CVE-2026-11564

A flaw was found in curl. When libcurl reuses a connection from its connection pool, an easy handle that initially used default native Certificate Authority CA trust may continue to trust the native platform store. This occurs even after the application has switched that same handle to custom CA...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

crypto/x509: Incorrect enforcement of email constraints in crypto/x509

A certificate validation flaw has been discovered in the golang crypto/x509 module. When verifying a certificate chain which contains a certificate containing multiple email address constraints which share common local portions but different domain portions, these constraints will not be properly...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...

Name of the Vulnerable Software and Affected Versions Lorex 2K Indoor Wi-Fi Security Camera affected versions not specified Description An issue exists in the device management functionality where the server fails to properly validate certificates. This flaw allows network-adjacent attackers to...

CVE-2026-46354 Coder: PKCS#7 signature bypass in Azure instance identity allows unauthenticated agent token theft

Coder allows organizations to provision remote development environments via Terraform. In versions prior tp 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, and 2.33.3, azureidentity.Validate verifies that the PKCS7 signer certificate chains to a trusted Azure CA but never verifies the PKCS7 signature...

CVE-2026-46354

Summary: A PKCS#7 signature bypass in Coder (Coder v2 before patches) allows unauthenticated token theft via Azure instance identity. The issue stems from azureidentity.Validate() validating only the signer certificate chain, not the signature itself, enabling forged PKCS#7 envelopes containing a...

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...

PYSEC-2026-1867 Issue with Amazon Redshift Python Connector and the BrowserAzureOAuth2CredentialsProvider plugin

Summary Amazon Redshift Python Connector is a pure Python connector to Redshift i.e., driver that implements the Python Database API Specification 2.0. When the Amazon Redshift Python Connector is configured with the BrowserAzureOAuth2CredentialsProvider plugin, the driver skips the SSL certifica...

PYSEC-2026-1922 SignXML's signature verification with HMAC is vulnerable to a timing 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 timing attack. The verifier may leak information about the correct HMAC when comparing...
