WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `objects/pluginRunDatabaseScript.json.php` endpoint accepts a `name` parameter via POST and passes it to `Plugin::getDatabaseFileName()` without any path traversal sanitization. This allows an authenticated admin (or an attacker via CSRF) to traverse outside the plugin directory and execute the contents of any `install/install.sql` file on the filesystem as raw SQL queries against the application database. Commit 81b591c509835505cb9f298aa1162ac64c4152cb contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `remindMe.json.php` endpoint passes `$_REQUEST['live_schedule_id']` through multiple functions without sanitization until it reaches `Scheduler_commands::getAllActiveOrToRepeat()`, which directly concatenates it into a SQL `LIKE` clause. Although intermediate functions (`new Live_schedule()`, `getUsers_idOrCompany()`) apply `intval()` internally, they do so on local copies within `ObjectYPT::getFromDb()`, leaving the original tainted variable unchanged. Any authenticated user can perform time-based blind SQL injection to extract arbitrary database contents. Commit 75d45780728294ededa1e3f842f95295d3e7d144 contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, a user with the "Videos Moderator" permission can escalate privileges to perform full video management operations — including ownership transfer and deletion of any video — despite the permission being documented as only allowing video publicity changes (Active, Inactive, Unlisted). The root cause is that `Permissions::canModerateVideos()` is used as an authorization gate for full video editing in `videoAddNew.json.php`, while `videoDelete.json.php` only checks ownership, creating an asymmetric authorization boundary exploitable via a two-step ownership-transfer-then-delete chain. Commit 838e16818c793779406ecbf34ebaeba9830e33f8 contains a patch.

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.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the restreamer endpoint constructs a log file path by embedding user-controlled `users_id` and `liveTransmitionHistory_id` values from the JSON request body without any sanitization. This log file path is then concatenated directly into shell commands passed to `exec()`, allowing an authenticated user to achieve arbitrary command execution on the server via shell metacharacters such as `$()` or backticks. Commit 99b865413172045fef6a98b5e9bfc7b24da11678 contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `ImageGallery::saveFile()` method validates uploaded file content using `finfo` MIME type detection but derives the saved filename extension from the user-supplied original filename without an allowlist check. An attacker can upload a polyglot file (valid JPEG magic bytes followed by PHP code) with a `.php` extension. The MIME check passes, but the file is saved as an executable `.php` file in a web-accessible directory, achieving Remote Code Execution. Commit 345a8d3ece0ad1e1b71a704c1579cbf885d8f3ae contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, an unauthenticated API endpoint (`APIName=locale`) concatenates user input into an `include` path with no canonicalization or whitelist. Path traversal is accepted, so arbitrary PHP files under the web root can be included. In our test this yielded confirmed file disclosure and code execution of existing PHP content (e.g., `view/about.php`), and it *can* escalate to RCE if an attacker can place or control a PHP file elsewhere in the tree. As of time of publication, no patched versions are available.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the API plugin exposes a `decryptString` action without any authentication. Anyone can submit ciphertext and receive plaintext. Ciphertext is issued publicly (e.g., `view/url2Embed.json.php`), so any user can recover protected tokens/metadata. Commit 3fdeecef37bb88967a02ccc9b9acc8da95de1c13 contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `objects/pluginImport.json.php` endpoint allows admin users to upload and install plugin ZIP files containing executable PHP code, but lacks any CSRF protection. Combined with the application explicitly setting `session.cookie_samesite = 'None'` for HTTPS connections, an unauthenticated attacker can craft a page that, when visited by an authenticated admin, silently uploads a malicious plugin containing a PHP webshell, achieving Remote Code Execution on the server. Commit d1bc1695edd9ad4468a48cea0df6cd943a2635f3 contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, an unauthenticated server-side request forgery vulnerability