### Impact The XML [`Validator`](https://docs.oracle.com/javase/8/docs/api/javax/xml/validation/Validator.html) used by cyclonedx-core-java was not configured securely, making the library vulnerable to XML External Entity (XXE) injection. The fix for GHSA-683x-4444-jxh8 / CVE-2024-38374 has been incomplete in that it only fixed *parsing* of XML BOMs, but not *validation*. ### Patches The vulnerability has been fixed in cyclonedx-core-java version 11.0.1. ### Workarounds If feasible, applications can reject XML documents before handing them to cyclonedx-core-java for validation. This may be an option if incoming CycloneDX BOMs are known to be in JSON format. ### References * The issue was introduced via https://github.com/CycloneDX/cyclonedx-core-java/commit/162aa594f347b3f612fe0a45071693c3cd398ce9 * The issue was fixed via https://github.com/CycloneDX/cyclonedx-core-java/pull/737 * https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html#sc...

Versions of the package cloudinary before 2.7.0 are vulnerable to Arbitrary Argument Injection due to improper parsing of parameter values containing an ampersand. An attacker can inject additional, unintended parameters. This could lead to a variety of malicious outcomes, such as bypassing security checks, altering data, or manipulating the application's behavior. **Note:** Following our established security policy, we attempted to contact the maintainer regarding this vulnerability, but haven't received a response.

A vulnerability was detected in EverShop up to 2.0.1. Affected is an unknown function of the file /src/modules/oms/graphql/types/Order/Order.resolvers.js of the component Order Handler. The manipulation of the argument uuid results in improper control of resource identifiers. The attack may be performed from remote. This attack is characterized by high complexity. The exploitability is told to be difficult. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

### Impact The prosemirror_to_html gem is vulnerable to Cross-Site Scripting (XSS) attacks through malicious HTML attribute values. While tag content is properly escaped, attribute values are not, allowing attackers to inject arbitrary JavaScript code. **Who is impacted:** - Any application using prosemirror_to_html to convert ProseMirror documents to HTML - Applications that process user-generated ProseMirror content are at highest risk - End users viewing the rendered HTML output could have malicious JavaScript executed in their browsers **Attack vectors include:** - `href` attributes with `javascript:` protocol: `<a href="javascript:alert(document.cookie)">` - Event handlers: `<div onclick="maliciousCode()">` - `onerror` attributes on images: `<img src=x onerror="alert('XSS')">` - Other HTML attributes that can execute JavaScript ### Patches A fix is currently in development. Users should upgrade to version **0.2.1** or later once released. The patch escapes all HTML ...

### Overview This report **demonstrates a real-world privilege escalation** vulnerability in [pdfminer.six](https://github.com/pdfminer/pdfminer.six) due to unsafe usage of Python's `pickle` module for CMap file loading. It shows how a low-privileged user can gain root access (or escalate to any service account) by exploiting insecure deserialization in a typical multi-user or server environment. ## Table of Contents - [Background](#-background) - [Vulnerability Description](#-vulnerability-description) - [Demo Scenario](#-demo-scenario) - [Technical Details](#-technical-details) - [Setup and Usage](#-setup-and-usage) - [Step-by-step Walkthrough](#-step-by-step-walkthrough) - [Security Standards & References](#-security-standards--references) --- ## Background **pdfminer.six** is a popular Python library for extracting text and information from PDF files. It supports CJK (Chinese, Japanese, Korean) fonts via external CMap files, which it loads from disk using Python's `pickle` m...

### Summary pdfminer.six will execute arbitrary code from a malicious pickle file if provided with a malicious PDF file. The `CMapDB._load_data()` function in pdfminer.six uses `pickle.loads()` to deserialize pickle files. These pickle files are supposed to be part of the pdfminer.six distribution stored in the `cmap/` directory, but a malicious PDF can specify an alternative directory and filename as long as the filename ends in `.pickle.gz`. A malicious, zipped pickle file can then contain code which will automatically execute when the PDF is processed. ### Details ```python # Vulnerable code in pdfminer/cmapdb.py:233-246 def _load_data(cls, name: str) -> Any: name = name.replace("\0", "") # Insufficient sanitization filename = "%s.pickle.gz" % name # ... path construction ... path = os.path.join(directory, filename) # If filename is an absolte path, directory is ignored # ... return type(str(name), (), pickle.loads(gzfile.read())) # Unsafe deserializatio...

### Summary The `hostDisk` feature in KubeVirt allows mounting a host file or directory owned by the user with UID 107 into a VM. However, the implementation of this feature and more specifically the `DiskOrCreate` option which creates a file if it doesn't exist, has a logic bug that allows an attacker to read and write arbitrary files owned by more privileged users on the host system. ### Details The `hostDisk` feature gate in KubeVirt allows mounting a QEMU RAW image directly from the host into a VM. While similar features, such as mounting disk images from a PVC, enforce ownership-based restrictions (e.g., only allowing files owned by specific UID, this mechanism can be subverted. For a RAW disk image to be readable by the QEMU process running within the `virt-launcher` pod, it must be owned by a user with UID 107. **If this ownership check is considered a security barrier, it can be bypassed**. In addition, the ownership of the host files mounted via this feature is changed to th...

AstrBot Project v3.5.22 has an arbitrary file read vulnerability in function _encode_image_bs64. Since the _encode_image_bs64 function defined in entities.py opens the image specified by the user in the request body and returns the image content as a base64-encoded string without checking the legitimacy of the image path, attackers can construct a series of malicious URLs to read any specified file, resulting in sensitive data leakage.

AstrBot Project v3.5.22 contains a directory traversal vulnerability. The handler function install_plugin_upload of the interface '/plugin/install-upload' parses the filename from the request body provided by the user, and directly uses the filename to assign to file_path without checking the validity of the filename. The variable file_path is then passed as a parameter to the function `file.save`, so that the file in the request body can be saved to any location in the file system through directory traversal.

### Summary Open WebUI v0.6.33 and below contains a code injection vulnerability in the Direct Connections feature that allows malicious external model servers to execute arbitrary JavaScript in victim browsers via Server-Sent Event (SSE) `execute` events. This leads to authentication token theft, complete account takeover, and when chained with the Functions API, enables remote code execution on the backend server. The attack requires the victim to enable Direct Connections (disabled by default) and add the attacker's malicious model URL, achievable through social engineering of the admin and subsequent users. ### Details ROOT CAUSE ANALYSIS: Open WebUI's Direct Connections feature allows users to add external OpenAI-compatible model servers without proper validation of the Server-Sent Events (SSE) these servers emit. VULNERABLE COMPONENT: Frontend SSE Event Handler The frontend JavaScript code processes SSE events from external servers and specifically handles an `execute` eve...
