CERT Polska disclosed three vulnerabilities affecting DHTMLX software components used for diagramming, Gantt charts, and scheduling. Two of the flaws (CVE-2026-7182 and CVE-2026-41552) are path traversal issues in the Diagram export module and PDF Export Module respectively, stemming from insufficient HTML sanitization of the src attribute, allowing an unauthenticated user to embed local server files into generated PDFs. The third and most serious issue, CVE-2026-41553, is a remote code execution vulnerability in the PDF Export Module used by DHTMLX's Gantt and Scheduler products, caused by a lack of sanitization on a data parameter that is processed and executed by Node.js, potentially allowing full server compromise by an unauthenticated attacker.
All three vulnerabilities were responsibly disclosed by researchers Łukasz Jaworski and Tomasz Holeksa of Pentest Limited and coordinated through CERT Polska's CVD process. Vendor fixes are available: Diagram version 1.1.1 resolves CVE-2026-7182, and PDF Export Module version 0.7.6 addresses both CVE-2026-41552 and CVE-2026-41553. No evidence of active exploitation is mentioned in the advisory; this is a coordinated disclosure with patches already released.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
