Detailsinfo

A vulnerability was found in Auto Upload Images Plugin up to 3.3.2. It has been classified as critical. This affects the function downloadImage. The manipulation with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The Auto Upload Images plugin for WordPress is vulnerable to Limited Server-Side Request Forgery in all versions up to, and including, 3.3.2 via the downloadImage function. This makes it possible for authenticated attackers, with contributor-level access and above, to make web requests to arbitrary locations originating from the web application. The plugin uses wp_remote_get() rather than wp_safe_remote_get(), and the validate() method only rejects URLs whose host matches the site's own hostname, failing to block requests to private, loopback, or link-local addresses (e.g., 127.0.0.1, 10.0.0.0/8, 169.254.169.254). Attackers can trigger this by embedding a crafted <img> tag with a src attribute pointing to internal network hosts in post content and submitting it for processing.
