Spring Framework 6.2.x < 6.2.20 / 7.0.x < 7.0.8.1 Multiple Vulnerabilities

The version of Spring Framework installed on the remote host is 6.2.x prior to 6.2.20, or 7.0.x prior to 7.0.8.1. It is, therefore, affected by multiple vulnerabilities: - UrlHandlerFilter can be vulnerable to an open redirect when configured with very broadly matching patterns. The issue applies...

CVE-2026-53965 MCP PHP SDK: Unbounded SSE buffer in HttpTransport enables client-side denial of service

The MCP PHP SDK Composer package mcp/sdk is the official Model Context Protocol SDK for PHP. In versions 0.5.0 through 0.7.0, the HTTP client transport reads a Server-Sent Events response stream incrementally and appends each chunk to an in-memory buffer with no upper bound. The buffer is only...

GHSA-7M52-JW36-44R3 MCP PHP SDK: client HttpTransport SSE buffer (sseBuffer .= chunk) grows unbounded when server withholds the event delimiter

Summary The HTTP client transport in mcp/sdk reads a Server-Sent-Events SSE response stream incrementally and appends each 4 KiB chunk to an in-memory buffer $this-sseBuffer .= $chunk; with no upper bound. The buffer is only ever flushed when an SSE event delimiter "\n\n" appears. A remote MCP...

CVE-2026-73405

CVE-2026-73405 describes an authorization bypass in Vulnerability-Lookup where the Pub/Sub SSE interface allowed unconfirmed/inactive accounts to subscribe to /pubsub/subscribe/ due to token_required only validating the API key, not is_active/is_confirmed. This created a boundary mismatch with th...
