{"id":"DEBIAN-CVE-2026-67550","details":"re2 provides Node.js bindings for Google's RE2 regular expression engine. Prior to 1.25.2, re2 validates lastIndex against the UTF-8 byte length of a subject but uses it as a UTF-16 code-unit offset in exec, test, match, replace, and split, allowing an attacker-influenced lastIndex on a non-ASCII subject to trigger an out-of-bounds heap read and an uncatchable process crash, with limited heap information disclosure in some cases. This issue is fixed in 1.25.2.","modified":"2026-09-11T08:47:43.437516359Z","published":"2026-07-30T20:18:15.030Z","upstream":["CVE-2026-67550"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-67550"}],"affected":[{"package":{"name":"node-re2","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-re2?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.18.0+~cs2.13.8-1","1.19.2+~cs2.13.13-1","1.20.10+~cs2.13.13-1","1.20.12+~cs2.13.13-1","1.21.4+~cs2.13.13-1","1.21.4+~cs2.13.13-2","1.22.1+~cs1.3.5-1","1.23.3+~cs1.3.5-1","1.25.0+~cs1.6.0-1","1.25.0+~cs1.6.0-2","1.26.1+~cs1.7.0-1","1.26.1+~cs1.8.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-67550.json"}},{"package":{"name":"node-re2","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-re2?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.21.4+~cs2.13.13-2","1.22.1+~cs1.3.5-1","1.23.3+~cs1.3.5-1","1.25.0+~cs1.6.0-1","1.25.0+~cs1.6.0-2","1.26.1+~cs1.7.0-1","1.26.1+~cs1.8.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-67550.json"}},{"package":{"name":"node-re2","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-re2?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.26.1+~cs1.7.0-1"}]}],"versions":["1.21.4+~cs2.13.13-2","1.22.1+~cs1.3.5-1","1.23.3+~cs1.3.5-1","1.25.0+~cs1.6.0-1","1.25.0+~cs1.6.0-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-67550.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:H"}]}
