CVE-2025-3522

Leak of hashed Window credentials via crafted attachment URL

Thunderbird processes the X-Mozilla-External-Attachment-URL header to handle attachments which can be hosted externally. When an email is opened, Thunderbird accesses the specified URL to determine file size, and navigates to it when the user clicks the attachment. Because the URL is not validated or sanitized, it can reference internal resources like chrome:// or SMB share file:// links, potentially leading to hashed Windows credential leakage and opening the door to more serious security issues. This vulnerability was fixed in Thunderbird 137.0.2 and Thunderbird 128.9.2.

CVE-2026-40299

next-intl has an open redirect vulnerability

next-intl provides internationalization for Next.js. Applications using the `next-intl` middleware prior to version 4.9.1with `localePrefix: 'as-needed'` could construct URLs where path handling and the WHATWG URL parser resolved a relative redirect target to another host (e.g. scheme-relative `//` or control characters stripped by the URL parser), so the middleware could redirect the browser off-site while the user still started from a trusted app URL. The problem has been patchedin `next-intl@4.9.1`.

Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.16.1, Directus is vulnerable to an open redirect via the redirect query parameter on the /admin/tfa-setup page.

After completing the setup process, the application redirects the user to the attacker-controlled URL specified in the redirect parameter without any validation. This vulnerability could be used in phishing attacks targeting Directus administrators, as the initial interaction occurs on a trusted domain. This vulnerability is fixed in 11.16.1.
