CVE-2016-5429

Status: ModifiedLow (3.7)—

jose-php before 2.2.1 does not use constant-time operations for HMAC comparison, which makes it easier for remote attackers to obtain sensitive information via a timing attack, related to JWE.php and JWS.php.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
