WWBN AVideo versions up to and including 26.0 are affected by two high-severity flaws that can lead to remote code execution. CVE-2026-33482 is an OS command injection bug in sanitizeFFmpegCommand(), which strips some shell metacharacters but fails to remove bash command substitution using $(). Because the resulting ffmpeg command is later executed in a double-quoted sh -c context by execAsync(), an attacker able to craft a valid encrypted payload can run arbitrary commands on the standalone encoder server.
A separate issue, CVE-2026-33507, allows unauthenticated code execution through the plugin import workflow. The objects/pluginImport.json.php endpoint permits admin users to upload and install plugin ZIP archives containing executable PHP, but lacks CSRF protection; with session.cookie_samesite = 'None' on HTTPS connections, an attacker can trick a logged-in administrator into silently importing a malicious plugin and deploying a PHP webshell. Fixes were introduced in commits 25c8ab90269e3a01fb4cf205b40a373487f022e1 and d1bc1695edd9ad4468a48cea0df6cd943a2635f3.

4 events from the most recent confirmed update back to the earliest known activity.
A high-severity AVideo vulnerability was publicly disclosed showing that missing CSRF protection on objects/pluginImport.json.php could let an unauthenticated attacker induce an administrator to upload a malicious plugin and gain code execution. The issue affects versions up to and including 26.0.
A high-severity vulnerability in WWBN AVideo was publicly disclosed describing how incomplete sanitization in sanitizeFFmpegCommand() could allow arbitrary command execution on the standalone encoder server. The issue affects versions up to and including 26.0.
WWBN AVideo fixed a CSRF vulnerability affecting versions up to and including 26.0 in the plugin import endpoint, which could let an attacker trick a logged-in administrator into uploading a malicious plugin and achieve remote code execution. The patch was included in commit d1bc1695edd9ad4468a48cea0df6cd943a2635f3.
WWBN AVideo fixed an OS command injection vulnerability affecting versions up to and including 26.0, where sanitizeFFmpegCommand() failed to block $() shell substitution before execution in a sh -c context. The patch was introduced in commit 25c8ab90269e3a01fb4cf205b40a373487f022e1.

WWBN **AVideo** was found to contain multiple high-severity vulnerabilities that can let attackers seize control of deployments, hijack user sessions, and access internal network resources. On uninitialized instances running version **25.0 or earlier**, `install/checkConfiguration.php` could be abused without authentication to complete setup, create an administrator account, and write configuration files, enabling full application takeover under **CVE-2026-33038**. Separate insecure defaults in the official Docker deployment path, tracked as **CVE-2026-33037**, left new installations exposed to immediate administrative compromise because the admin password defaulted to **"password"** and database credentials defaulted to `avideo/avideo`, with no forced password change or effective hardening. AVideo also exposed users and infrastructure through web-facing flaws in session handling and URL fetching. Under **CVE-2026-33043**, `/objects/phpsessionid.json.php` disclosed active PHP session IDs to unauthenticated requests, and permissive CORS behavior could allow cross-origin session theft and account takeover. Two SSRF issues affected the unauthenticated `plugin/LiveLinks/proxy.php` endpoint: **CVE-2026-33039** allowed redirect-based bypass of URL safety checks in version **25.0 and earlier**, while **CVE-2026-33480** showed that `isSSRFSafeURL()` could also be bypassed with IPv4-mapped IPv6 addresses, extending exposure through version **26.0** and enabling access to localhost, RFC1918 networks, and cloud metadata services. WWBN issued fixes in **AVideo 26.0** for most of the disclosed flaws, with an additional patch published for the IPv6-based SSRF bypass.

A critical, **zero-click unauthenticated OS command injection** vulnerability was disclosed in the open-source video hosting/streaming platform **AVideo**, tracked as **CVE-2026-29058**. The flaw affects versions **prior to 7.0** (including **6.0**) and allows remote attackers to execute arbitrary operating system commands on the server without user interaction or prior privileges, creating a path to **full server compromise**, **data exfiltration** (e.g., configuration secrets, internal keys, credentials), and **service disruption**. The issue stems from `objects/getImage.php`, where attacker-controlled input in the `base64Url` GET parameter is Base64-decoded and incorporated into a double-quoted `ffmpeg` shell command without proper escaping/neutralization of shell metacharacters and command substitution (CWE-78). The vulnerability was reported by security researcher **Arkmarta**, and remediation is available by upgrading to **AVideo 7.0 or later**, which includes the official patch.

WWBN **AVideo** was found to contain multiple high-severity flaws in its `CloneSite` plugin that can be abused for destructive attacks and full server compromise. One issue, tracked as `CVE-2026-33293`, affects versions prior to **26.0** and allows arbitrary file deletion through path traversal in the `deleteDump` parameter of `plugin/CloneSite/cloneServer.json.php`. Because the value was passed directly to `unlink()` without sanitization, an attacker with valid clone credentials could use `../../` sequences to remove arbitrary files such as `configuration.php`, causing denial of service and potentially weakening other protections. A second issue, `CVE-2026-33478`, describes a broader attack chain in AVideo versions up to and including **26.0** that can lead to **unauthenticated remote code execution**. The `clones.json.php` endpoint exposed clone secret keys without authentication, which could then be used to trigger a full database dump via `cloneServer.json.php`; the dump reportedly included admin password hashes stored as **MD5**, enabling attackers to recover credentials and gain administrative access. From there, an OS command injection flaw in `cloneClient.json.php` involving `rsync` command construction could be used to execute arbitrary system commands. The vulnerabilities were mapped to `CWE-22`, `CWE-78`, and `CWE-284`, and fixes were released by WWBN, including a patch referenced in commit `c85d076375fab095a14170df7ddb27058134d38c`.
