CVE-2026-29058
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
