X5.0 CAPTCHA Bypass via Predictable Character Set https://db.gcve.eu/vuln/cve-2026-49953 <p><strong>Affected:</strong> Discuz! X5.0</p> <p>Discuz! X5.0 releases 20260320 through 20260610 contains a CAPTCHA bypass vulnerability that allows unauthenticated remote attackers to defeat challenge controls by exploiting limited complexity and predictable character sets in generated CAPTCHA images. Attackers can train a custom optical character recognition model against collected CAPTCHA samples to reliably predict challenge text, bypassing protections on login, registration, and other functionality from automated abuse.</p> <p><strong>Affected:</strong> Discuz!
