How to Fix CVE-2025-24354

To remediate this vulnerability, upgrade all affected Github.com/imgproxy/imgproxy dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/imgproxy/imgproxy fixed: 3.27.2 
Upgrade github.com/imgproxy/imgproxy to 3.27.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/imgproxy/imgproxy

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-24354, inspect your project dependencies for Github.com/imgproxy/imgproxy:

inspect dependencies for github.com/imgproxy/imgproxy

Analyze the terminal output to locate any version of Github.com/imgproxy/imgproxy in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.27.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where 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. In Github.com/imgproxy/imgproxy, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary Imgproxy does not block the `0.0.0.0` address, even with `IMGPROXY_ALLOW_LOOPBACK_SOURCE_ADDRESSES` set to false. This can expose services on the local host. ### Details imgproxy protects against SSRF against a loopback address with the following check ([source](https://github.com/imgproxy/imgproxy/blob/0f37d62fd8326a32c213b30dd52e2319770885d8/security/source.go#L43C1-L47C1)): ``` if !config.AllowLoopbackSourceAddresses && ip.IsLoopback() { return ErrSourceAddressNotAllowed } ``` This check is insufficient to prevent accessing services on the local host, as services may receive traffic on `0.0.0.0`. Go's `IsLoopback` ([source](https://github.com/golang/go/blob/40b3c0e58a0ae8dec4684a009bf3806769e0fc41/src/net/ip.go#L126-L131)) strictly follows the definition of loopback IPs beginning with `127`. `0.0.0.0` is not blocked.
