    CVE-2026-54224 (GCVE-0-2026-54224)

    Vulnerability from cvelistv5 – Published: 2026-06-18 12:56 – Updated: 2026-06-18 13:09
    VLAI
    Title
    Denial of Service in UBB.threads
    Summary
    UBB.threads is vulnerable to Denial of Service (DoS). By sending multiple concurrent requests to view any user profile on instances with many registered users, an authenticated attacker can easily exhaust database resources and completely deny access to the application for other users. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.

    CVE-2026-54222 (GCVE-0-2026-54222)

    Vulnerability from cvelistv5 – Published: 2026-06-18 12:56 – Updated: 2026-06-18 13:12
    VLAI
    Title
    Blind SQL Injection in UBB.threads
    Summary
    UBB.threads is vulnerable to Blind SQL Injection, allowing attackers with access to the Members in Control Panel to interact with the underlying database. Due to insufficient input sanitization, an attacker can extract sensitive information, such as user credentials, by manipulating SQL queries through time-based or boolean-based techniques. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.

    Title
    Reflected XSS in UBB.threads
    Summary
    UBB.threads is vulnerable to Reflected XSS. The application improperly handles user input in certain requests, enabling attackers to execute arbitrary JavaScript in the context of a victim's browser by tricking them into clicking a crafted link.  Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.

    Title
    Stored XSS in UBB.threads
    Summary
    UBB.threads is vulnerable to Stored XSS via user posts and user profile fields. The application fails to properly sanitize user input, allowing low privileged attackers to inject arbitrary JavaScript that executes in a victim's browser upon viewing. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.
