▶ Listen to this briefingCVE-2026-40138
A critical pre-authentication vulnerability exists in the authentication subsystem of BeyondTrust Remote Support and Privileged Remote Access. Improper validation of authentication data may allow a network-positioned attacker to bypass access controls and gain unauthorized access to the appliance, including accounts with elevated privileges. Exploitation requires a specific authentication configuration to be enabled
CVE-2026-46590
Deserialization of Untrusted Data vulnerability in Apache Camel PQC component. The camel-pqc component persists post-quantum key metadata (KeyMetadata) through pluggable KeyLifecycleManager implementations. HashicorpVaultKeyLifecycleManager and AwsSecretsManagerKeyLifecycleManager read that metadata back from the configured secret backend by deserializing a Base64-wrapped value with a raw java.io.ObjectInputStream.readObject() and no ObjectInputFilter or class allow-list; the cast to KeyMetadata happens only after readObject() returns, so any readObject() side effects in a crafted object run before the type check. The same unfiltered legacy-migration read also remained in FileBasedKeyLifecycleManager (for the stored KeyPair and KeyMetadata). A principal who can write to the operator-controlled backend that holds these values - the HashiCorp Vault KV path, or the AWS Secrets Manager secret (requiring a Vault token or secretsmanager:PutSecretValue) - could store a crafted serialized object that is deserialized during normal key-lifecycle operations, potentially leading to code execution in the context of the application that manages the keys. This is an incomplete-remediation follow-on to CVE-2026-40048 (CAMEL-23200), which changed FileBasedKeyLifecycleManager to store metadata as JSON / PKCS#8 / X.509 but did not add an ObjectInputFilter, did not cover the Vault and AWS sibling managers, and left FileBasedKeyLifecycleManager's own legacy-migration deserialization unfiltered. This issue affects Apache Camel: from 4.18.0 before 4.18.3, from 4.19.0 before 4.21.0. Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.18.x LTS releases stream, then they are suggested to upgrade to 4.18.3. For deployments that cannot upgrade immediately, restrict write access to the key backend so that only the application's own identity can write the camel-pqc secrets (least-privilege HashiCorp Vault policies and secretsmanager:PutSecretValue …
CVE-2026-48316
ColdFusion versions 2025.9, 2023.20 and earlier are affected by an Improper Input Validation vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue does not require user interaction. Scope is changed.
CVE-2026-48614
An improper authorization vulnerability in the Plesk XML API allows an authenticated user to inject arbitrary configuration directives, resulting in arbitrary file write as root and full privilege escalation on the underlying server.
CVE-2026-5268
An authentication bypass vulnerability exists in the default SFTP server component utilized across the Ciena products listed. This vulnerability allows a remote, unauthenticated attacker to bypass security controls and gain unauthorized access to the underlying filesystem. Successful exploitation could allow an attacker to read or modify system files.
