Summary
Chainlit contain a server-side request forgery (SSRF) vulnerability
Details

Chainlit versions prior to 2.9.4 contain a server-side request forgery (SSRF) vulnerability in the /project/element update flow when configured with the SQLAlchemy data layer backend. An authenticated client can provide a user-controlled url value in an Element, which is fetched by the SQLAlchemy element creation logic using an outbound HTTP GET request. This allows an attacker to make arbitrary HTTP requests from the Chainlit server to internal network services or cloud metadata endpoints and store the retrieved responses via the configured storage provider.

Vulnerability from github – Published: 2026-02-11 14:23 – Updated: 2026-02-11 14:23
VLAI
Summary
LangChain affected by SSRF via image_url token counting in ChatOpenAI.get_num_tokens_from_messages
Details

Server-Side Request Forgery (SSRF) in ChatOpenAI Image Token Counting

Summary

The ChatOpenAI.get_num_tokens_from_messages() method fetches arbitrary image_url values without validation when computing token counts for vision-enabled models. This allows attackers to trigger Server-Side Request Forgery (SSRF) attacks by providing malicious image URLs in user input.

Severity

Low - The vulnerability allows SSRF attacks but has limited impact due to: - Responses are not returned to the attacker (blind SSRF) - Default 5-second timeout limits resource exhaustion - Non-image responses fail at PIL image parsing

Impact

An attacker who can control image URLs passed to get_num_tokens_from_messages() can: - Trigger HTTP requests from the application server to arbitrary internal or external URLs - Cause the server to access internal network resources (private IPs, cloud metadata endpoints) - Cause minor resource consumption through image downloads (bounded by timeout)

Note: This vulnerability occurs during token counting, which may happen outside of model invocation (e.g., in logging, metrics, or token budgeting flows).

Details

The vulnerable code path: 1. get_num_tokens_from_messages() processes messages containing image_url content blocks 2. For images without detail: "low", it calls _url_to_size() to fetch the image and compute token counts 3. _url_to_size() performs httpx.get(image_source) on any URL without validation 4. Prior to the patch, there was no SSRF protection, size limits, or explicit timeout

File: libs/partners/openai/langchain_openai/chat_models/base.py

Patches

The vulnerability has been patched in langchain-openai==1.1.9 (requires langchain-core==1.2.11).

The patch adds: 1. SSRF validation using langchain_core._security._ssrf_protection.validate_safe_url() to block: - Private IP ranges (RFC 1918, loopback, link-local) - Cloud metadata endpoints (169.254.169.254, etc.) - Invalid URL schemes 2. Explicit size limits (50 MB maximum, matching OpenAI's payload limit) 3. Explicit timeout (5 seconds, same as httpx.get default) 4. Allow disabling image fetching via allow_fetching_images=False parameter

Workarounds

If you cannot upgrade immediately:

  1. Sanitize input: Validate and filter image_url values before passing messages to token counting or model invocation
  2. Use network controls: Implement egress filtering to prevent outbound requests to private IPs
Severity
3.7 (Low)

Summary
Decidim: Push subscriptions can be abused for server-side requests
Details

Description

The push-subscription endpoint stores an attacker-controlled delivery URL, and the notification send path becomes an outbound-request sink when VAPID delivery is enabled. The practical result is an authenticated, stored, mostly blind SSRF primitive to arbitrary HTTPS endpoints reachable from the app server.

Technical description

When VAPID delivery is enabled, the notification subscription flow stores the client-supplied push endpoint without checking that it belongs to an approved push service. The send path later passes that stored URL to WebPush.payload_send, turning the subscription into an attacker-controlled outbound request destination. This is the source-to-sink chain:

  1. Source: attacker-controlled subscription.endpoint in the JSON body posted to POST /notifications_subscriptions.
  2. Persistence: params[:endpoint] is stored under user.notification_settings["subscriptions"].
  3. Retrieval: user.notifications_subscriptions.values returns that stored endpoint later.
  4. Sink: build_payload sets endpoint: subscription["endpoint"].
  5. Outbound request: WebPush.payload_send(**payload) uses the attacker-supplied endpoint as the destination.

One spec asserts that the endpoint is persisted exactly as supplied:

# decidim-core/spec/services/decidim/notifications_subscriptions_persistor_spec.rb
expect(user.notifications_subscriptions["auth_code_121"]["endpoint"]).to eq(params[:endpoint])

Another spec asserts that SendPushNotification passes the stored endpoint into WebPush.payload_send:

# decidim-core/spec/services/decidim/send_push_notification_spec.rb
first_notification_payload = {
  message:,

Impact

  • In a configured deployment, an authenticated user can register an attacker-controlled or otherwise unauthorized HTTPS URL.
  • The server then sends outbound POST requests there whenever a notification is pushed.
  • This is a stored, mostly blind SSRF primitive: useful for outbound interaction with attacker infrastructure and, where routable, internal HTTPS services.
  • Notification metadata is disclosed to the supplied endpoint through the encrypted web push request path.

Patches

See https://github.com/decidim/decidim/pull/16714.

Workarounds

Disable the push notifications feature by removing the VAPID keys in the server.

Resource

SSRF

Vulnerability from github – Published: 2026-04-22 00:31 – Updated: 2026-04-28 21:36
VLAI
Details

A server-side request forgery (SSRF) vulnerability was identified in GitHub Enterprise Server that allowed an attacker to extract sensitive environment variables from the instance through a timing side-channel attack against the notebook rendering service. When private mode was disabled, the notebook viewer followed HTTP redirects without revalidating the destination host, enabling an unauthenticated SSRF to internal services. By chaining this with regex filter queries against an internal API and measuring response time differences, an attacker could infer secret values character by character. Exploitation required that private mode be disabled and that the attacker be able to chain the instance's open redirect endpoint through an external redirect to reach internal services. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.21 and was fixed in versions 3.14.26, 3.15.21, 3.16.17, 3.17.14, 3.18.8, 3.19.5, and 3.20.1. This vulnerability was reported via the GitHub Bug Bounty program.

Details

Joomla Extension - svenbluege.de - Server-side request forgery in the Google Photos picker in Event Gallery extension < 6.6.0 - The Google Photos picker of the back-end upload page fetches the thumbnails of the picked images through the server, with the OAuth access token of the Google Photos account. The task took the address to fetch from the request without checking it and asked for no form token. A prepared page on another web site could therefore make the server send the access token of the account to any address, or fetch addresses inside the server's network, in the name of a logged in administrator; a back-end user with the permission "Manage" could do the same directly. The token is valid for about an hour and reaches what the picker session of the account reaches.

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.
