TL;DR SnappyMail's maintainer published advisory, rating a SnappyMail RCE chain critical. The advisory includes full technical details, step-by-step logs and downloadable proof-of-concept exploit scripts. However, the flaw sits in code that never shipped in an official release. A trusted-header patch let attackers fake admin access and then install a malicious plugin. Researcher furkank1337 published working exploit scripts with the advisory. Only development builds that merged the patch and set an admin panel host are affected.

Tachyon is a self-hosted webmail application combining email, contacts and calendars without requiring a separate database. It connects directly to existing mail and groupware services using standard protocols and is designed to keep communication with the user’s own infrastructure rather than relying on external services. Tachyon descends from the RainLoop and SnappyMail codebases but has continued development of its interface, security, mobile behaviour and integration features. This is free and open source software. #### Key Features * Works with IMAP and SMTP servers for mailbox access and outgoing mail. * Supports Sieve for server-side mail filtering. * Provides CardDAV contacts with groups, photos, postal addresses, birthdays and bulk operations. * Includes CalDAV calendars with multiple views, recurring events, invitations and iCalendar import. * Supports multiple email accounts and OAuth authentication for Gmail, Microsoft and generic OAuth providers. * Offers OpenPGP, GnuPG, Mailvelope and S/MIME functionality for signed and encrypted messages. * Includes configurable undo-send functionality which delays delivery to SMTP. * Blocks remote images until explicitly allowed and stores trusted-sender preferences on the server. * Provides light, dark and system-following appearance modes across its bundled themes. * Supports swipe navigation between messages on touch devices. * Integrates with Nextcloud and can migrate an existing SnappyMail installation while retaining its data and configuration. * Includes an administrative interface for updates, branding, logging, calendar configuration and security settings. * Provides release signature verification, Content Security Policy headers, Subresource Integrity and restrictive browser permission policies. * Loads less frequently used components on demand to keep the initial browser payload comparatively small. **Website:** **github.com/kimusan/Tachyon** **Support:** **Developer:** kimusan **License:** GNU Affero General Public License v3.0 Tachyon is written in PHP and JavaScript.
