The HashiCorp cap JWT validation library before version 0.14.0 is vulnerable to a claims validation bypass that may cause downstream applications to make authorization decisions using claim values different from those validated. Exploitation requires attacker-controlled claims in a JWT signed by a key trusted by the application. This vulnerability (CVE-2026-19194) is fixed in cap 0.14.0.
