### Summary A Cross-Site Scripting (XSS) vulnerability exists in the `ui.interactive_image` component of NiceGUI (v3.3.1 and earlier). The component renders SVG content using Vue's `v-html` directive without any sanitization. This allows attackers to inject malicious HTML or JavaScript via the SVG `<foreignObject>` tag. ### Details The vulnerability is located in `nicegui/elements/interactive_image.js`. The component uses the following code to render content: ```javascript <g v-html="content"></g> ``` Vue's v-html directive renders raw HTML strings into the DOM. If an application allows user-controlled input to be passed to the content property of an interactive image, an attacker can embed a <foreignObject> tag containing malicious scripts, bypassing typical image restrictions. ### PoC ```python from nicegui import ui @ui.page('/') def main(): ui.label('NiceGUI SVG XSS PoC') # Standard image loading img = ui.interactive_image('[https://picsum.photos/640/360](https:...

### Summary A Cross-Site Scripting (XSS) vulnerability exists in `ui.add_css`, `ui.add_scss`, and `ui.add_sass` functions in NiceGUI (v3.3.1 and earlier). These functions allow developers to inject styles dynamically. However, they lack proper sanitization or encoding for the JavaScript context they generate. An attacker can break out of the intended `<style>` or `<script>` tags by injecting closing tags (e.g., `</style>` or `</script>`), allowing for the execution of arbitrary JavaScript. ### Details The vulnerability stems from how these functions inject content into the DOM using `client.run_javascript` (or `add_head_html` internally) without sufficient escaping for the transport layer. * **`ui.add_css`**: Injects content into a `<style>` tag. Input containing `</style>` closes the tag prematurely, allowing subsequent HTML/JS injection. * **`ui.add_scss` / `ui.add_sass`**: These rely on client-side compilation within `<script>` tags. Input containing `</script>` breaks the execut...

Securonix Threat Research details the complex JS#SMUGGLER campaign, a three-step web attack using obfuscated JavaScript and hidden HTA files to install the NetSupport RAT on user Windows desktops, granting hackers full remote control and persistent access.

Cybersecurity researchers are calling attention to a new campaign dubbed JS#SMUGGLER that has been observed leveraging compromised websites as a distribution vector for a remote access trojan named NetSupport RAT. The attack chain, analyzed by Securonix, involves three main moving parts: An obfuscated JavaScript loader injected into a website, an HTML Application (HTA) that runs encrypted

Over 30 security vulnerabilities have been disclosed in various artificial intelligence (AI)-powered Integrated Development Environments (IDEs) that combine prompt injection primitives with legitimate features to achieve data exfiltration and remote code execution. The security shortcomings have been collectively named IDEsaster by security researcher Ari Marzouk (MaccariTA). They affect popular

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday formally added a critical security flaw impacting React Server Components (RSC) to its Known Exploited Vulnerabilities (KEV) catalog following reports of active exploitation in the wild. The vulnerability, CVE-2025-55182 (CVSS score: 10.0), relates to a case of remote code execution that could be triggered by an

## Summary Adding default PCR12 validation to ensure that account operators can not modify kernel command line parameters, potentially bypassing root filesystem integrity validation. Attestable AMIs are based on the systemd Unified Kernel Image (UKI) concept which uses systemd-boot to create a single measured UEFI binary from a Linux kernel, its initramfs, and kernel command line. The embedded kernel command line contains a dm-verity hash value that establishes trust in the root file system. When UEFI Secure Boot is disabled, systemd-boot appends any command line it receives to the kernel command line. Account operators with the ability to modify UefiData can install a boot variable with a command line that deactivates root file system integrity validation, while preserving the original PCR4 value. Systemd-boot provides separate measurement of command line modifications in PCR12. ## Impact In line with the TPM 2.0 specification and systemd-stub logic, KMS policies that do not inc...

### Impact **Excessive memory allocation** Function [api.ParseJSONRequest](https://github.com/sigstore/timestamp-authority/blob/26d7d426d3000abdbdf2df34de56bb92246c0365/pkg/api/timestamp.go#L63) currently splits (via a call to [strings.Split](https://pkg.go.dev/strings#Split)) an optionally-provided OID (which is untrusted data) on periods. Similarly, function [api.getContentType](https://github.com/sigstore/timestamp-authority/blob/26d7d426d3000abdbdf2df34de56bb92246c0365/pkg/api/timestamp.go#L114) splits the `Content-Type` header (which is also untrusted data) on an `application` string. As a result, in the face of a malicious request with either an excessively long OID in the payload containing many period characters or a malformed `Content-Type` header, a call to `api.ParseJSONRequest` or `api.getContentType` incurs allocations of O(n) bytes (where n stands for the length of the function's argument). Relevant weakness: [CWE-405: Asymmetric Resource Consumption (Amplification)](h...

A human rights lawyer from Pakistan's Balochistan province received a suspicious link on WhatsApp from an unknown number, marking the first time a civil society member in the country was targeted by Intellexa's Predator spyware, Amnesty International said in a report. The link, the non-profit organization said, is a "Predator attack attempt based on the technical behaviour of the infection

### Summary A Server-Side Request Forgery (SSRF) vulnerability in Open WebUI allows any authenticated user to force the server to make HTTP requests to arbitrary URLs. This can be exploited to access cloud metadata endpoints (AWS/GCP/Azure), scan internal networks, access internal services behind firewalls, and exfiltrate sensitive information. No special permissions beyond basic authentication are required. ### Details The vulnerability exists in the /api/v1/retrieval/process/web endpoint located in backend/open_webui/routers/retrieval.py at lines 1758-1767. Vulnerable code: @router.post("/process/web") def process_web( request: Request, form_data: ProcessUrlForm, user=Depends(get_verified_user) ): try: collection_name = form_data.collection_name if not collection_name: collection_name = calculate_sha256_string(form_data.url)[:63] content, docs = get_content_from_url(request, form_data.url) # ← SSRF vulnerability Th...
