CVE-2026-63357

5.3 medium SSVC exploitation: none Awaiting Analysis
NVD · CVE.org

Affected devices do not properly sanitize calculated signal data contained in imported calculated signal files before rendering it on the Trace page. This could allow an attacker to social engineer an authorized user who holds the function right “Read diagnostics” into importing a specially crafted file. Successful exploitation could allow attacker-controlled JavaScript to execute in the user’s browser session and perform PLC operations through the web server within the scope of the user’s authorization.

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
