Cloudinary is a SaaS/API provider that streamlines a website's entire image management pipeline. Cloudinary strives to be the standard for online images acquisition, manipulation and delivery.
Using Cloudinary you can easily move all your website’s images and other assets to the cloud. Automatically perform smart image resizing, cropping, merging, overlay, watermark, apply effects, rotations and perform format conversions. All this without installing any complex software. Integrate Facebook, Twitter, Google+ and Gravatar profile image extraction in a snap, fetch images from any online resource in any dimension and style to match your website’s graphics requirements, and much more. Simply put, if you have images in your web or mobile app, let Cloudinary manage them for you.
Cloudinary offers comprehensive APIs and administration capabilities and is easy to integrate with any web application. To simplify integration further we also have client libraries for Ruby on Rails, Python/Django, PHP, .NET, Node.js and more. In addition, alternative integration methods allow non-developers, bloggers and website administrators to enjoy Cloudinary with nearly zero code changes.
For the initial prioritization/rating of findings, this program will use the Bugcrowd Vulnerability Rating Taxonomy. However, it is important to note that in some cases a vulnerability priority will be modified due to its likelihood or impact. In any instance where an issue is downgraded, a full, detailed explanation will be provided to the researcher - along with the opportunity to appeal, and make a case for a higher priority.
We are particularly interested and will consider extraordinary submissions around:
- Major exposures around customer data leak
- Issues that result in full compromise of a system (RCE, etc.)
- Business logic bypasses resulting in significant impact
- Major operational failure

- Cloudinary has built-in functionality to fetch remote URLs to read remote files into the system, via fetch URL (http://res.cloudinary.com/demo/image/fetch/<remote url>), via the upload API's URL parameter (https://cloudinary.com/documentation/image_upload_api_reference#upload) and in other places in the API. This functionality as it's meant to be used will not be considered an SSRF vulnerability when allowing access to external servers, even though it might be used to anonymously scan other web servers for vulnerabilities or open ports other than common web ports. We will accept disclosures that show how this functionality is used to access internal networks or external services having significant security or DOS impact.
