CVE-2026-25786
Last modified
CVE-2026-25786 is a critical-severity vulnerability rated 9.3/10 on the CVSS scale. Affected devices do not properly validate and sanitize PLC/station name rendered on the "communication" parameters page of the web interface. This could allow an authenticated attacker who is authorized to download a TIA project into the product, to inject malicious scripts into the page. If a benign user with appropriate rights accesses the "communication" parameters page, the malicious code would be executed in the scope of their web session.. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
Description
