Homebrew casks can quit an app by a * wildcard bundle ID (uninstall quit: "com.elgato.WaveLink*"). The Homebrew ingester passed that ID straight to quit_application, whose osascript -e 'application id "…" is running' check fails with Can't get application id "com.elgato.WaveLink*". (-1728). The helper then returned early, and the app was never quit before rm -rf removed its bundle.

This PR adds a quit_matching_applications helper, emitted only for wildcard IDs, that mirrors Homebrew's expand_bundle_id:

• It lists running bundle IDs through NSWorkspace.runningApplications (JXA), inside the console user's session. When the script runs as root it uses launchctl asuser + sudo -u, the same way relaunch_application does.
• It matches IDs with an escaped regex that is anchored and case-insensitive. Only * is a wildcard.
• It only quits IDs made of [A-Za-z0-9._-]. A running app reports its own bundle ID, and quit_application runs it inside an AppleScript string as root.
• It quits each match once through the existing quit_application.
• If the listing itself fails, it prints "Failed to list running applications" and skips the quit, so a failure doesn't read as "no match".

quit_application is unchanged, so no other FMA's uninstall_script_ref changes, and the frozen copies in inputs/homebrew/scripts/ need no update.

Affected outputs (only the uninstall script changes):

• balenaEtcher (io.balena.etcher.*)
• Default Folder X (com.stclairsoft.DefaultFolderX*): the app is frozen (Update Fleet-maintained apps #54285), so the ingester won't rewrite this output. The uninstall script and its ref were edited by hand on top of main's 6.3.1 entry. The version, URL, sha256, install script, and DefaultFolderX5 queries stay as they are on main (the bundle ID fix is in Fix Default Folder X macOS FMA bundle identifier #54199).
• Elgato Wave Link (com.elgato.WaveLink*)
• VyprVPN (com.goldenfrog.VyprVPN*)

Default Folder X is the only frozen app with a wildcard quit ID. No custom input script uses one.

Note: the balenaEtcher cask's pattern requires the trailing dot, so it matches helper IDs like io.balena.etcher.helper but not the main app io.balena.etcher. That matches Homebrew's behavior.

Checklist for submitter

• Changes file added for user-visible changes in changes/, orbit/changes/ or ee/fleetd-chrome/changes.
  See Changes files for more information.

• Input data is properly validated, SELECT * is avoided, SQL injection is prevented (using placeholders for values in statements), JS inline code is prevented especially for url redirects, and untrusted data interpolated into shell scripts/commands is validated against shell metacharacters.
  The cask-controlled pattern is single-quoted with shellSingleQuote, and inside the helper it is only piped to sed as data. The running apps' bundle IDs are untrusted: a console user can launch an app whose ID matches the wildcard and contains AppleScript (for example " is running or (do shell script "…") …), which quit_application would run as root. The helper only passes IDs made of [A-Za-z0-9._-] to quit_application.

• Timeouts are implemented and retries are limited to avoid infinite loops
  Each match goes through quit_application's existing 10-second timeout.

Testing

• Added/updated automated tests

  • TestUninstallScriptExpandsQuitWildcard: wildcard IDs emit quit_matching_applications, and non-wildcard-only casks don't pick up the helper.
  • TestQuitMatchingApplicationsRunsMatches: runs the generated script in bash with osascript/stat/pgrep stubbed. It covers dedupe, case-insensitive matches, anchoring (x.com.elgato.WaveLink isn't matched), escaped regex metacharacters, a matching ID that carries AppleScript, no match, no GUI user, and a failed listing. Removing the dedupe, nocasematch, the escaping, the anchoring, or the bundle ID check each makes it fail. It passes with macOS /bin/bash 3.2 + BSD sed and with bash 5.3 + GNU sed.

• QA'd all new/changed functionality manually
  Ran a generated script as a non-root console user on macOS against a running Calculator with COM.apple.calcul*: it matched com.apple.calculator case-insensitively and quit it, and a non-matching pattern printed "No running application matches". A locally built app whose bundle ID matched the pattern and carried a do shell script payload ran that payload through the helper before the bundle ID check, and is skipped after it. The root path (launchctl asuser) was QA'd on a host: run as root with Calculator open, the helper printed EUID=0 and quit Calculator.

Summary by CodeRabbit

• Bug Fixes
  • Uninstalling balenaEtcher, Default Folder X, Elgato Wave Link, or VyprVPN now closes all running app instances with matching bundle IDs, including variant IDs.
  • The app-closing step is skipped if no regular user is logged in or running apps cannot be listed. If no matching apps are running, the uninstall reports this and continues.
  • Other removal steps remain unchanged.

Walkthrough

Wildcard uninstall directives now match running application bundle IDs and attempt to quit each match. Exact bundle ID directives continue to use quit_application. The helper skips matching when no non-root GUI user is logged in or when application listing fails. Four macOS uninstall references now use wildcard matching, and tests cover generated scripts and helper behavior.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to ec5cd

In environments that export Bash’s errexit option, affected app uninstalls can stop early. The fix is localized; address it before relying on those uninstalls.

Security Architecture Review

Security architecture risk: 🔵 Low · up to ec5cd

The change limits application selection with anchored matching and validates identifiers before passing them to AppleScript. Existing removal behavior remains unchanged. Risk is low, with uncertainty around real macOS root-session execution and applications changing while uninstall runs.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — Exposure expands from an ineffective literal wildcard lookup to matching application identities in the enumerated GUI session. Scope depends on the cask pattern: a broad pattern could select many valid IDs. Application identity is based on the reported bundle ID, not verified publisher provenance. The existing quit sink executes with the script caller's identity, which can be root.

Security Findings and Attack Paths

• inferred — The reviewed wildcard path does not establish an AppleScript injection route from a malicious application's reported identifier: quote and scripting characters are rejected before the privileged sink. The supplied test includes an AppleScript-bearing identifier and asserts that it is excluded, although the test stubs actual AppleScript execution.

Trust Boundaries and Controls

• observed — Cask patterns enter generated shell statements through single-argument shell quoting. Root enumeration explicitly enters the console user's session and drops command identity through sudo; returned application IDs cross back into the caller's quit operation only after validation. Real root-session execution is not covered by the supplied test, which skips when running as root.

Resilience and Maintainability Implications

• inferred — The transition is sequential but not atomic. Exact duplicate IDs are removed within one snapshot, but overlapping directives can repeat attempts, and applications or console sessions can change before quitting. There is no new identity reservation, rollback or interruption recovery. These limitations mean the helper improves quit selection without proving that every removed application has stopped.

Make the nocasematch snapshot safe under errexit.

If Orbit starts with SHELLOPTS containing errexit, its installer runner passes that environment to the generated Bash script. With nocasematch unset, shopt -p nocasematch returns 1, so this assignment can exit the script before it quits matching apps or runs later uninstall statements. The new test uses bash -c without -e, so it does not cover this case.
