CVE-2026-33750 (opens in a new tab)How to fix?
Upgrade org.webjars.npm:brace-expansion to version 1.1.13, 2.0.3, 3.0.2, 5.0.5 or higher.
Overview
org.webjars.npm:brace-expansion is a WebJar for brace-expansion.
Affected versions of this package are vulnerable to Infinite loop through the expand function when processing a brace pattern with a zero step value. An attacker can cause the process to hang and exhaust system memory by supplying specially crafted input, such as {1..2..0}. This can lead to significant resource consumption and denial of service.
Workaround
This vulnerability can be mitigated by sanitizing strings passed to expand to ensure a step value of 0 is not used.
