      <title>CVE-2026-33683 — AVideo vulnerable to Stored XSS via html_entity_decode() Reversing xss_esc() Sanitization in Channel About Field</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-33683</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; WWBN AVideo&lt;/p&gt;
&lt;p&gt;WWBN AVideo is an open source video platform. In versions up to and including 26.0, a sanitization order-of-operations flaw in the user profile &amp;#34;about&amp;#34; field allows any registered user to inject arbitrary JavaScript that executes when other users visit their channel page. The `xss_esc()` function entity-encodes input before `strip_specific_tags()` can match dangerous HTML tags, and `html_entity_decode()` on output reverses the encoding, restoring the raw malicious HTML. Commit 7cfdc380dae1e56bbb5de581470d9e9957445df0 contains a patch.&lt;/p&gt;</description>
