GHSA-XCQX-9JF5-W339 SearXNG MCP Server: Unbounded Response Body Read Bypasses URL Size Limit in `web_url_read`

Unbounded Response Body Read Bypasses URL Size Limit in weburlread Summary The weburlread MCP tool in mcp-searxng enforces its 5 MiB response-size limit exclusively by inspecting the Content-Length header of a preliminary HEAD request. When a server omits Content-Length — a standard HTTP practice...

CVE-2026-48979 PHP Standard Library: HTTP/2 server-side missing content-length validation enables request smuggling

PHP Standard Library PSL is set of APIs covering async, collections, networking, I/O, cryptography, terminal UI, etc. In versions 6.1.0, 6.1.1 and 6.2.0, the Psl\H2\ServerConnection does not validate that the total bytes received in DATA frames match the content-length header declared in the...

CVE-2026-54387

Tinyproxy through 1.11.3, fixed in commit ff45d3b, fails to reconcile conflicting Content-Length and Transfer-Encoding: chunked headers, forwarding both verbatim to the backend while using Content-Length to determine how many request body bytes to consume. Remote attackers can desynchronize the...
