Harden phpcs utilities: escape filenames instead of only spaces - #1532
Conversation
WalkthroughThe PHPCS pull-request and push utilities now check for an empty changed-file list before processing paths. Both scripts retain the existing no-files message and successful exit. Each changed-file path now uses Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The helpers now improve shell safety, but Git-encoded filenames may still cause PHPCS to skip changed files, and the push helper has an unresolved formatting/end-of-file check issue. These bounded correctness and readiness problems should be addressed before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

.github/workflows/utilities/phpcs-pr lines 26-27 and
.github/workflows/utilities/phpcs-push lines 26-27, so PHPCS treats filenames
beginning with hyphens as paths rather than options; update the shared $files
mapping in each utility and preserve the existing shell escaping.

The phpcs-pr/phpcs-push helpers passed changed filenames straight into the PHPCS shell command with only spaces escaped. A crafted filename could inject shell metacharacters, and — because PHPCS parses a leading-dash argument as an option — a name like `--bootstrap=...` could load arbitrary PHP. Escape each path with escapeshellarg() and prefix it with `./` so it can never be interpreted as an option. Also fixes two pre-existing style nits in phpcs-push (double space after a comma, extra trailing blank line) that surface now the file is linted.

Git diff --name-only -z pathname quoting documentation core.quotePath C-style quoted filenames
💡 Result:
In Git, commands that output pathnames—such as git diff --name-only—default to quoting "unusual" characters in filenames [1][2]. This behavior is controlled by the configuration variable core.quotePath [2][3]. When core.quotePath is enabled (the default), Git inspects pathnames for characters deemed "unusual," which include control characters (such as TAB, LF, and backslash) and non-ASCII bytes (values greater than 0x80) [2][3][4]. If any such character is detected, the entire pathname is enclosed in double quotes, and the special characters are escaped using C-style backslash notation (e.g., \t, \n, \, or octal sequences like \302\265) [2][3]. Notably, a simple space is not considered an "unusual" character and does not trigger this quoting behavior [2][4]. If core.quotePath is set to false, Git stops quoting non-ASCII bytes (values > 0x80) and outputs them verbatim [2][3]. However, double quotes, backslashes, and control characters will still be escaped regardless of this setting [2][3]. To bypass this quoting mechanism entirely and receive filenames verbatim regardless of their content, you can use the -z option [1][5][2]. When -z is used with commands like git diff --name-only, pathnames are output exactly as they are, and each entry is terminated by a NUL byte rather than a newline [1][5][2]. Configuration: You can disable the automatic quoting of non-ASCII characters by running: git config --global core.quotePath false Top results: [1] https://git-scm.com/docs/git-diff [2] https://git-scm.com/docs/git-config/2.20.0 [3] https://linux.die.net/man/1/git-config [4] https://public-inbox.org/git/201001011844.23571.agruen@suse.de/T/

Decode Git pathnames before shell escaping in both utilities.
git diff --name-only and git show --name-only can emit C-quoted pathnames. escapeshellarg() then passes the encoded text to PHPCS, so PHPCS may skip the changed file. Use -z, split $fileList on "\0", and escape each raw pathname in both utilities.

What
The
phpcs-pr/phpcs-pushhelpers in.github/workflows/utilities/built the PHPCS command by concatenating changed filenames with only spaces backslash-escaped. Any other shell metacharacter in a crafted filename could therefore be interpreted by the shell (shell_exec).Change
Pass each path through
escapeshellarg()when assembling the command, and drop the now-redundant manual space-escaping loop. The existing empty-diff early-exit is unchanged.These helpers are copied into Storm and many plugins; this fixes the canonical source. (The same change has been synced to Storm and the Winter plugins that carry a copy.)
