libjwt3: LibJWT is a C JSON Web Token Library
CVE-2026-33996 is fixed in libjwt3 on 1 platform by DEBIAN-CVE-2026-33996 (version 3.3.2-1), released March 27, 2026. It is not reported as exploited. Patch Radar priority: Routine.
LibJWT is a C JSON Web Token Library. Starting in version 3.0.0 and prior to version 3.3.0, the JWK parsing for RSA-PSS did not protect against a NULL value when expecting to parse JSON string values. A specially crafted JWK file could exploit this behavior by using integers in places where the code expected a string. This was fixed in v3.3.0. A workaround is available. Users importing keys through a JWK file should not do so from untrusted sources. Use the `jwk2key` tool to check for validity of a JWK file. Likewise, if possible, do not use JWK files with RSA-PSS keys.
