IBM WebSphere Extreme Scale 8.6.1.0 through 8.6.1.6 Approximately 50 generated CORBA stub classes in WebSphere eXtreme Scale's ogclient.jar call ORB.string_to_object() on an attacker-controlled IOR string during Java deserialization, turning any unfiltered ObjectInputStream sink in WAS into outbound IIOP SSRF to an attacker-chosen host; when chained with the IBM ORB's getUserException class-instantiation flaw (WAS-26), this SSRF escalates to remote code execution on the calling JVM.

——30SSRF exists in osTicket before 1.14.3, where an attacker can add malicious file to server or perform port scanning.6dCVE-2026-445788.6 ALT98.4%
——30Next.js is a React framework for building full-stack web applications. From 13.4.13 to before 15.5.16 and 16.2.5, self-hosted applications using the built-in Node.js server can be vulnerable to server-side request forgery through crafted WebSocket upgrade requests. An attacker can cause the server to proxy requests to arbitrary internal or external destinations, which may expose internal services or cloud metadata endpoints. Vercel-hosted deployments are not affected. This vulnerability is fixed in 15.5.16 and 16.2.5.15hCVE-2023-271597.5 ALT98.3%
——29Appwrite up to v1.2.1 was discovered to contain a Server-Side Request Forgery (SSRF) via the component /v1/avatars/favicon. This vulnerability allows attackers to access network resources and sensitive information via a crafted GET request.8dCVE-2026-483327.7 ALT95.7%
——29ColdFusion is affected by a Server-Side Request Forgery (SSRF) vulnerability that could result in a Security feature bypass. A low-privileged attacker could leverage this vulnerability to bypass security measures and gain unauthorized read access. Exploitation of this issue does not require user interaction.
