CVE-2024-8242 | MStore API – Create Native Android & iOS Apps On The Cloud <= 4.15.3 - Authenticated (Subscriber+) Limited Arbitrary File Upload

The MStore API – Create Native Android & iOS Apps On The Cloud plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the update_user_profile() function in all versions up to, and including, 4.15.3. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload arbitrary files (not including PHP files) on the affected site's server which may make remote code execution possible. This can be paired with a registration endpoint for unauthenticated users to exploit the issue.

4.3 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/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:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.

Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
