CVE-2026-27565: Remote code execution via uploading a malicious IODD file

CriticalCVSS 9.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 39/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.96% (FIRST EPSS); higher than 62.2% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
Fixed version: Carlo Gavazzi Automation YL212CEI8M1IO 1.7.4; Carlo Gavazzi Automation YL212CPN8M1IO 1.7.4; Carlo Gavazzi Automation YN115CEI8RPIO 1.7.4.

Low priority for now. Upgrade to Carlo Gavazzi Automation YL212CEI8M1IO 1.7.4; Carlo Gavazzi Automation YL212CPN8M1IO 1.7.4; Carlo Gavazzi Automation YN115CEI8RPIO 1.7.4 or later.
