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

LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.1, 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 wit...

CVE-2026-33285

LiquidJS memoryLimit bypass vulnerability (CVE-2026-33285) arises from reverse-range evaluation (low > high) producing a negative count in ctx.memoryLimit.use(high - low + 1) and a non-negative check in Limiter.use(), allowing memory budget manipulation. This enables an attacker to allocate la...
