CVE-2026-83780

Legacy Update is a tool for activating and installing updates on legacy Windows PCs. Legacy Update 1.12.0 through 1.13.1 contains an origin validation error in the IsPermitted method of its ActiveX control. After successfully reading the hosting document's hostname, a hostname that is not on the permitted list falls through without setting E_ACCESSDENIED, causing IsPermitted to return S_OK. An attacker who induces a user to visit a malicious webpage in Internet Explorer can invoke the control to enumerate update and system information, install updates without consent, display dialogs, or restart the computer when a reboot is pending. This issue was fixed in Legacy Update 1.13.2.

IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.10 is vulnerable by an authentication bypass vulnerability when samlWeb-2.0 feature is enabled.

IBM WebSphere Application Server - Liberty 20.0.0.12 through 26.0.0.10 could allow an unauthenticated remote attacker to bypass access controls configured on gRPC service methods.

ColdFusion RDS is affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could lead to arbitrary file system read. An attacker could exploit this vulnerability to access sensitive files and directories outside the intended access scope. Exploitation of this issue does not require user interaction. Scope is changed. RDS is purely a development feature meant for debugging purposes, and switching ColdFusion to Production Secure Profile automatically disables RDS. The Lockdown Guide outlines the specific step to disable RDS if a ColdFusion server is not being used in Production Secure Profile.

ColdFusion is affected by an Incorrect Authorization vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could exploit this vulnerability to execute arbitrary code. The vulnerable component is restricted to an administrative network zone by default. Exploitation of this issue does not require user interaction. Scope is changed.

Xorbits Xoscar through 0.11.2 contains an unauthenticated deserialization vulnerability that allows remote attackers to execute arbitrary code by sending crafted data over the actor-pool TCP channel. Attackers can exploit SocketChannel.recv() passing unvalidated data to cloudpickle.loads(), which triggers pickle __reduce__ gadget execution before message type validation, achieving remote code execution as the server process which commonly runs as root on GPU nodes.

ColdFusion is affected by a Code Injection vulnerability (improper control of code generation) that could result in arbitrary code execution in the context of the current user. Exploitation does not require user interaction and the scope is changed.

ColdFusion is affected by a Server-Side Request Forgery (SSRF) vulnerability that could result in privilege escalation. Exploitation does not require user interaction and the scope is changed.

ColdFusion is affected by a Code Injection vulnerability (improper control of code generation) that could result in arbitrary code execution in the context of the current user. Exploitation does not require user interaction.

ColdFusion is affected by an Incorrect Authorization vulnerability that could result in a security feature bypass. A low-privileged attacker could bypass security measures and gain unauthorized write access. Exploitation does not require user interaction and the scope is changed.
