GHSA-f3cw-hg6r-chfv: Craft CMS vulnerable to Potential Remote Code Execution via missing path normalization & Twig SSTI

### Summary Missing `normalizePath` in the function `FileHelper::absolutePath` could lead to Remote Code Execution on the server via twig SSTI. `(Post-authentication, ALLOW_ADMIN_CHANGES=true)` ### Details Note: This is a sequel to [CVE-2023-40035](https://github.com/craftcms/cms/security/advisories/GHSA-44wr-rmwq-3phw) In [`src/helpers/FileHelper.php#L106-L137`](https://github.com/craftcms/cms/blob/5e56c6d168524ed02f0620c9bc1c9750f5b94e3b/src/helpers/FileHelper.php#L106-L137), the function `absolutePath` returned `$from . $ds . $to` without path normalization: ```php /** * Returns an absolute path based on a source location or the current working directory. * * @param string $to The target path. * @param string|null $from The source location. Defaults to the current working directory. * @param string $ds the directory separator to be used in the normalized result.

GHSA-cw6g-qmjq-6w2w: Craft CMS Arbitrary System File Read

### Summary By abusing the mail notification template it is possible to read arbitrary operating system files. ### Details The [dataUrl](https://craftcms.com/docs/3.x/dev/functions.html#dataurl) function can be exploited if an attacker has write permissions on system notification templates. This function accepts an absolute file path, reads the file's content, and converts it into a Base64-encoded string. By embedding this function within a system notification template, the attacker can exfiltrate the Base64-encoded file content through a triggered system email notification. Once the email is received, the Base64 payload can be decoded, allowing the attacker to read arbitrary files on the server. Requirements: * write permissions to system notification templates * ability to trigger a corresponding system email ### PoC 1) Modify a template to contain the following twig template string: ```twig {{ dataUrl('/var/www/web/.env') }} ``` 2) Trigger the corresponding notification email (e...

GHSA-jrh5-vhr9-qh7q: Local File System Validation Bypass Leading to File Overwrite, Sensitive File Access, and Potential Code Execution

### Summary A vulnerability in CraftCMS allows an attacker to bypass local file system validation by utilizing a double `file://` scheme (e.g., `file://file:////`). This enables the attacker to specify sensitive folders as the file system, leading to potential file overwriting through malicious uploads, unauthorized access to sensitive files, and, under certain conditions, remote code execution (RCE) via Server-Side Template Injection (SSTI) payloads. Note that this will only work if you have an authenticated administrator account with [allowAdminChanges enabled](https://craftcms.com/docs/5.x/reference/config/general.html#allowadminchanges). https://craftcms.com/knowledge-base/securing-craft#set-allowAdminChanges-to-false-in-production ### Details The issue lies in line 57 of `cms/src/helpers/FileHelper.php`, it only removes `file://` on the most left. It is trivial to bypass this sanitization by adding 2 `file://`, e.g. `file://file:////`. ```php public static function normaliz...

GHSA-jrvm-mcxc-mf6m: dom-iterator code execution vulnerability

All versions of the package dom-iterator are vulnerable to Arbitrary Code Execution due to use of the Function constructor without complete input sanitization. Function generates a new function body and thus care must be given to ensure that the inputs to Function are not attacker-controlled. The risks involved are similar to that of allowing attacker-controlled input to reach eval.
