CVE-2026-59256

AVideo is an open source video platform that is vulnerable to SSRF attacks in versions up to 29.0. Two endpoints improperly validate user-supplied URLs, allowing an attacker to redirect to internal resources.

AVideo is an open-source video platform that, in versions up to 29.0, exposes the local CloneSite shared secret in the HTTP response to every unauthenticated request. This secret can be exploited by an attacker to impersonate the victim and gain access to the remote database.

AVideo is an open-source video platform that has a vulnerability in versions up to 29.0 allowing an unauthenticated attacker to send malicious messages via WebSocket. This vulnerability arises from improper JSON data handling, enabling PHP code execution on the server.

AVideo has an unauthenticated arbitrary file write vulnerability in the aVideoEncoderChunk.json.php endpoint, allowing remote attackers to write up to 4 GB of arbitrary content via HTTP PUT without authentication.

AVideo before 29.0 contains an incomplete fix for CVE-2026-45578. execAsync() re-wraps escaped commands in double-quoted sh -c, allowing command substitution via $() and backticks. Attackers can inject arbitrary OS commands through the Live plugin on_publish.php endpoint despite escapeshellarg() protection.

WWBN AVideo before version 29.0 contains a stored DOM Cross-Site Scripting vulnerability in the YPTSocket plugin. An unauthenticated remote attacker can execute arbitrary JavaScript in the context of an administrator viewing the online users debug panel.

AVideo versions 14.3.1 prior to 20.1 contain an unauthenticated remote code execution vulnerability caused by predictable generation of an installation salt using PHP uniqid(). The installation timestamp is exposed via a public endpoint, and a derived hash identifier is accessible through unauthenticated API responses, allowing attackers to brute-force the remaining entropy. The recovered salt can then be used to encrypt a malicious payload supplied to a notification API endpoint that evaluates attacker-controlled input, resulting in arbitrary code execution as the web server user.

AVideo versions prior to 20.1 with the ImageGallery plugin enabled is vulnerable to unauthenticated file upload and deletion. Plugin endpoints responsible for managing gallery images fail to enforce authentication checks and do not validate ownership, allowing unauthenticated attackers to upload or delete images associated with any image-based video.

WWBN AVideo through 30.0 (and master up to commit 4cb576e) contains a cross-site request forgery vulnerability in plugin/Live/myLiveControls.save.json.php. The endpoint only checks that a user is logged in and processes customUrl, customMessage, and autoRedirect parameters from $_REQUEST via a GET request without enforcing a CSRF token or origin check. An attacker who lures a logged-in streamer to a malicious page can silently change the live-channel viewer-redirect settings, causing viewers to be redirected to a phishing site or shown a spoofed message.

WWBN AVideo through version 30.0 fails to enforce authentication on the report4.json.php and report4.1.json.php endpoints, allowing unauthenticated access to user registration statistics. Attackers can send GET requests to these endpoints to retrieve daily and cumulative user-registration counts without any session or authorization.
