CVE-2026-33285: LiquidJS: memoryLimit Bypass through Negative Range Values Leads to Process Crash

March 25, 2026

LiquidJS’s memoryLimit security mechanism can be completely bypassed by using reverse range expressions (e.g., (100000000..1)), allowing an attacker to allocate unlimited memory. Combined with a string flattening operation (e.g., replace filter), this causes a V8 Fatal error that crashes the Node.js process, resulting in complete denial of service from a single HTTP request.