in `plugin/Live/test.php` allows any remote user to make the AVideo server send HTTP requests to arbitrary URLs. This can be used to probe localhost/internal services and, when reachable, access internal HTTP resources or cloud metadata endpoints. Commit 1e6cf03e93b5a5318204b010ea28440b0d9a5ab3 contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `objects/import.json.php` endpoint accepts a user-controlled `fileURI` POST parameter with only a regex check that the value ends in `.mp4`. Unlike `objects/listFiles.json.php`, which was hardened with a `realpath()` + directory prefix check to restrict paths to the `videos/` directory, `import.json.php` performs no directory restriction. This allows an authenticated user with upload permission to: (1) steal any other user's private video files by importing them into their own account, (2) read `.txt`/`.html`/`.htm` files adjacent to any `.mp4` file on the filesystem, and (3) delete `.mp4` and adjacent text files if writable by the web server process. Commit e110ff542acdd7e3b81bdd02b8402b9f6a61ad78 contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, AVideo's `_session_start()` function accepts arbitrary session IDs via the `PHPSESSID` GET parameter and sets them as the active PHP session. A session regeneration bypass exists for specific blacklisted endpoints when the request originates from the same domain. Combined with the explicitly disabled session regeneration in `User::login()`, this allows a classic session fixation attack where an attacker can fix a victim's session ID before authentication and then hijack the authenticated session. Commit 5647a94d79bf69a972a86653fe02144079948785 contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `createKeys()` function in the LoginControl plugin's PGP 2FA system generates 512-bit RSA keys, which have been publicly factorable since 1999. An attacker who obtains a target user's public key can factor the 512-bit RSA modulus on commodity hardware in hours, derive the complete private key, and decrypt any PGP 2FA challenge issued by the system — completely bypassing the second authentication factor. Additionally, the `generateKeys.json.php` and `encryptMessage.json.php` endpoints lack any authentication checks, exposing CPU-intensive key generation to anonymous users. Commit 00d979d87f8182095c8150609153a43f834e351e contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the RTMP `on_publish` callback at `plugin/Live/on_publish.php` is accessible without authentication. The `$_POST['name']` parameter (stream key) is interpolated directly into SQL queries in two locations — `LiveTransmitionHistory::getLatest()` and `LiveTransmition::keyExists()` — without parameterized binding or escaping. An unauthenticated attacker can exploit time-based blind SQL injection to extract all database contents including user password hashes, email addresses, and other sensitive data. Commit af59eade82de645b20183cc3d74467a7eac76549 contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `aVideoEncoderChunk.json.php` endpoint is a completely standalone PHP script with no authentication, no framework includes, and no resource limits. An unauthenticated remote attacker can send arbitrary POST data which is written to persistent temp files in `/tmp/` with no size cap, no rate limiting, and no cleanup mechanism. This allows trivial disk space exhaustion leading to denial of service of the entire server. Commit 33d1bae6c731ef1682fcdc47b428313be073a5d1 contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `sanitizeFFmpegCommand()` function in `plugin/API/standAlone/functions.php` is designed to prevent OS command injection in ffmpeg commands by stripping dangerous shell metacharacters (`&&`, `;`, `|`, `` ` ``, `<`, `>`). However, it fails to strip `$()` (bash command substitution syntax). Since the sanitized command is executed inside a double-quoted `sh -c` context in `execAsync()`, an attacker who can craft a valid encrypted payload can achieve arbitrary command execution on the standalone encoder server. Commit 25c8ab90269e3a01fb4cf205b40a373487f022e1 contains a patch.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `isSSRFSafeURL()` function in AVideo can be bypassed using IPv4-mapped IPv6 addresses (`::ffff:x.x.x.x`). The unauthenticated `plugin/LiveLinks/proxy.php` endpoint uses this function to validate URLs before fetching them with curl, but the IPv4-mapped IPv6 prefix passes all checks, allowing an attacker to access cloud metadata services, internal networks, and localhost services. Commit 75ce8a579a58c9d4c7aafe453fbced002cb8f373 contains a patch.
