This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The bypass relies on hex-encoded shortcode attribute payloads (e.g. \x3cscript\x3e), which wp_kses_post cannot strip on save because they appear as literal backslash sequences rather than real HTML tags; WordPress core&#39;s shortcode_parse_atts() then calls stripcslashes() at render time, decoding the escapes into real angle brackets before they reach the unescaped sink.</p> <p><strong>Affected:</strong> joedolson My Calendar – Accessible Event Manager</p> <p>The My Calendar – Accessible Event Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via &#39;fallback&#39; Shortcode Attribute in all versions up to, and including, 3.8.3 due to insufficient input sanitization and output escaping.
