How to Fix GHSA-jqx4-9gpq-rppm

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

@misskey-dev/summaly fixed: 5.2.1 
npm install @misskey-dev/summaly@5.2.1
Verify Direct and Transitive Dependencies

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

npm ls @misskey-dev/summaly

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-jqx4-9gpq-rppm, inspect your project dependencies using npm:

npm ls @misskey-dev/summaly

Analyze the terminal output to locate any version of @misskey dev/summaly in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.2.1), your application is affected.

Note: The npm ls @misskey-dev/summaly command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-346: Origin Validation Error, where the product does not properly verify that the source of data or communication is valid. In @misskey dev/summaly, 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 Due to a validation error in `got.scpaping`, it is possible to use an HTTP redirect to avoid IP filtering. ### Details In `got.scpaping`, Summaly first makes a HTTP `HEAD` request to the page being summarized. It then preforms private IP address checks on the `HEAD` response, then makes an additional HTTP `GET` request to the page being summarized. Unfortunately, since private IP address checks aren't performed on the `GET` response, the `GET` response can issue a HTTP redirect to a private IP address, which will succeed, regardless of if private IP addresses are allowed by Summaly. ### PoC With a simple Caddy webserver, you can get Summaly to summarize a page hosted via a local IP address: ```caddy @summaly-bypass-head { method HEAD path /summaly-bypass } @summaly-bypass-get { method GET path /summaly-bypass } header @summaly-bypass-head Content-Type "text/html" respond @summaly-bypass-head 200 redir @summaly-bypass-get http://127.0.0.1:3080/ ``` ### Impact Using this bypass, an attacker can probe a victims internal network for HTTP services that aren't supposed to be exposed to the outside world. While they might only have read-only access through this, it may still be possible to extract sensitive information or be used to probe a network prior to attacking via other exploits without leaving a trace.
