Detailsinfo

A vulnerability was found in WWBN AVideo-Encoder up to 6.x and classified as critical. This issue affects some unknown functionality. The manipulation of the argument base64Url with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

AVideo is a video-sharing Platform software. Prior to version 7.0, an unauthenticated attacker can execute arbitrary OS commands on the server by injecting shell command substitution into the base64Url GET parameter. This can lead to full server compromise, data exfiltration (e.g., configuration secrets, internal keys, credentials), and service disruption. This issue has been patched in version 7.0.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-29058 since 03/03/2026. The exploitation is known to be easy. The attack may be initiated remotely.
