Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
prompts.chat prior to commit 30a8f04 contains a server-side request forgery vulnerability in the Fal.ai media status polling feature that allows authenticated users to perform arbitrary outbound requests by supplying attacker-controlled URLs in the token parameter. Attackers can exploit the lack of URL validation to disclose the FAL_API_KEY in the Authorization header, enabling credential theft, internal network probing, and abuse of the victim's Fal.ai account.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-918

The server can be induced to make requests to a URL an attacker controls, turning it into a proxy into internal networks and cloud metadata services. It's especially dangerous behind a trusted network boundary. The fix is strict allow-listing of destinations and blocking access to internal address ranges.

Update to the code version after commit 30a8f0470e0ba45e6be9c9f55220f4a9a6b91c99 (any version post-2026-03-25)

  1. 1. Navigate to the prompts.chat repository: https://github.com/f/prompts.chat
  2. 2. Locate the commit 30a8f0470e0ba45e6be9c9f55220f4a9a6b91c99 in the commit history
  3. 3. Review the changes made in the commit to understand the SSRF fix implementation
  4. 4. Apply the fix by either pulling the latest code after commit 30a8f04 or cherry-picking the commit
  5. 5. Verify that the fix includes proper URL validation for the Fal.ai token parameter to prevent SSRF attacks
  6. 6. After applying the patch, ensure the FAL_API_KEY is no longer exposed in outbound requests to user-controlled URLs
  7. 7. Test the Fal.ai media status polling feature to confirm it only allows legitimate Fal.ai API endpoints
