YesWiki, a PHP-based wiki system, contains a stored cross-site scripting vulnerability in its comments feature. This flaw allows attackers to inject malicious JavaScript payloads that are stored and executed whenever a user views the affected comment. The vulnerability arises from improper sanitization and encoding of user input, specifically failing to account for obfuscated script payloads using JavaScript block comments.
