0 Net::OAuth versions before 0.33 for Perl use a non-constant-time comparison when verifying HMAC-SHA1, HMAC-SHA256, and PLAINTEXT signatures. This timing discrepancy allows an attacker who can submit messages and measure response times to recover valid signatures byte-by-byte. The PLAINTEXT method is particularly vulnerable as it compares against the signature key itself, potentially exposing consumer_secret and token_secret. RSA-SHA1 verification is not affected. The vulnerability has a high severity with a CVSS score of 7.5. Join the discussion | CVE Database V5 | 08/19/2026, 07:20:44 UTC Added: 08/19/2026, 07:34:54 UTC |
