GitBucket 4.23.1 contains an unauthenticated remote code execution vulnerability that allows attackers to execute arbitrary commands by exploiting weak secret token generation and insecure file upload functionality. Attackers can brute-force the Blowfish encryption key, upload a malicious JAR plugin via the git-lfs endpoint, and execute system commands through an exposed exploit endpoint.
