CVE-2026-25559

OpenBullet2 through version 0.3.2 contains a path traversal vulnerability in the wordlist endpoint that allows authenticated attackers to perform arbitrary file read, write, and delete operations by supplying unsanitized absolute paths to the upload handler and wordlist functions. Attackers can chain the file write and delete primitives to achieve remote code execution by manipulating critical system files such as /etc/passwd, with full system impact since the application runs as root by default.
