CVE-2026-33293 | AVideo Affected by Arbitrary File Deletion via Path Traversal in CloneSite deleteDump Parameter

Exp

WWBN AVideo is an open source video platform. Prior to version 26.0, the `deleteDump` parameter in `plugin/CloneSite/cloneServer.json.php` is passed directly to `unlink()` without any path sanitization. An attacker with valid clone credentials can use path traversal sequences (e.g., `../../`) to delete arbitrary files on the server, including critical application files such as `configuration.php`, causing complete denial of service or enabling further attacks by removing security-critical files. Version 26.0 fixes the issue.

Base score Version Severity Vector Exploitability Impact Score source
8.1 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
