CVE-2026-56451

A vulnerability has been identified in Opcenter X All versions V2604. Affected applications do not properly validate the algorithm specified in the JSON Web Token JWT header. This could allow an unauthenticated remote attacker to forge arbitrary JWT, bypass authentication mechanisms and impersona...

CVE-2026-50722

A flaw was found in Libreswan's implementation of IKEv2 authentication when processing signatures utilizing the RSASSA-PKCS1-v15 scheme. The RSAauthenticatehashsignaturepkcs115rsa function does not correctly validate the DER encoding of the ASN.1 digest. A remote, unauthenticated attacker could...

Name of the Vulnerable Software and Affected Versions Windows SMB Server affected versions not specified Description An incorrect implementation of the authentication algorithm in the Windows SMB Server allows an authorized attacker to elevate privileges over a network. Recommendations At the...

PYSEC-2026-2973 py7zr: O(n^2) algorithmic complexity DoS in PackInfo._read()

Summary PackInfo.read uses an On^2 cumulative sum pattern where numstreams is read directly from the archive header. A crafted .7z archive with a large numstreams value causes excessive CPU consumption during SevenZipFile.init — no extraction is needed. A 50 KB archive takes 7 seconds of CPU time...

PYSEC-2026-3401 vantage6 node has an Improper Access Control issue

Impact Malicious algorithms can potentially access other algorithms input and output files. Patches Todo Workarounds Verify and restrict the algorithm containers that are allowed to run on your node. See here on how to do this. References https://docs.vantage6.ai/usage/running-the-node/security F...

PYSEC-2026-2592 lightrag-hku: JWT Algorithm Confusion Vulnerability

Summary The LightRAG API is vulnerable to a JWT algorithm confusion attack where an attacker can forge tokens by specifying 'alg': 'none' in the JWT header. Since the jwt.decode call does not explicitly deny the 'none' algorithm, a crafted token without a signature will be accepted as valid,...

CVE-2026-54780 CoreWCF: WS-Security Reference DigestMethod Algorithm-Suite Bypass

CoreWCF is a port of the service side of Windows Communication Foundation WCF to .NET Core. Prior to 1.8.1 and 1.9.1, the CoreWCF WS-Security 1.0 receive pipeline validates ds:SignedInfo SignatureMethod against the configured SecurityAlgorithmSuite but does not validate each ds:Reference...

GHSA-9H47-PQCX-HJR4 Better Auth has insecure cryptographic defaults in oidcProvider: alg=none advertised and plain PKCE accepted by default

Am I affected? Users are affected if all of the following are true: - Their application uses better-auth at a version below the patched release. - Their application enables oidcProvider from better-auth/plugins/oidc-provider or mcp from better-auth/plugins/mcp the mcp plugin delegates to...

PYSEC-2026-1921 SignXML's signature verification with HMAC is vulnerable to an algorithm confusion attack

When verifying signatures with X509 certificate validation turned off and HMAC shared secret set signxml.XMLVerifier.verifyrequirex509=False, hmackey=..., prior versions of SignXML are vulnerable to a potential algorithm confusion attack. Unless the user explicitly limits the expected signature...

CVE-2026-54291 Silent channel-binding authentication downgrade via unsupported certificate algorithms

pgjdbc is an open source postgresql JDBC Driver. In releases 42.7.4 through 42.7.11, channelBinding=require connections can be silently downgraded from SCRAM-SHA-256-PLUS with channel binding to plain SCRAM-SHA-256 without it, losing the man-in-the-middle protection the setting is meant to...

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...
