Stored script injection via forged settings request
Published Oct 20, 2023 · Updated Apr 8, 2026
Cross-site request forgery in PluginUs.Net BEAR 1.1.3.3 and earlier allows remote attackers to inject stored scripts into plugin settings. The woobe_save_options function accepts state-changing requests without correct nonce validation and persists inadequately sanitized and escaped option input. Exploitation requires an authenticated site administrator to act on a crafted link or page, after which attacker-supplied script can execute in the affected administrative context.
