CVE-2022-0262Network attack vector

Stored script execution via media query name

Published Jan 18, 2022 · Updated Aug 2, 2024

Stored cross-site scripting in Pimcore before 10.2.7 allows remote attackers to execute script in a victim's browser via crafted media query names. The thumbnailUpdateAction handler accepted media query names containing HTML or quote characters, and the client rendered those names without validation, persisting attacker-controlled markup into pages. Exploitation requires a victim to open the affected Pimcore interface and interact with the stored content; script can read or modify page data within that browser session.
