An issue was discovered in Sylius products. Missing input sanitization in sylius/sylius 1.0.x through 1.0.18, 1.1.x through 1.1.17, 1.2.x through 1.2.16, 1.3.x through 1.3.11, and 1.4.x through 1.4.3 and sylius/grid 1.0.x through 1.0.18, 1.1.x through 1.1.18, 1.2.x through 1.2.17, 1.3.x through 1.3.12, 1.4.x through 1.4.4, and 1.5.0 allows an attacker (an admin in the sylius/sylius case) to perform XSS by injecting malicious code into a field displayed in a grid with the "string" field type. The contents are an object, with malicious code returned by the __toString() method of that object.

4.8 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/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: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:N)
Service keeps running; no real outage angle.

Exploitation needs some favorable conditions, but not exceptional ones.
Authentication (AU:S)
A single authentication is required.
Confidentiality impact (C:N)
No confidentiality impact.
Integrity impact (I:P)
Partial integrity impact.
