CVE-2025-3597 | Firelight Lightbox < 2.3.15 - Contributor+ Stored XSS

Exp

The Firelight Lightbox WordPress plugin before 2.3.15 does not prevent users with post writing capabilities from executing arbitrary Javascript when the jQuery Metadata library is enabled. While this feature is meant to only be available to Pro version users, it can be activated in the free version too, making it theoretically exploitable there as well.

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:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
