Denial of service in npm's pacote package (versions 11.2.7 and later) allows remote unauthenticated attackers to exhaust CPU by submitting a crafted spec.rawSpec value to the addGitSha function, where vulnerable regex and string-manipulation logic exhibits catastrophic backtracking. CVSS 4.0 scores this 7.7 (high availability impact, no integrity/confidentiality impact) and SSVC labels exploitation as POC with automatable=yes, though EPSS remains low at 0.04% (11th percentile). No active exploitation has been reported and no public exploit identified at time of analysis, but the bug is trivially triggerable wherever pacote parses untrusted package specs.
