CVE-2026-5430 Authentication Bypass via JWT Algorithm Mismatch in Multiple WSO2 Products Allows Account Takeover

The JWT authentication mechanism accepts tokens signed with algorithms other than those explicitly configured or supported. This allows an attacker to craft a JWT with an unsupported algorithm, which is then incorrectly validated, leading to unauthorized access. Successful exploitation of this...

Security Misconfiguration org.bouncycastle:bcprov-lts8on Dependency in Confluence Data Center

This is a vulnerability in a non-Atlassian Confluence dependency. Atlassian's application of this dependency presents a lower, non-critical assessed risk. This Critical severity Security Misconfiguration vulnerability was introduced in versions 8.9.0, 9.0.1, 9.1.0, 9.2.0, 9.3.1, 9.4.0, 9.5.1,...

CVE-2026-8470: Use of a Broken or Risky Cryptographic Algorithm

IBM Langflow OSS 1.0.0 through 1.10.3, 1.0.0 through 1.10.3, 1.0.0 through 1.10.3, and 1.0.0 through 1.10.3 use Python's non-cryptographic random module for generating Fernet encryption keys from user secrets under 32 characters. The deterministic Mersenne Twister PRNG produces identical keys for...

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...

github.com/go-jose/go-jose/v3: github.com/go-jose/go-jose/v4: Go JOSE: Denial of Service via crafted JSON Web Encryption (JWE) object

A flaw was found in Go JOSE, a library for handling JSON Web Encryption JWE objects. A remote attacker could exploit this vulnerability by providing a specially crafted JWE object. When decrypting such an object, if a key wrapping algorithm is specified but the encrypted key field is empty, the...

CVE-2026-38447

osTicket 1.18.3 generates API keys using a predictable construction based on MD5 hashing. The use of MD5, combined with predictable inputs such as the current timestamp and client IP address, significantly reduces entropy. An attacker can approximate the key generation time and brute-force the ke...

CVE-2025-15631 Weak Credential Storage in TP-Link Omada Devices

A cryptographic weakness exists in affected Omada devices where site credentials are protected using a legacy hashing algorithm that does not provide sufficient protection. An attacker who obtains access to stored credential data may be able to recover valid credentials to gain unauthorized acces...
