CVE-2023-2361Network attack vector

Stored XSS via unsanitized link attributes

Published Apr 28, 2023 · Updated Jan 30, 2025

Stored XSS in Pimcore before 10.5.21 allows remote authenticated users to run script in pages viewed by other users. The Document Link editable accepts event-handler attributes and inserts unsanitized Parameters, Anchor, and other attribute values into generated anchor markup. An authenticated editor must save crafted link data; viewing the resulting document executes script in the viewer's origin, enabling page modification and access to browser-held data.
