Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

pheditor before 2.0.7 lets a user with the terminal permission run arbitrary commands as the web server user. The terminal allowlist only checks command prefixes, so allowed programs such as find, git, php and tar can run other programs through their options. Upgrade to pheditor 2.0.7.

Written 3 Nov 2026.
