Cross-site Scripting vulnerability in Mautic's tracking pixel functionality

Description

Impact

Mautic allows you to track open rates by using tracking pixels.
The tracking information is stored together with extra metadata of the tracking request.

The output isn't sufficiently filtered when showing the metadata of the tracking information, which may lead to a vulnerable situation.

Patches

Please upgrade to 4.3.0

Workarounds

None.

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:N)
No account or special rights needed—anonymous or random user is enough.
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:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
