An attacker can:\n- Send a large number of bracket notation parameters (e.g., `a[]=1\u0026a[]=2\u0026...`) in a single HTTP request\n- Exhaust server memory\n- Cause application unavailability\n- Execute the attack without authentication\n\n### References\n\n- [Snyk Advisory](https://security.snyk.io/vuln/SNYK-JS-QS-14724253)\n- [NVD Entry](https://nvd.nist.gov/vuln/detail/CVE-2025-15284)\n- [GitHub Security Advisory](https://github.com/ljharb/qs/security/advisories/GHSA-6rw7-vpxm-498p)\n\n## Current State\n\nIn `contentstack@3.17.1`:\n\"dependencies\": {\n  \"qs\": \"^6.11.1\"\n}\nLockfile shows: `qs@6.11.2` (still vulnerable)\n\n## Question\n\nI noticed that my package-lock.json shows `contentstack@3.17.1` with `qs@6.11.2`. Does version **3.22.0 or later** include the fix for this vulnerability (using `qs@6.14.1`)?\n\nIf so, I can simply upgrade. If not, could you please update the `qs` dependency to `^6.14.1` in an upcoming release?\n\n## Environment\n\n- **Package**: contentstack@3.17.1\n- **Vulnerable dependency**: qs@6.11.2\n- **Package manager**: npm\n\n## Additional Information\n\nThis vulnerability is actively being scanned by security tools (Snyk) and is blocking security compliance for applications using Contentstack. Guidance on upgrading or a patch release would be greatly appreciated.\n\nThank you for your attention to this security issue!","author":{"url":"https://github.com/jalinsub","@type":"Person","name":"jalinsub"},"datePublished":"2026-01-06T02:04:55.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/372/contentstack-javascript/issues/372"}
