CVE-2025-65945-poc

CVE-2025-65945: node-jws Signature Bypass This is a proof of concept for a signature verification bypass in the node-jws library. The bug lets attackers forge valid JWTs when the server derives HMAC secrets from user-controlled data. What's the bug? The jws.createVerify function doesn't validate...

CVE-2026-102273

A flaw was found in PyJWT. This vulnerability allows an unauthenticated remote attacker to bypass authentication by forging arbitrary JSON Web Tokens JWTs. When an application allows both symmetric and asymmetric algorithms, PyJWT fails to properly validate public JSON Web Key JWK container...

CVE-2026-102271 PyJWT: Public keys in DER form are accepted as HMAC secrets, bypassing the CVE-2022-29217 guard

PyJWT is a Python implementation of JSON Web Token standards. From 2.4.0 until 2.14.0, PyJWT HMACAlgorithm.preparekey is affected because asymmetric-key guard relies on textual markers that are absent from DER encoding. This occurs when an application mixes HMAC and asymmetric algorithms and...

CVE-2026-102271

The PyJWT Python library (versions 2.4.0 through 2.14.0 ) is vulnerable in the HMACAlgorithm.prepare_key function. The root cause is that the asymmetric-key guard relies on textual markers that are missing from DER encoding . When an application mixes HMAC and asymmetric algorithms and provides a...

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 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

IBM Maximo Application Suite 9.2, 9.1, and 9.0 could allow a remote attacker to tamper with session data due to the use of a weak HMAC session signing secret...

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...

CVE-2026-18531: Use of Insufficiently Random Values

IBM Maximo Application Suite 9.2, 9.1, and 9.0 could allow a remote attacker to tamper with session data due to the use of a weak HMAC session signing secret...

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,...
