Description

Versions of csv-parse prior to 4.4.6 are vulnerable to Regular Expression Denial of Service. The __isInt() function contains a malformed regular expression that processes large specially-crafted input very slowly, leading to a Denial of Service. This is triggered when using the cast option.

Recommendation

Upgrade to version 4.4.6 or later.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for csv-parse, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update csv-parse to 4.4.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2019-17592 is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
