0.11.5

This patch release adds additional security guards against an ECDSA bug in Java SE versions 15-15.0.6, 17-17.0.2, and 18 (CVE-2022-21449) in addition to the guards added in the JJWT 0.11.3 release. This patch allows JJWT users using those JVM versions to upgrade to JJWT 0.11.5, even if they are unable to upgrade their JVM to patched/fixed JVM version in a timely manner. Note: if your application does not use these JVM versions, you are not exposed to the JVM vulnerability.

Note that the CVE is not a bug within JJWT itself - it is a bug within the above listed JVM versions, and the JJWT 0.11.5 release adds additional precautions within JJWT in case an application team is not able to upgrade their JVM in a timely manner.

However, even with these additional JJWT security guards, the root cause of the issue is the JVM, so it strongly recommended to upgrade your JVM to version 15.0.7, 17.0.3, or 18.0.1 or later to ensure the bug does not surface elsewhere in your application code or any other third party library in your application that may not contain similar security guards.

Issues included in this patch are listed in the JJWT 0.11.5 milestone.

Thank you to Neil Madden, the security researcher that first discovered the JVM vulnerability as covered in his Psychic Signatures in Java blog post. Neil worked directly with the JJWT team to provide these additional guards, beyond what was in the JJWT 0.11.3 release, and we're grateful for his help and collaboration in reviewing our fixes and for the additional tests he provided the JJWT team.

0.11.4

This patch release:

• Adds additional handling for rare JSON parsing exceptions and wraps them in a JwtException to allow the application to handle these conditions as JWT concerns.
• Upgrades the jjwt-jackson module's Jackson dependency to 2.12.6.1.
• Upgrades the jjwt-orgjson module's org.json:json dependency to 20220320.
• Upgrades the jjwt-gson module's gson dependency to 2.9.0.
• Upgrades the internal testing BouncyCastle version and any references in README documentation examples to 1.70.
• Contains various documentation and typo fixes.

The patch also makes various internal project POM and build enhancements to reduce repetition and the chance for stale references, and overall create a cleaner build with less warnings. It also ensures that CI testing builds and executes on all latest OpenJDK versions from Java 7 to Java 18 (inclusive).

Issues included in this patch are listed in the JJWT 0.11.4 milestone.
