#vulnerability

### Summary When assert statements are bypassed, an infinite loop can occur, resulting in a DoS attack when processing a POST body. ### Impact If optimisations are enabled (`-O` or `PYTHONOPTIMIZE=1`), and the application includes a handler that uses the `Request.post()` method, then an attacker may be able to execute a DoS attack with a specially crafted message. ------ Patch: https://github.com/aio-libs/aiohttp/commit/bc1319ec3cbff9438a758951a30907b072561259

### Summary Path normalization for static files prevents path traversal, but opens up the ability for an attacker to ascertain the existence of absolute path components. ### Impact If an application uses `web.static()` (not recommended for production deployments), it may be possible for an attacker to ascertain the existence of path components. ------ Patch: https://github.com/aio-libs/aiohttp/commit/f2a86fd5ac0383000d1715afddfa704413f0711e

### Summary The parser allows non-ASCII decimals to be present in the Range header. ### Impact There is no known impact, but there is the possibility that there's a method to exploit a request smuggling vulnerability. ---- Patch: https://github.com/aio-libs/aiohttp/commit/c7b7a044f88c71cefda95ec75cdcfaa4792b3b96

### Summary The Python HTTP parser may allow a request smuggling attack with the presence of non-ASCII characters. ### Impact If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. ------ Patch: https://github.com/aio-libs/aiohttp/commit/32677f2adfd907420c078dda6b79225c6f4ebce0

### Summary A zip bomb can be used to execute a DoS against the aiohttp server. ### Impact An attacker may be able to send a compressed request that when decompressed by aiohttp could exhaust the host's memory. ------ Patch: https://github.com/aio-libs/aiohttp/commit/2b920c39002cee0ec5b402581779bbaaf7c9138a

## Impact Applications meeting these two conditions are at risk of arbitrary JavaScript code execution, even if "safe mode" [expressionInterpreter](https://vega.github.io/vega/usage/interpreter/) is used. 1. Use `vega` in an application that attaches both `vega` library and a `vega.View` instance similar to the Vega [Editor](https://github.com/vega/editor) to the global `window`, or has any other satisfactory function gadgets in the global scope 2. Allow user-defined Vega `JSON` definitions (vs JSON that was is only provided through source code) ## Patches - With Vega v6, use `vega-selections@6.1.2` (requires ESM) - With Vega v5, use `vega-selections@5.6.3` (No ESM needed) ## Workarounds - Do not attach `vega` or `vega.View` instances to global variables or the window as the editor used to do [here](https://github.com/vega/editor/blob/e102355589d23cdd0dbfd607a2cc5f9c5b7a4c55/src/components/renderer/renderer.tsx#L239) . This is a development-only debugging practice that should n...

Anthropic's MCP TypeScript SDK versions up to and including 1.25.1 contain a regular expression denial of service (ReDoS) vulnerability in the UriTemplate class when processing RFC 6570 exploded array patterns. The dynamically generated regular expression used during URI matching contains nested quantifiers that can trigger catastrophic backtracking on specially crafted inputs, resulting in excessive CPU consumption. An attacker can exploit this by supplying a malicious URI that causes the Node.js process to become unresponsive, leading to a denial of service.

A Denial of Service (DoS) vulnerability in evershop 2.1.0 and prior allows unauthenticated attackers to exhaust the application server's resources via the "GET /images" API. The application fails to limit the height of the use-element shadow tree or the dimensions of pattern tiles during the processing of SVG files, resulting in unbounded resource consumption and system-wide denial of service.

A Blind Server-Side Request Forgery (SSRF) vulnerability in evershop 2.1.0 and prior allows unauthenticated attackers to force the server to initiate an HTTP request via the "GET /images" API. The vulnerability occurs due to insufficient validation of the "src" query parameter, which permits arbitrary HTTP or HTTPS URIs, resulting in unexpected requests against internal and external networks.

A memory leak security vulnerability allows unauthenticated attackers to extract passwords and tokens from MongoDB servers.
