CVE-2023-48708Network attack vector

Account impersonation via raw token logging

Published Nov 24, 2023 · Updated Aug 2, 2024

Sensitive-data exposure in CodeIgniter Shield before 1.0.0-beta.8 allows attackers with log-table access to obtain raw tokens. The AccessTokens and HmacSha256 authenticators pass submitted credentials to recordLoginAttempt, while JWT passes them before the patch substitutes token names or SHA-256 hashes. Successful-attempt logging must be enabled, and reading the log table permits requests with the affected user's authority.
