{"id":"DEBIAN-CVE-2026-9496","details":"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.","modified":"2026-09-12T17:00:08.244254400Z","published":"2026-05-26T07:16:19.410Z","upstream":["CVE-2026-9496"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-9496"}],"affected":[{"package":{"name":"npm","ecosystem":"Debian:12","purl":"pkg:deb/debian/npm?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11.12.1~ds1-1","11.12.1~ds1-2","11.12.1~ds1-3","11.12.1~ds1-4","11.13.0~ds1-1","11.16.0+ds2-1","11.16.0+ds2-2","11.16.0+ds2-3","11.16.0+ds2-4","11.19.0+ds1-1","11.19.0+ds1-2","11.19.0-1","12.0.2+ds1-1","12.0.2+ds1-2","9.2.0~ds1-1","9.2.0~ds1-2","9.2.0~ds1-3","9.2.0~ds1-4","9.2.0~ds2-1","9.2.0~ds2-2","9.2.0~ds3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-9496.json"}},{"package":{"name":"npm","ecosystem":"Debian:13","purl":"pkg:deb/debian/npm?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11.12.1~ds1-1","11.12.1~ds1-2","11.12.1~ds1-3","11.12.1~ds1-4","11.13.0~ds1-1","11.16.0+ds2-1","11.16.0+ds2-2","11.16.0+ds2-3","11.16.0+ds2-4","11.19.0+ds1-1","11.19.0+ds1-2","11.19.0-1","12.0.2+ds1-1","12.0.2+ds1-2","9.2.0~ds1-3","9.2.0~ds1-4","9.2.0~ds2-1","9.2.0~ds2-2","9.2.0~ds3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-9496.json"}},{"package":{"name":"npm","ecosystem":"Debian:14","purl":"pkg:deb/debian/npm?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"12.0.2+ds1-1"}]}],"versions":["11.12.1~ds1-1","11.12.1~ds1-2","11.12.1~ds1-3","11.12.1~ds1-4","11.13.0~ds1-1","11.16.0+ds2-1","11.16.0+ds2-2","11.16.0+ds2-3","11.16.0+ds2-4","11.19.0+ds1-1","11.19.0+ds1-2","11.19.0-1","9.2.0~ds1-3","9.2.0~ds1-4","9.2.0~ds2-1","9.2.0~ds2-2","9.2.0~ds3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-9496.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
