CVE-2026-127056 - PapaParse before 5.7.1 Quadratic-Time Parsing DoS via indexOf Scan
CVE ID :CVE-2026-127056
Published : Nov. 12, 2026, 12:39 p.m. | 20 minutes ago
Description :PapaParse before 5.7.1 contains an inefficient algorithmic complexity vulnerability that allows remote unauthenticated attackers to cause denial of service by submitting delimiter-free quoted CSV input to Papa.parse(). Attackers can supply a single-column quoted CSV with no delimiters, triggering repeated full-buffer indexOf scans per row that grow quadratically with input size, exhausting CPU and blocking the Node.js event loop or freezing a browser tab.
Severity: 8.7 | HIGH
