How to Fix CVE-2023-26248

To remediate this vulnerability, upgrade all affected Github.com/libp2p/go libp2p kad dht 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/libp2p/go-libp2p-kad-dht fixed: Latest secure release 
Upgrade github.com/libp2p/go-libp2p-kad-dht to Latest secure release
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/libp2p/go-libp2p-kad-dht

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-26248, inspect your project dependencies for Github.com/libp2p/go libp2p kad dht:

inspect dependencies for github.com/libp2p/go-libp2p-kad-dht

Analyze the terminal output to locate any version of Github.com/libp2p/go libp2p kad dht in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), 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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Github.com/libp2p/go libp2p kad dht, 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

The Kademlia DHT (go-libp2p-kad-dht 0.20.0 and earlier) used in IPFS (0.18.1 and earlier) assigns routing information for content (i.e., information about who holds the content) to be stored by peers whose peer IDs have a small DHT distance from the content ID. This allows an attacker to censor content by generating many Sybil peers whose peer IDs have a small distance from the content ID, thus hijacking the content resolution process.
