CVE-2026-33285: CWE-20: Improper Input Validation in harttle liquidjs
CVE-2026-33285 is a high-severity vulnerability in the LiquidJS template engine prior to version 10. 25. 1. The issue involves improper input validation allowing the memoryLimit security mechanism to be bypassed using reverse range expressions. This can lead to unlimited memory allocation and a subsequent V8 fatal error that crashes the Node. js process, causing a denial of service. The vulnerability is patched in LiquidJS version 10. 25. 1.
AI Analysis
Technical Summary
LiquidJS versions before 10.25.1 contain an input validation flaw where reverse range expressions (e.g., (100000000..1)) bypass the memoryLimit control. When combined with string flattening operations like the replace filter, this triggers a V8 fatal error that crashes the Node.js runtime, resulting in a denial of service condition. The vulnerability is tracked as CVE-2026-33285 with a CVSS 3.1 base score of 7.5 (high severity). The issue is fixed in version 10.25.1 of LiquidJS.
Potential Impact
An attacker can cause a denial of service by sending a crafted request that exploits the bypass of the memoryLimit mechanism, leading to unlimited memory allocation and a fatal crash of the Node.js process running LiquidJS. This results in complete service disruption from a single HTTP request. There is no indication of confidentiality or integrity impact.
Mitigation Recommendations
Upgrade LiquidJS to version 10.25.1 or later, where this vulnerability is patched. No other mitigations are indicated or necessary once the update is applied.
