What is CVE-2026-55208?
CVE-2026-55208 is a high-severity SQL injection vulnerability in pimcore, published on 9 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Pimcore Studio Backend Bundle is the backend bundle for Pimcore Studio. Prior to 2025.4.6 and 2026.1.6, an authenticated user can extract the admin password hash and other database content through time-based blind SQL injection in the DateFilter column key parameter. The POST /pimcore-studio/api/website-settings endpoint and other listing endpoints accept a columnFilters array where the key field is interpolated directly into SQL with manual backtick wrapping, allowing a backtick character to break out of quoting and append arbitrary SQL such as SLEEP() and IF() subqueries. This issue is fixed in versions 2025.4.6 and 2026.1.6.
Weakness: CWE-89
