorithms in algorithms=… and a raw-JSON JWK as the key= argument, both contrary to documented usage, hence the High attack-complexity rating. Summary When the verifier is decoding JSON Web Tokens, while...
