Vulnerability Data

WWBN AVideo is an open source video platform. Prior to version 26.0, WWBN/AVideo contains an open redirect vulnerability in the login flow where a user-supplied redirectUri parameter is reflected directly into a JavaScript `document.location` assignment without JavaScript-safe encoding. After a…

user completes the login popup flow, a timer callback executes the redirect using the unvalidated value, sending the victim to an attacker-controlled site. Version 26.0 fixes the issue.

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation of the untrusted redirectUri parameter before it is used in a client-side location assignment, blocking the open redirect.

AC-4 Information Flow Enforcement partial match
prevent

Enforces policy-based information flow rules that can restrict allowed redirect targets to an approved set of domains.

SI-15 Information Output Filtering partial match
prevent

Filters untrusted output values (the redirect URI) before they are written into executable JavaScript context.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and untrusted-redirect controls that prevent CWE-601.

A.8.23 Web filtering partial match
mitigates

Preventing access to attacker-controlled or malicious sites stops users from being redirected to untrusted locations via open-redirect or phishing links.
