GHSA-4Q27-4RRQ-FX95
Vulnerability from github – Published: 2026-04-03 23:43 – Updated: 2026-04-06 23:43Severity: Medium CWE: CWE-352 (Cross-Site Request Forgery)
Summary
The player skin configuration endpoint at admin/playerUpdate.json.php does not validate CSRF tokens. The plugins table is explicitly excluded from the ORM's domain-based security check via ignoreTableSecurityCheck(), removing the only other layer of defense. Combined with SameSite=None cookies, a cross-origin POST can modify the video player appearance on the entire platform.
Details
In admin/playerUpdate.json.php at line 17, the player skin is set directly from POST data:
$pluginDO->skin = $_POST['skin'];
No CSRF token is validated anywhere in the endpoint. Normally, the ORM layer performs a Referer/Origin domain check as a secondary defense against cross-origin writes. However, the plugins table is registered in ignoreTableSecurityCheck(), which explicitly bypasses this ORM-level protection for plugin configuration.
AVideo's session cookies are configured with SameSite=None, meaning the admin's authenticated session cookie is automatically included in cross-origin POST requests from any website.
An attacker can craft a page that, when visited by an authenticated admin, silently changes the player skin to any value, including potentially invalid or disruptive configurations.
Proof of Concept
Host the following HTML on an attacker-controlled domain:
<!DOCTYPE html>
<html>
<head><title>CSRF Player Skin</title></head>
<body>
<h1>Loading video...</h1>
<form id="csrf" method="POST"
action="https://your-avideo-instance.com/admin/playerUpdate.json.php">
<input type="hidden" name="skin" value="minimalist" />
</form>
<script>
document.getElementById("csrf").submit();
</script>
</body>
</html>
When an authenticated admin visits this page, the platform's player skin is changed without their knowledge.
Impact
- Platform-wide player appearance modification without admin consent
- Potential disruption of video playback if an invalid skin value is set
- The ORM security bypass via
ignoreTableSecurityCheck()means there is no fallback protection - Can be used as part of a broader defacement or social engineering attack
Recommended Fix
Add CSRF token validation at admin/playerUpdate.json.php, before processing POST data:
// admin/playerUpdate.json.php (before line 17)
if (!isGlobalTokenValid()) {
die('{"error":"Invalid CSRF token"}');
}

Mitigation MIT-4
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
- For example, use anti-CSRF packages such as the OWASP CSRFGuard. [REF-330]
- Another example is the ESAPI Session Management control, which includes a component for CSRF. [REF-45]
Mitigation
Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
Mitigation
Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330). [REF-332]
Mitigation
Identify especially dangerous operations. When the user performs a dangerous operation, send a separate confirmation request to ensure that the user intended to perform that operation.
Mitigation
- Use the "double-submitted cookie" method as described by Felten and Zeller:
- When a user visits a site, the site should generate a pseudorandom value and set it as a cookie on the user's machine. The site should require every form submission to include this value as a form value and also as a cookie value. When a POST request is sent to the site, the request should only be considered valid if the form value and the cookie value are the same.
- Because of the same-origin policy, an attacker cannot read or modify the value stored in the cookie. To successfully submit a form on behalf of the user, the attacker would have to correctly guess the pseudorandom value. If the pseudorandom value is cryptographically strong, this will be prohibitively difficult.
- This technique requires Javascript, so it may not work for browsers that have Javascript disabled. [REF-331]
Mitigation
Do not use the GET method for any request that triggers a state change.
Mitigation
Check the HTTP Referer header to see if the request originated from an expected page. This could break legitimate functionality, because users or proxies may have disabled sending the Referer for privacy reasons.
CAPEC-111: JSON Hijacking (aka JavaScript Hijacking)
An attacker targets a system that uses JavaScript Object Notation (JSON) as a transport mechanism between the client and the server (common in Web 2.0 systems using AJAX) to steal possibly confidential information transmitted from the server back to the client inside the JSON object by taking advantage of the loophole in the browser's Same Origin Policy that does not prohibit JavaScript from one website to be included and executed in the context of another website.
CAPEC-462: Cross-Domain Search Timing
An attacker initiates cross domain HTTP / GET requests and times the server responses. The timing of these responses may leak important information on what is happening on the server. Browser's same origin policy prevents the attacker from directly reading the server responses (in the absence of any other weaknesses), but does not prevent the attacker from timing the responses to requests that the attacker issued cross domain.
CAPEC-467: Cross Site Identification
An attacker harvests identifying information about a victim via an active session that the victim's browser has with a social networking site. A victim may have the social networking site open in one tab or perhaps is simply using the "remember me" feature to keep their session with the social networking site active. An attacker induces a payload to execute in the victim's browser that transparently to the victim initiates a request to the social networking site (e.g., via available social network site APIs) to retrieve identifying information about a victim. While some of this information may be public, the attacker is able to harvest this information in context and may use it for further attacks on the user (e.g., spear phishing).
CAPEC-62: Cross Site Request Forgery
An attacker crafts malicious web links and distributes them (via web pages, email, etc.), typically in a targeted manner, hoping to induce users to click on the link and execute the malicious action against some third-party application. If successful, the action embedded in the malicious link will be processed and accepted by the targeted application with the users' privilege level. This type of attack leverages the persistence and implicit trust placed in user session cookies by many web applications today. In such an architecture, once the user authenticates to an application and a session cookie is created on the user's system, all following transactions for that session are authenticated using that cookie including potential actions initiated by an attacker and simply "riding" the existing session cookie.
