# CVE-2026-9496

> 8.7 HIGH · 🧪 PoC

## Beschreibung

Versions of the package pacote from 11.2.7 and before 21.5.1 are vulnerable to Denial of Service (DoS) via the addGitSha function. An attacker can exploit this vulnerability by supplying a specially crafted spec.rawSpec value that triggers the function’s regex replacement and string-manipulation logic,  causing excessive CPU consumption and potentially stalling or crashing the process.
