CVE-2026-54223
UBB.threads is vulnerable to Path traversal, allowing attackers with privilege to edit templates to read and write any file on the application’s server that application has privileges to, what results in Remote Code Execution.
Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.
