> [!NOTE] > Message from the Pterodactyl team: > > The Pterodactyl team has evaluated this as a minor security issue but does not consider it something that should be assigned a CVE, nor does it require active patching by vulnerable systems. > > This issue is entirely self-inflicted and requires an administrative user paste an _obviously_ incorrect value into a database host field, submit it, and run into the XSS when the error message is rendered. However, we have determined that this fix is good security hygiene and may prevent issues in other areas not yet discovered. ### Summary When an administrative user creates a new database host they are prompted to provide a `Host` value which is expected to be a domain or IP address. When an invalid value is encountered and passed back to `gethostaddr` and/or directly to the MySQL connection tooling, an error is returned. This error is then passed back along to the front-end, but was not properly sanitized when rendered. Therefore it is po...

### Summary A stored cross-site scripting (XSS) vulnerability allows an attacker to execute arbitrary JavaScript in an administrator’s browser by registering a user whose **display name** contains HTML entities (e.g., `<img ...>`). When an administrator views the admin user list, the payload is decoded server-side and rendered without escaping, resulting in script execution in the admin context. ### Details Root cause is the following chain: - **User-controlled input stored**: attacker-provided `display_name` (real name) is stored in DB (often as HTML entities, e.g., `<img ...>`). - **Decode on read**: `phpmyfaq/src/phpMyFAQ/User/UserData.php` decodes `display_name` using `html_entity_decode(...)` (“for backward compatibility”). - **Unsafe sink**: admin user list renders the decoded value unescaped using Twig `|raw`: - `phpmyfaq/assets/templates/admin/user/users.twig` (users table uses `{{ user.display_name|raw }}`) As a result, an entity-encoded payload becomes active ...

In December 2024, the popular Ultralytics AI library was compromised, installing malicious code that hijacked system resources for cryptocurrency mining. In August 2025, malicious Nx packages leaked 2,349 GitHub, cloud, and AI credentials. Throughout 2024, ChatGPT vulnerabilities allowed unauthorized extraction of user data from AI memory. The result: 23.77 million secrets were leaked through AI

### Summary A stored Cross-Site Scripting (XSS) vulnerability may occur in n8n when using the “Respond to Webhook” node. When this node responds with HTML content containing executable scripts, the payload may execute directly in the top-level window, rather than within the expected sandbox introduced in version 1.103.0. This behavior can enable a malicious actor with workflow creation permissions to execute arbitrary JavaScript in the context of the n8n editor interface. While session cookies (`n8n-auth`) are marked `HttpOnly` and cannot be directly exfiltrated, the vulnerability can facilitate Cross-Site Request Forgery (CSRF)-like actions from within the user’s authenticated session, potentially allowing: - Unauthorized reading of sensitive workflow data or execution history. - Unauthorized modification or deletion of workflows. - Insertion of malicious workflow logic or external data exfiltration steps. n8n instances that allow untrusted users to create workflows are particular...

In Gitea before 1.20.1, a forbidden URL scheme such as javascript: can be used for a link, aka XSS.

Gitea before 1.22.2 allows XSS because the search input box (for creating tags and branches) is v-html instead of v-text.

Cyber threats last week showed how attackers no longer need big hacks to cause big damage. They’re going after the everyday tools we trust most — firewalls, browser add-ons, and even smart TVs — turning small cracks into serious breaches. The real danger now isn’t just one major attack, but hundreds of quiet ones using the software and devices already inside our networks. Each trusted system can
