### Summary The HAX CMS API endpoints do not perform authorization checks when interacting with a resource. Both the JS and PHP versions of the CMS do not verify that a user has permission to interact with a resource before performing a given operation. ### Details The API endpoints within the HAX CMS application check if a user is authenticated, but don't check for authorization before performing an operation. #### Affected Resources - [Operations.php: 760](https://github.com/haxtheweb/haxcms-php/blob/b158d8ba1f9602af92ab084fd03b418f953079fd/system/backend/php/lib/Operations.php#L760) `createNode()` - [Operations.php: 868](https://github.com/haxtheweb/haxcms-php/blob/b158d8ba1f9602af92ab084fd03b418f953079fd/system/backend/php/lib/Operations.php#L868) `saveNode()` - [Operations.php: 1171](https://github.com/haxtheweb/haxcms-php/blob/b158d8ba1f9602af92ab084fd03b418f953079fd/system/backend/php/lib/Operations.php#L1171) `deleteNode()` - [Operations.php: 1789](https://github.com/haxth...

## Summary An inconsistency in `MethodNode` can be exploited to access unexpected object fields through dot notation. This can be used to achieve **arbitrary code execution at load time**. While this issue may seem similar to https://github.com/skops-dev/skops/security/advisories/GHSA-m7f4-hrc6-fwg3, it is actually more severe, as it relies on fewer assumptions about trusted types. ## Details The `MethodNode` allows access to attributes of existing objects via dot notation. However, there are several critical shortcomings: * Although the `__class__` and `__module__` fields are checked via `get_untrusted_types` and during the `load` phase (as a concatenated string), **they are not actually used by `MethodNode`**. Instead, the `func` and `obj` entries in the `schema.json` are used to determine behavior. This means that even an apparently harmless `__module__.__class__` pair can lead to access of arbitrary attributes or methods of loaded objects, without any additional checks. * **...

## Summary An inconsistency in `OperatorFuncNode` can be exploited to hide the execution of untrusted `operator.xxx` methods. This can then be used in a code reuse attack to invoke seemingly safe functions and escalate to arbitrary code execution with minimal and misleading trusted types. **Note:** This report focuses on `operator.call` as it appears to be the most interesting target, but the same technique applies to other `operator` methods. Moreover, please do not focus too much on the specific example used to hide the `operator.call` invocation—it was a zero-effort choice meant solely to demonstrate the issue. The key point is the **inconsistency** that allows a user to approve a type as trusted, while in reality enabling the execution of `operator.xxx`. ## Details The `OperatorFuncNode` allows calling methods belonging to the `operator` module and included in a trusted list of methods. However, what is returned by `get_untrusted_types` and checked during the `load` call is no...

**Path-Traversal -> Arbitrary File Write in Assemblyline Service Client** --- ## 1. Summary The Assemblyline 4 **service client** (`task_handler.py`) accepts a SHA-256 value returned by the service **server** and uses it directly as a local file name. > No validation / sanitisation is performed. A **malicious or compromised server** (or any MITM that can speak to client) can return a path-traversal payload such as `../../../etc/cron.d/evil` and force the client to write the downloaded bytes to an arbitrary location on disk. --- ## 2. Affected Versions | Item | Value | |---|---| | **Component** | `assemblyline-service-client` | | **Repository** | [CybercentreCanada/assemblyline-service-client](https://github.com/CybercentreCanada/assemblyline-service-client) | | **Affected** | **All releases up to master branch.** | --- ## 4.

A vulnerability, which was classified as problematic, was found in KoaJS Koa up to 3.0.0. Affected is the function back in the library lib/response.js of the component HTTP Header Handler. The manipulation of the argument Referrer leads to open redirect. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.

### Summary A critical SQL Injection vulnerability exists in the `getLast` API functionality of the eKuiper project. This flaw allows unauthenticated remote attackers to execute arbitrary SQL statements on the underlying SQLite database by manipulating the table name input in an API request. Exploitation can lead to data theft, corruption, or deletion, and full database compromise. ### Details The root cause lies in the use of unsanitized user-controlled input when constructing SQL queries using `fmt.Sprintf`, without validating the `table` parameter. Specifically, in: ```go query := fmt.Sprintf("SELECT * FROM %s ORDER BY rowid DESC LIMIT 1", table) ``` Any value passed as the `table` parameter is directly interpolated into the SQL string, enabling injection attacks. This is reachable via API interfaces that expose time-series queries. ### PoC 1. **Deploy eKuiper instance** (default config is sufficient). 2. **Send a crafted request to the SQL query endpoint**: ```bash curl -X ...

### Summary A critical vulnerability exists in the form-data package used by `axios@1.10.0`. The issue allows an attacker to predict multipart boundary values generated using `Math.random()`, opening the door to HTTP parameter pollution or injection attacks. This was submitted in [issue #6969](https://github.com/axios/axios/issues/6969) and addressed in [pull request #6970](https://github.com/axios/axios/pull/6970). ### Details The vulnerable package `form-data@4.0.0` is used by `axios@1.10.0` as a transitive dependency. It uses non-secure, deterministic randomness (`Math.random()`) to generate multipart boundary strings. This flaw is tracked under [Snyk Advisory SNYK-JS-FORMDATA-10841150](https://security.snyk.io/vuln/SNYK-JS-FORMDATA-10841150) and [CVE-2025-7783](https://security.snyk.io/vuln/SNYK-JS-FORMDATA-10841150). Affected `form-data` versions: - <2.5.4 - >=3.0.0 <3.0.4 - >=4.0.0 <4.0.4 Since `axios@1.10.0` pulls in `form-data@4.0.0`, it is exposed to this issue. ### PoC...

### Summary The regular expression patched to mitigate the ReDoS vulnerability by limiting the length of string fails to catch inputs that exceed this limit. ### Details In version 3.0.1, you can find a commit like the one in the link below, which was made to prevent ReDoS. https://github.com/rennf93/fastapi-guard/commit/d9d50e8130b7b434cdc1b001b8cfd03a06729f7f This commit mitigates the vulnerability by limiting the length of the input string, as shown in the example below. `r"<script[^>]*>[^<]*<\\/script\\s*>"` -> `<script[^>]{0,100}>[^<]{0,1000}<\\/script\\s{0,10}>` This type of patch fails to catch cases where the string representing the attributes of a <script> tag exceeds 100 characters. Therefore, most of the regex patterns present in version 3.0.1 can be bypassed. ### PoC 1. clone the fastapi-guard repository 2. Navigate to the examples directory and modify the main.py source code. Change the HTTP method for the root route from GET to POST. <img width="1013" height="554" ...
