An issue was discovered in Bloomreach Experience Manager (brXM) 4.1.0 through 14.2.2. It allows remote attackers to execute arbitrary code because there is a mishandling of the capability for administrators to write and run Groovy scripts within the updater editor. An attacker must use an AST transforming annotation such as @Grab.

Exploit prediction

3.64% chance of exploitation in the next 30 days, higher than 89% of all scored CVEs (FIRST EPSS, 2026-11-08).
