Title
AVideo's GET-Based CSRF in setPermission.json.php Enables Privilege Escalation via Arbitrary Permission Modification
Summary
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `plugin/Permissions/setPermission.json.php` endpoint accepts GET parameters for a state-changing operation that modifies user group permissions. The endpoint has no CSRF token validation, and the application explicitly sets `session.cookie_samesite=None` on session cookies. This allows an unauthenticated attacker to craft a page with `<img>` tags that, when visited by an admin, silently grant arbitrary permissions to the attacker's user group — escalating the attacker to near-admin access. As of time of publication, no known patched versions are available.

Title
Emlog: CSRF in Backend Upgrade Interface Leading to Arbitrary Remote SQL Execution and Arbitrary File Write
Summary
Emlog is an open source website building system. Prior to version 2.6.8, the backend upgrade interface accepts remote SQL and ZIP URLs via GET parameters. The server first downloads and executes the SQL file, then downloads the ZIP file and extracts it directly into the web root directory. This process does not validate a CSRF token. Therefore, an attacker only needs to trick an authenticated administrator into visiting a malicious link to achieve arbitrary SQL execution and arbitrary file write. This issue has been patched in version 2.6.8.

Admidio: Missing CSRF Protection on Custom List Deletion in mylist_function.php
Summary
Admidio is an open-source user management solution. From version 5.0.0 to before version 5.0.8, the delete mode handler in mylist_function.php permanently deletes list configurations without validating a CSRF token. An attacker who can lure an authenticated user to a malicious page can silently destroy that user's list configurations — including organization-wide shared lists when the victim holds administrator rights. This issue has been patched in version 5.0.8.

Admidio: CSRF and Form Validation Bypass in Inventory Item Save via `imported` Parameter
Summary
Admidio is an open-source user management solution. Prior to version 5.0.8, the inventory module's item_save endpoint accepts a user-controllable POST parameter imported that, when set to true, completely bypasses both CSRF token validation and server-side form validation. An authenticated user can craft a direct POST request to save arbitrary inventory item data without CSRF protection and without the field value checks that the FormPresenter validation normally enforces. This issue has been patched in version 5.0.8.

Title
Admidio: Missing CSRF Protection on Registration Approval Actions
Summary
Admidio is an open-source user management solution. Prior to version 5.0.8, the create_user, assign_member, and assign_user action modes in modules/registration.php approve pending user registrations via GET request without validating a CSRF token. Unlike the delete_user mode in the same file (which correctly validates the token), these three approval actions read their parameters from $_GET and perform irreversible state changes without any protection. An attacker who has submitted a pending registration can extract their own user UUID from the registration confirmation email URL, then trick any user with the rol_approve_users right into visiting a crafted URL that automatically approves the registration. This bypasses the manual registration approval workflow entirely. This issue has been patched in version 5.0.8.

Unlike the delete_user mode in the same file (which correctly validates the token), these three approval actions read their parameters from $_GET and perform irreversible state changes without any protection. An attacker who has submitted a pending registration can extract their own user UUID from the registration confirmation email URL, then trick any user with the rol_approve_users right into visiting a crafted URL that automatically approves the registration. This bypasses the manual registration approval workflow entirely. This issue has been patched in version 5.0.8."

Title
AVideo: CSRF on Admin Plugin Configuration Enables Payment Credential Hijacking
Summary
WWBN AVideo is an open source video platform. In versions 26.0 and prior, AVideo's admin plugin configuration endpoint (admin/save.json.php) lacks any CSRF token validation. There is no call to isGlobalTokenValid() or verifyToken() before processing the request. Combined with the application's explicit SameSite=None cookie policy, an attacker can forge cross-origin POST requests from a malicious page to overwrite arbitrary plugin settings on a victim administrator's session. Because the plugins table is included in the ignoreTableSecurityCheck() array in objects/Object.php, standard table-level access controls are also bypassed. This allows a complete takeover of platform functionality by reconfiguring payment processors, authentication providers, cloud storage credentials, and more. At time of publication, there are no publicly available patches.

NamelessMC: OAuth callback `state` is not validated, allowing login CSRF / session swapping
Summary
NamelessMC is website software for Minecraft servers. In versions 2.2.4 and prior, the OAuth callback handling does not validate the state parameter server-side before exchanging the authorization code. This allows an attacker to capture a valid OAuth callback URL for their own account and cause a victim's browser to navigate to it, resulting in the victim's session being authenticated as the attacker-linked account (OAuth login CSRF / session swapping). This is patched in version 2.2.5.

AVideo: CSRF on emailAllUsers.json.php Enables Mass Phishing Email to All Users
Summary
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the AVideo endpoint objects/emailAllUsers.json.php allows administrators to send HTML emails to every registered user on the platform. While the endpoint verifies admin session status, it does not validate a CSRF token. Because AVideo sets SameSite=None on session cookies, a cross-origin POST request from an attacker-controlled page will include the admin's session cookie automatically. An attacker who lures an admin to a malicious page can send an arbitrary HTML email to every user on the platform, appearing to originate from the instance's legitimate SMTP address. At time of publication, there are no publicly available patches.

Title
AVideo: CSRF on Plugin Enable/Disable Endpoint Allows Disabling Security Plugins
Summary
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the AVideo endpoint objects/pluginSwitch.json.php allows administrators to enable or disable any installed plugin. The endpoint checks for an active admin session but does not validate a CSRF token. Additionally, the plugins database table is explicitly listed in ignoreTableSecurityCheck(), which means the ORM-level Referer/Origin domain validation in ObjectYPT::save() is also bypassed. Combined with SameSite=None on session cookies, an attacker can disable critical security plugins (such as LoginControl for 2FA, subscription enforcement, or access control plugins) by luring an admin to a malicious page. At time of publication, there are no publicly available patches.

Mitigation ID: MIT-4
Phase: Architecture and Design
Strategy: Libraries or Frameworks
Description:
- 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
Phase: Implementation
Description:
- 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
Phase: Architecture and Design
Description:
- 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
Phase: Architecture and Design
Description:
- 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
Phase: Architecture and Design
Description:
- 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
Phase: Architecture and Design
Description:
- Do not use the GET method for any request that triggers a state change.
Mitigation
Phase: Implementation
Description:
- 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.
