Description OSIDB Bzimport 2026-05-26 07:01:14 UTC 
Versions of the package pacote from 11.2.7 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.
