**Endpoint**: `admin/config/system` **Submenu**: `Languages` **Parameter**: `Supported` **Application**: Grav v 1.7.48 --- ## Summary A Denial of Service (DoS) vulnerability was identified in the **"Languages"** submenu of the Grav **admin configuration panel** (`/admin/config/system`). Specifically, the `Supported` parameter fails to properly validate user input. If a malformed value is inserted—such as a single forward slash (`/`) or an XSS test string—it causes a fatal regular expression parsing error on the server. This leads to application-wide failure due to the use of the `preg_match()` function with an **improperly constructed regular expression**, resulting in the following error: `preg_match(): Unknown modifier 'o' File: /system/src/Grav/Common/Language/Language.php line 244` Once triggered, the site becomes completely unavailable to all users. --- ## Details - **Vulnerable Endpoint**: `POST /admin/config/system` - **Submenu**: `Languages` - **Paramet...

## **Summary** An **IDOR (Insecure Direct Object Reference)** vulnerability in the Grav CMS Admin Panel allows **low-privilege users to access sensitive information** from other accounts. Although direct account takeover is not possible, **admin email addresses and other metadata can be exposed**, increasing the risk of phishing, credential stuffing, and social engineering. --- ## **Details** * **Endpoint:** `/admin/accounts/users/{username}` * **Tested Version:** Grav Admin 1.7.48 * **Affected Accounts:** Authenticated users with **0 privileges** (non-privileged accounts) **Description:** Requesting another user’s account details (e.g., `/admin/accounts/users/admin`) as a low-privilege user returns an HTTP **403 Forbidden** response. However, sensitive information such as the **admin’s email address** is still present in the **response source**, specifically in the `<title>` tag. **system/src/Grav/Common/Flex/Types/Users/UserCollection.php** <img width="700" height="327" alt="Sc...

# Grav v1.7.49.5 / Admin v1.10.49.1 – User Enumeration & Email Disclosure ### Summary A **user enumeration and email disclosure vulnerability** exists in Grav **v1.7.49.5** with Admin plugin **v1.10.49.1**. The "Forgot Password" functionality at `/admin/forgot` leaks information about valid usernames and their associated email addresses through distinct server responses. This allows an attacker to enumerate users and disclose sensitive email addresses, which can be leveraged for targeted attacks such as password spraying, phishing, or social engineering. ### Details The issue resides in the [`taskForgot()`](https://github.com/getgrav/grav-plugin-admin/blob/6d673fc7c4f6962756f93ae651371e81f7f20924/classes/plugin/Controllers/Login/LoginController.php#L349) function, which handles the forgot password workflow. Relevant vulnerable logic: ```php if (null === $user || $user->state !== 'enabled' || !$to) { ... // Generic message for invalid/non-existing users $this->se...

## Summary Grav CMS is vulnerable to a Server-Side Template Injection (SSTI) that allows any authenticated user with editor permissions to execute arbitrary code on the remote server, bypassing the existing security sandbox. ## Details Grav CMS uses a custom sandbox to protect the powerful Twig methods such as `registerUndefinedFilterCallback()`. These methods are designed to prevent SSTI attacks by denying the execution of dangerous PHP functions (e.g., `exec()`, `passthru()`, `system()`, etc.) within Twig template directives. The current defense mechanism relies on a blacklist of prohibited functions (PHP, Twig), checked through the `isDangerousFunction()` method in the file `system/src/Grav/Common/Twig.php`: ```php $this->twig->registerUndefinedFilterCallback(function (string $name) use ($config) { $allowed = $config->get('system.twig.safe_filters'); if (is_array($allowed) && in_array($name, $allowed, true) && function_exists($name)) { return new TwigFilter($nam...

## Summary The `fonttools varLib` (or `python3 -m fontTools.varLib`) script has an arbitrary file write vulnerability that leads to remote code execution when a malicious .designspace file is processed. The vulnerability affects the `main()` code path of `fontTools.varLib`, used by the fonttools varLib CLI and any code that invokes `fontTools.varLib.main()`. The vulnerability exists due to unsanitised filename handling combined with content injection. Attackers can write files to arbitrary filesystem locations via path traversal sequences, and inject malicious code (like PHP) into the output files through XML injection in labelname elements. When these files are placed in web-accessible locations and executed, this achieves remote code execution without requiring any elevated privileges. Once RCE is obtained, attackers can further escalate privileges to compromise system files (like overwriting `/etc/passwd`). Overall this allows attackers to: - Write font files to arbitrary locatio...

### Summary A reflected Cross-Site Scripting (XSS) vulnerability exists in the Mediapool view where the request parameter `args[types]` is rendered into an info banner without HTML-escaping. This allows arbitrary JavaScript execution in the backend context when an authenticated user visits a crafted link while logged in. ### Details Control Flow: 1. `redaxo/src/addons/mediapool/pages/index.php` reads args via `rex_request('args', 'array')` and passes them through as `$argUrl` to `media.list.php`. 2. `redaxo/src/addons/mediapool/pages/media.list.php` injects `$argUrl['args']['types']` into an HTML string without escaping: ``` if (!empty($argUrl['args']['types'])) { echo rex_view::info(rex_i18n::msg('pool_file_filter') . ' <code>' . $argUrl['args']['types'] . '</code>'); } ``` ### PoC 1. Log into the REDAXO backend. 2. While authenticated, open a crafted URL like: `<host>/index.php?page=mediapool/media&args[types]="><img+src%3Dx+onerror%3Dalert%28document.domain%29>` 4. The inf...

### Impact Backend users with precise control over the contents of template closures can execute arbitrary PHP functions that do not have required parameters. ### Patches Update to Contao 4.13.57, 5.3.42 or 5.6.5 ### Workarounds Manually patch the `Contao\Template::once()` method. ### Resources https://contao.org/en/security-advisories/remote-code-execution-in-template-closures

A Remote Code Execution (RCE) vulnerability in the template management component in REDAXO CMS 5.20.0 allows remote authenticated administrators to execute arbitrary operating system commands by injecting PHP code into an active template. The payload is executed when visitors access frontend pages using the compromised template.

New research from CrowdStrike has revealed that DeepSeek's artificial intelligence (AI) reasoning model DeepSeek-R1 produces more security vulnerabilities in response to prompts that contain topics deemed politically sensitive by China. "We found that when DeepSeek-R1 receives prompts containing topics the Chinese Communist Party (CCP) likely considers politically sensitive, the likelihood of it

phpPgAdmin 7.13.0 and earlier contains an incorrect access control vulnerability in sql.php at lines 68-76. The application allows unauthorized manipulation of session variables by accepting user-controlled parameters ('subject', 'server', 'database', 'queryid') without proper validation or access control checks. Attackers can exploit this to store arbitrary SQL queries in $_SESSION['sqlquery'] by manipulating these parameters, potentially leading to session poisoning, stored cross-site scripting, or unauthorized access to sensitive session data.
