CVE-2026-49869

Kestra is an open-source, event-driven orchestration platform. Prior to 1.0.45 and 1.3.21, AuthenticationFilter in Kestra OSS uses request.getPath().endsWith("/configs") to whitelist the public configuration endpoint from Basic Auth. Because the check is a suffix match rather than an exact path match, any API path whose last segment is configs bypasses authentication entirely. An unauthenticated remote attacker can exploit this to create and execute arbitrary workflows without credentials. Because Kestra ships with script execution plugins (plugin-script-shell, plugin-script-python, etc.) enabled by default, this directly results in unauthenticated Remote Code Execution as root inside the Kestra worker container. This vulnerability is fixed in 1.0.45 and 1.3.21.

CVE-2026-46389

UDS Identity Config builds the Keycloak configuration image (realm, plugins, theme, truststore, JARs) consumed by UDS Core's Identity deployment. In versions 0.11.0 through 0.26.0, a logic error in the `client-kubernetes-secret` Keycloak client authenticator (shipped by `uds-identity-config` and consumed by UDS Core) causes the submitted `client_secret` to be overwritten with the mounted Kubernetes secret before comparison. An attacker who can reach the Keycloak token endpoint and knows a `client_id` using this authenticator can authenticate as that client with any `client_secret` value and obtain OAuth2 tokens scoped to the client's service account. In the case of the `uds-operator` client this token can be used to registry/modify other clients. Version 0.26.1 patches the issue.

CVE-2026-46840

Vulnerability in Oracle REST Data Services (component: Backend-as-a-Service). Supported versions that are affected are 24.2.0-26.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Oracle REST Data Services. While the vulnerability is in Oracle REST Data Services, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle REST Data Services. CVSS 3.1 Base Score 10.0 (Confidentiality, Integrity and Availability impacts).

CVE-2026-20182

May 2026: This security advisory provides the details and fix information for a vulnerability that was discovered and fixed after the was disclosed in February 2026. This new advisory is for a new vulnerability in the control connection handshaking. The section of this advisory includes Show Control Connections guidance to help with system checks.  A vulnerability in the peering authentication in Cisco Catalyst SD-WAN Controller, formerly SD-WAN vSmart, Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, and Cisco Catalyst SD-WAN Validator, formerly SD-WAN vBond, could allow an unauthenticated, remote attacker to bypass authentication and obtain administrative privileges on an affected system. This vulnerability exists because the peering authentication mechanism in an affected system is not working properly. An attacker could exploit this vulnerability by sending crafted requests to the affected system. A successful exploit could allow the attacker to log in to an affected Cisco Catalyst SD-WAN Controller as an internal, high-privileged, non-root user account. Using this account, the attacker could access NETCONF, which would then allow the attacker to manipulate network configuration for the SD-WAN fabric.

CVE-2026-42869

SOCFortress CoPilot focuses on providing a single pane of glass for all your security operations needs. Prior to 0.1.57, SOCFortress CoPilot ships a hardcoded JWT signing secret as a fallback value in backend/app/auth/utils.py:28 and ships it verbatim in .env.example. Any deployment where JWT_SECRET is not explicitly set — including the default Docker Compose setup — signs all authentication tokens with this publicly known value. An unauthenticated attacker can forge arbitrary admin-scoped JWTs and gain full control of the application and every security tool it manages without any credentials. This vulnerability is fixed in 0.1.57.

CVE-2026-41070

openvpn-auth-oauth2 is a plugin/management interface client for OpenVPN server to handle an OIDC based single sign-on (SSO) auth flows. From version 1.26.3 to before version 1.27.3, when openvpn-auth-oauth2 is deployed in the experimental plugin mode (shared library loaded by OpenVPN via the plugin directive), clients that do not support WebAuth/SSO (e.g., the openvpn CLI on Linux) are incorrectly admitted to the VPN despite being denied by the authentication logic. The default management-interface mode is not affected because it does not use the OpenVPN plugin return-code mechanism. This issue has been patched in version 1.27.3.

CVE-2026-41679

Paperclip is a Node.js server and React UI that orchestrates a team of AI agents to run a business. Prior to version 2026.416.0, an unauthenticated attacker can achieve full remote code execution on any network-accessible Paperclip instance running in `authenticated` mode with default configuration. No user interaction, no credentials, just the target's address. The chain consists of six API calls. The attack is fully automated, requires no user interaction, and works against the default deployment configuration. Version 2026.416.0 patches the issue.
