CVE-2025-65945-poc

CVE-2025-65945: node-jws 签名绕过 这是 node-jws 库中签名验证绕过漏洞的概念验证。该漏洞允许攻击者在服务器从用户可控数据派生 HMAC 密钥时伪造有效的 JWT。 漏洞原理是什么？ jws.createVerify 函数在使用 HMAC 算法时，不会验证是否确实提供了密钥。如果你的应用程序根据 JWT 中的某些内容（如 kid 头）查找密钥，并且查找失败，那么你最终可能会使用空密钥进行验证。 攻击者可以利用这一点： 1. 发送一个包含不存在于数据库中的虚假密钥 ID 的 JWT 2. 使用空字符串作为密钥签署其恶意负载 3. 服务器的查找返回...

CVE-2026-85394 python-jose through 3.5.0 Algorithm Confusion via DER-encoded Public Key as HMAC Secret

python-jose through 3.5.0 fails to properly validate asymmetric keys in HMAC initialization, accepting DER-encoded public keys that lack PEM armor or SSH prefixes. Attackers holding the service's public key can forge HS256 tokens that pass verification when algorithms are not explicitly restricte...

CVE-2026-3416

WSO2 products' API Publisher component used a non-cryptographic pseudorandom number generator (PRNG) to generate shared secrets for Webhook HMAC validation. Because the PRNG lacks sufficient entropy, a sophisticated attacker can predict future secrets and forge event payloads with valid HMAC sign...

CVE-2026-3416 Predictable Pseudorandom Number Generation via Webhook HMAC Secret Generation in Multiple WSO2 Products Allows Forged Event Payloads

The API Publisher component previously used a non-cryptographic pseudorandom number generator PRNG to create shared secrets for Webhook HMAC validation. This PRNG lacks sufficient entropy for security-sensitive operations, allowing a sophisticated attacker to predict future secrets. This enables...

CVE-2026-15656

CVE-2026-15656 affects IBM Maximo Application Suite (MAS) 9.2, 9.1, and 9.0. The issue is that authorization tokens and session cookies are not marked with the Secure attribute, allowing cookies to be exposed if a user visits an http link or a site containing such a link. As described in the conn...

CVE-2026-18531

CVE-2026-18531 affects IBM Maximo Application Suite (MAS) versions 9.0, 9.1, and 9.2. The issue is due to a weak HMAC session signing secret, which could allow a remote attacker to tamper with session data. The consequence is potential session integrity loss without requiring user interaction. Ac...

python-pyjwt: PyJWT: Authentication bypass due to forged JSON Web Tokens

A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...

Security Bulletin: IBM MAS uses axios-1.15.2, protobufjs-8.0.1 and undici-7.26 which is vulnerable to multiple CVEs, and contains vulnerabilities related to missing Secure attribute on mas-redirect-uri cookie and weak HMAC Session Secret

Summary IBM Maximo Application Suite uses axios-1.15.2.tgz, protobufjs-8.0.1.tgz, protobufjs-8.2.0.tgz and undici-7.26.0.tgz which is vulnerable to CVE-2026-11525, CVE-2026-12151, CVE-2026-6733, CVE-2026-6734, CVE-2026-9678, CVE-2026-9679, CVE-2026-9697, CVE-2026-54270, CVE-2026-45740,...

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...
