WWBN AVideo Multiple Vulnerabilities

WWBN AVideo versions up to and including 26.0 contain an authentication bypass vulnerability in the standalone live stream control endpoint. The endpoint accepts a user-supplied 'streamerURL' parameter that redirects token verification to an attacker-controlled server, allowing complete bypass of authentication without any user interaction. With a CVSS score of 9.4, an attacker gains unauthenticated control over any live stream including the ability to drop publishers, manipulate recordings, and probe stream existence.

WWBN AVideo versions up to and including 26.0 contain a critical file upload vulnerability in the ImageGallery::saveFile() method that allows authenticated attackers to upload polyglot files (JPEG with embedded PHP code) and achieve Remote Code Execution. The vulnerability exploits a mismatch between MIME type validation (which checks file content) and filename extension handling (which trusts user input), allowing attackers to bypass security controls and execute arbitrary code on the server. A patch is available in commit 345a8d3ece0ad1e1b71a704c1579cbf885d8f3ae, and the issue has been publicly disclosed via GitHub Security Advisory GHSA-wxjw-phj6-g75w.

WWBN AVideo versions up to and including 26.0 contain a command injection vulnerability in the restreamer endpoint that allows authenticated attackers to execute arbitrary commands on the server. The vulnerability stems from unsanitized user input (users_id and liveTransmitionHistory_id parameters) being embedded directly into shell commands via exec(). With a CVSS score of 8.8, this critical vulnerability requires low attack complexity and low privileges, enabling complete system compromise including data theft, modification, and denial of service.

WWBN AVideo versions up to and including 26.0 contain a critical file upload vulnerability (CWE-434) that allows authenticated attackers to upload and execute arbitrary PHP code on the server. The vulnerability exists in the downloadVideoFromDownloadURL() function which saves remote content with its original filename and extension to a web-accessible directory; by providing an invalid resolution parameter, attackers can bypass cleanup mechanisms, leaving executable PHP files persistent under the web root. With a CVSS score of 8.8, this represents a high-severity remote code execution risk for authenticated users.

WWBN AVideo versions up to and including 26.0 contain an unauthenticated path traversal vulnerability in the locale API endpoint that allows arbitrary PHP file inclusion under the web root. Attackers can achieve confirmed file disclosure and code execution by including existing PHP files, with potential escalation to full remote code execution if they can upload or control PHP files elsewhere in the application tree. The vulnerability has a CVSS score of 8.6 and requires no authentication or user interaction to exploit, though no patch is currently available and there is no evidence of active exploitation in KEV data.

WWBN AVideo video platform up to and including version 26.0 contains an authentication bypass vulnerability in the CDN plugin that allows unauthenticated remote attackers to completely modify CDN configuration settings including storage credentials and authentication keys. The vulnerability stems from the CDN plugin's default empty string authentication key, which causes validation checks to be bypassed entirely when the plugin is enabled but not properly configured. The CVSS score of 8.6 reflects high integrity impact with network-based exploitation requiring no privileges or user interaction.

A Cross-Site Request Forgery (CSRF) vulnerability in WWBN AVideo open source video platform versions up to and including 26.0 allows unauthenticated attackers to escalate privileges to near-admin access by tricking an administrator into visiting a malicious page. The vulnerability exists in the setPermission.json.php endpoint which accepts state-changing operations via GET requests without CSRF token validation, compounded by the application's explicit SameSite=None cookie setting. No patched version is currently available, and with a CVSS score of 8.1 (High), this represents a significant risk for installations with administrative users who browse external content.

SQL injection in WWBN AVideo up to version 26.0 allows authenticated users to extract arbitrary database contents through time-based blind SQL injection via the remindMe.json.php endpoint. The vulnerability stems from insufficient input sanitization of the live_schedule_id parameter, which is concatenated directly into a SQL LIKE clause despite partial validation in intermediate functions. No patch is currently available.

Privilege escalation in WWBN AVideo up to version 26.0 allows users with "Videos Moderator" permissions to gain full video management capabilities, including transferring ownership and deleting any video, by exploiting inconsistent authorization checks between the video editing and deletion endpoints. An authenticated attacker can chain an ownership transfer with deletion operations to compromise videos outside their legitimate scope. A patch is available in commit 838e16818c793779406ecbf34ebaeba9830e33f8.

WWBN AVideo versions up to and including 26.0 contain an unauthenticated API endpoint that allows arbitrary decryption of ciphertext. Attackers can exploit the decryptString action in the API plugin without authentication to decrypt publicly-issued ciphertext (such as from view/url2Embed.json.php), allowing recovery of protected tokens and metadata. The CVSS score of 7.5 reflects high confidentiality impact with network accessibility and no authentication required.

WWBN AVideo, an open source video platform, contains a critical path traversal vulnerability in the pluginRunDatabaseScript.json.php endpoint that allows authenticated administrators to execute arbitrary SQL queries against the application database. Versions up to and including 26.0 are affected. The vulnerability can also be exploited via CSRF attacks against authenticated admin sessions, enabling unauthenticated attackers to achieve remote code execution or complete database compromise.

WWBN AVideo, an open source video platform, contains a SQL injection vulnerability in the Subscribe::save() method that allows authenticated attackers to execute arbitrary SQL queries. Versions up to and including 26.0 are affected, with the vulnerability stemming from unsanitized user input from the $_POST['user_id'] parameter being concatenated directly into INSERT queries. An attacker with low-level authentication can extract sensitive data including password hashes, API keys, and encryption salts from the database, representing a significant information disclosure risk.

WWBN AVideo versions up to and including 26.0 contain a stored cross-site scripting (XSS) vulnerability in the user profile "about" field caused by improper sanitization order of operations. Any registered user can inject arbitrary JavaScript that executes when other users visit their channel page, allowing attackers to steal session cookies, perform actions on behalf of victims, or redirect users to malicious sites. A patch is available via commit 7cfdc380dae1e56bbb5de581470d9e9957445df0, and the vulnerability has been formally disclosed through GitHub Security Advisory GHSA-ghx5-7jjg-q2j7.

WWBN AVideo versions up to and including 26.0 contain an information disclosure vulnerability in the password recovery endpoint (objects/userRecoverPass.php) that allows unauthenticated attackers to enumerate valid usernames and determine account status (active, inactive, or banned) without solving any captcha. The vulnerability exists because user existence and account status validation occurs before captcha verification, enabling attackers to distinguish three different JSON error responses at scale. No evidence of active exploitation in the wild has been reported, but a patch is available in commit e42f54123b460fd1b2ee01f2ce3d4a386e88d157.
