Conversation
📝 WalkthroughWalkthroughTheme imports now reject shortcode-bearing stored headers and package files that automated review cannot process or that use non-portable names. Storage no longer strips shortcodes. Live-version processing escapes theme-name delimiters, with expanded PHPUnit coverage. ChangesTheme Upload Validation and Header Storage
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to Uploads can commit unreviewed or non-portable files despite passing validation, so this should be fixed before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Line 1532: Update the header title sanitization in the theme upload flow
around get('Name') so all shortcode-shaped input is neutralized before storage,
including unregistered tags that may be registered later; replace
strip_shortcodes() with the project’s all-shortcode sanitizer and add a
regression test covering a tag registered after storage.

setup; rely on the uninitialized initial state handled by
`create_or_update_theme_post()` for new submissions, preserving the declared
`WP_Post` type.

Follow-up to [15147], which took the same approach for `Description:`. `strip_shortcodes()` is a single pass, and a single pass can leave a shortcode in place: it unwraps an escaped `[[tag]]` into a live `[tag]`, and removing one shortcode can splice the remaining text into another, which is what `[gal[caption]lery ids="1"]` does. So the headers are refused at upload, where the author can be told, rather than edited into shape. `Theme URI` and `Author URI` come back out: `WP_Theme::get()` returns them through `esc_url_raw()`, which percent-encodes the delimiters, so those two cannot carry the syntax in the first place and the strip on them was a no-op. A test pins that, so they come back if it ever stops being true. The name has the second writer the description has -- `wporg_themes_approve_version()` re-reads `style.css` from SVN when a version goes live, without passing the upload's check -- so its delimiters are encoded there alongside the description's. That also covers names stored before this change. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NQJEFQckmb3KJiccmFUjPM

Follow-up to [15147], which handled
Description:this way. TheTheme Name:andAuthor:headers reachpost_titleand the_authorpost meta through the same writers, so they are handled the same way: refused atupload rather than edited into shape.
strip_shortcodes(), which this PR used to do, is a single pass, and a single pass can leave a shortcode in place:[[tag]]into a live[tag]—strip_shortcode_tag()returnssubstr( $match, 1, -1 )for that syntax by design.
[gal[caption]lery ids="1"]carries noshortcode until the inner
[caption]is taken out, at which point the remainder joins into a live[gallery ids="1"].Matching a shortcode has neither failing, and the uploader is told rather than having their header quietly rewritten.
Theme URIandAuthor URIcome back out of scope.WP_Theme::get()returns them throughesc_url_raw(), whichpercent-encodes the delimiters, so those two cannot carry the syntax in the first place and the strip on them was a
no-op.
test_uri_headers_are_inert_before_the_check()pins that, so they come back if it ever stops being true.The name has the second writer the description has —
wporg_themes_approve_version()re-readsstyle.cssfrom SVNwhen a version goes live, and a commit reaches it without passing the upload's check — so its delimiters are encoded
there alongside the description's. That also covers names stored before this change.
Bracketed prose is unaffected:
[developers]is not a registered shortcode, so nothing matches it.Testing steps
style.csshasTheme Name: Fixture [caption width="1" caption="x"]y[/caption] Theme. Theupload is refused with a message pointing at the
Theme Name:line. Try[[caption …]y[/caption]]and[gal[caption]lery ids="1"]too, and the same three inAuthor:; all are refused.A theme for [developers]. It is accepted, and the name reads as written.style.cssto SVN renaming a listed theme to a name carrying a shortcode, then take the version live.The stored title shows the brackets as text rather than running them.
