Summary

robbert229/jwt's token validation methods vulnerable to a timing side-channel during HMAC comparison

Details

Token validation methods are susceptible to a timing side-channel during HMAC comparison. With a large enough number of requests over a low latency connection, an attacker may use this to determine the expected HMAC.

Severity

7.5 (High)

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.
