vLLM is an inference and serving engine for large language models (LLMs). The SSRF protection fix for CVE-2026-24779 add in 0.15.1 can be bypassed in the load_from_url_async method due to inconsistent URL parsing behavior between the validation layer and the actual HTTP client. The SSRF fix uses urllib3.util.parse_url() to validate and extract the hostname from user-provided URLs. However, load_from_url_async uses aiohttp for making the actual HTTP requests, and aiohttp internally uses the yarl library for URL parsing. This vulnerability in 0.17.0.

GHSA-v359-jj2v-j536 — vLLM has SSRF Protection Bypass

2026-10-02T18:41:13.566959+00:00

Affected: PyPI: vllm

## Summary

The SSRF protection fix for https://github.com/vllm-project/vllm/security/advisories/GHSA-qh4c-xf7m-gxfc can be bypassed in the `load_from_url_async` method due to inconsistent URL parsing behavior between the validation layer and the actual HTTP client.

## Affected Component

- **File**: `vllm/connections.py` - **Function**: `load_from_url_async`

## Vulnerability Details

### Root Cause

The SSRF [fix](https://github.com/vllm-project/vllm/pull/32746) uses `urllib3.util.parse_url()` to validate and extract the hostname from user-provided URLs. However, `load_from_url_async` uses `aiohttp` for making the actual HTTP requests, and `aiohttp` internally uses the `yarl` library for URL parsing.

These two URL parsers handle backslash characters (`\`) differently:

| Parser | Input URL | Parsed Host | Parsed Path | Behavior | |--------|-----------|-------------|-------------|----------| | `urllib3.parse_url()` | `https://httpbin.org\@evil.com/` | `httpbin.org` | `/%5C@evil.com/` | URL-encodes `\` as `%5C`, treats `\@evil.com/` as part of the path | | `yarl` (via aiohttp) | `https://httpbin.org\@evil.com/` | `evil.com` | `/` | Treats `\` as part of userinfo (`user: httpbin.org\`), the `@` acts as the userinfo/host separator |

### Attack Scenario

```python # Attacker provides this URL malicious_url = "https://httpbin.org\\@evil.com/"

# 1. Validation layer (urllib3.parse_url) parsed = urllib3.util.parse_url(malicious_url) # parsed.host == "httpbin.org" ✅ Passes vali…
