Summary
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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
