Roundcube vs SlickText: at a glance
What is Roundcube?
Roundcube patches 28+ vulnerabilities across two branches in a five-month hardening sprint
Roundcube has shipped six security releases across its main 1.7.x and LTS 1.6.x branches since June, patching a cumulative 28+ vulnerabilities including an RCE via the markasjunk plugin's cmd_learn driver, IMAP command injection through LITERAL+ byte-count desynchronization, multiple SSRF bypasses, cross-user contact group access, and zero-click stored XSS. The simultaneous dual-branch cadence shows active maintenance of both lines.
What is SlickText?
SlickText adds RCS, pushing past plain SMS into verified, branded business messaging.
SlickText runs a heavy SEO content engine — templates, listicles, vertical guides, awards posts — but the substantive product move is the addition of basic RCS messaging, bringing verified business identity and richer formatting to a platform built on plain SMS. Everything else in the recent feed is marketing and category positioning.

Roundcube
5.0COMMS
Roundcube patches 28+ vulnerabilities across two branches in a five-month hardening sprint
◆ Current state
Roundcube has shipped six security releases across its main 1.7.x and LTS 1.6.x branches since June, patching a cumulative 28+ vulnerabilities including an RCE via the markasjunk plugin's cmd_learn driver, IMAP command injection through LITERAL+ byte-count desynchronization, multiple SSRF bypasses, cross-user contact group access, and zero-click stored XSS. The simultaneous dual-branch cadence shows active maintenance of both lines.
◆ Where it's heading
The volume and variety of external security reports — from Horizon3.ai, Samsung R&D, pwn.ai, and independent researchers — indicates Roundcube's attack surface is under sustained scrutiny. The 1.7.0 release in May introduced meaningful features (Markdown rendering, improved OAuth2/OIDC, mandatory public_html entry point), but the months since have been consumed by patching. Feature development on 1.7.x appears paused until the security debt settles.
◆ Prediction
Another paired security release across 1.7.x and 1.6.x is likely within 6-8 weeks given the cadence. The SSRF and CSS parsing issues have required multiple iterations to close fully, suggesting the hardening work isn't finished.
SlickText
3.8COMMS
SlickText adds RCS, pushing past plain SMS into verified, branded business messaging.
◆ Current state
SlickText runs a heavy SEO content engine — templates, listicles, vertical guides, awards posts — but the substantive product move is the addition of basic RCS messaging, bringing verified business identity and richer formatting to a platform built on plain SMS. Everything else in the recent feed is marketing and category positioning.
◆ Where it's heading
The product is broadening from SMS-only toward a multi-format messaging stack where channel trust and branding matter. RCS gives SlickText a credible answer to the deliverability and impersonation problems that plain text marketing can't solve on its own, and slots it against enterprise rivals it keeps writing comparison content about.
◆ Prediction
Expect RCS to move from 'basic' to feature-complete — branded sender profiles, rich cards, and read receipts — and to become a headline differentiator in the comparison content SlickText already publishes against Attentive and EZ Texting.
