{"id":"UBUNTU-CVE-2026-59856","details":"Vim is an open source, command line text editor. Prior to 9.2.0736, the PHP omni-completion script in runtime/autoload/phpcomplete.vim interpolates a class or trait name, taken from the contents of the edited buffer, into a search() pattern that is run via win_execute() without escaping. A name containing a single quote can terminate the search() string argument early, and because the bar is honored as an Ex command separator, the remainder of the name is run as Ex commands; via the :! command this allows arbitrary operating-system command execution when a victim opens a crafted PHP file and invokes omni-completion. This issue is fixed in version 9.2.0736.","modified":"2026-07-14T23:30:25.665783637Z","published":"2026-07-10T00:00:00Z","related":["USN-8541-1"],"upstream":["CVE-2026-59856"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-59856"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-59856"},{"type":"REPORT","url":"https://github.com/vim/vim/security/advisories/GHSA-fh26-8f79-wj97"},{"type":"REPORT","url":"https://github.com/vim/vim/commit/43afc581a37a35762dd0ef292f038b9dc5680a24"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8541-1"}],"affected":[{"package":{"name":"vim","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/vim?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:8.2.3995-1ubuntu2.34"}]}],"versions":["2:8.2.2434-3ubuntu3","2:8.2.2434-3ubuntu4","2:8.2.3565-1ubuntu1","2:8.2.3565-1ubuntu2","2:8.2.3565-1ubuntu3","2:8.2.3565-1ubuntu5","2:8.2.3995-1ubuntu1","2:8.2.3995-1ubuntu2","2:8.2.3995-1ubuntu2.1","2:8.2.3995-1ubuntu2.3","2:8.2.3995-1ubuntu2.4","2:8.2.3995-1ubuntu2.5","2:8.2.3995-1ubuntu2.7","2:8.2.3995-1ubuntu2.8","2:8.2.3995-1ubuntu2.9","2:8.2.3995-1ubuntu2.10","2:8.2.3995-1ubuntu2.11","2:8.2.3995-1ubuntu2.12","2:8.2.3995-1ubuntu2.13","2:8.2.3995-1ubuntu2.15","2:8.2.3995-1ubuntu2.16","2:8.2.3995-1ubuntu2.17","2:8.2.3995-1ubuntu2.18","2:8.2.3995-1ubuntu2.19","2:8.2.3995-1ubuntu2.20","2:8.2.3995-1ubuntu2.21","2:8.2.3995-1ubuntu2.22","2:8.2.3995-1ubuntu2.23","2:8.2.3995-1ubuntu2.24","2:8.2.3995-1ubuntu2.26","2:8.2.3995-1ubuntu2.27","2:8.2.3995-1ubuntu2.28","2:8.2.3995-1ubuntu2.29","2:8.2.3995-1ubuntu2.30","2:8.2.3995-1ubuntu2.31","2:8.2.3995-1ubuntu2.32","2:8.2.3995-1ubuntu2.33"],"ecosystem_specific":{"availability":"No
