CVE-2026-100886

Nezha 2.2.3 contains a Host header injection regression in the OAuth2 redirect endpoint. When the dashboard_host setting is empty, /api/v1/oauth2/{provider} reflects the attacker-supplied Host header into the redirect_uri. An attacker can steal the victim's authorization code and take over the account.

obot versions before v0.21.1 fail to enforce Access Control Rules on the /mcp-connect endpoint, allowing any authenticated user to connect to restricted MCP servers if they possess the server ID. Attackers can bypass authorization to access sensitive backend systems.

Obot up to commit d7e6970, when started via the Docker quickstart from README, listens on 0.0.0.0:8080 with authentication disabled. Every request is mapped to a synthetic 'nobody' user with Owner and Admin roles, granting full administrative access. The quickstart also mounts /var/run/docker.sock, giving access to the host's Docker control surface.

HTTP Request/Response Smuggling vulnerability in Citrix NetScaler ADC and Gateway due to inconsistent interpretation of HTTP requests.

Eval injection vulnerability in hMailServer (versions 6.0.0-6.3.3) allows a remote, unauthenticated attacker to execute arbitrary JScript in the service process with service account privileges. It requires non-default configuration: event scripting enabled, JScript as script language, and an OnClientValidatePassword handler defined. Exploitation uses a password with backslash and apostrophe that is not properly escaped.

A vulnerability in vm2 before 3.12.2 allows an authorization bypass in the NodeVM external-module resolver. When an embedder configures `require.external` with a custom resolver and `context: 'host'`, guest code can require an allowlisted module and then an absolute path of a non-allowlisted sibling sharing the resolved prefix. This leads to a sandbox escape and arbitrary code execution in the host process.

A vulnerability in D-Link DIR-895L A1_102b07 affects the tunnel_set_params function in tunnel.c of the L2TP Control Channel Parser component. Manipulation results in an out-of-bounds write. The attack can be initiated remotely, and the exploit is now public.

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Arbitrary File Upload due to insufficient file type validation in the 'uacf7_wpcf7_mail_components' function in all versions up to, and including, 3.5.50. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Note: This is only exploitable when the plugin's PDF Generator module is enabled, which is disabled by default.
