Description

The Simple File List plugin for WordPress is vulnerable to unauthorized file operations due to a missing authorization check on the 'frontmanage' shortcode attribute in all versions up to, and including, 6.3.7. This makes it possible for authenticated attackers, with contributor-level access and above, to perform arbitrary file operations including deletion, move, folder creation, and download. An attacker can create a draft post containing the 'eeSFL' shortcode, render it via the post preview endpoint to harvest the nonce needed to authorize the operations, and then submit file operation requests that bypass the intended authorization checks in includes/ee-list-ops-bar-process.php.

Base score Version Severity Vector
6.5 3.1
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N 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:N)
Service keeps running; no real outage angle.
