CVE-2023-23301 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. The `news` MonkeyC operation code in CIQ API version 1.0.0 through 4.1.7 fails to check that string resources are not extending past the end of the expected sections. A malicious CIQ application could craft a string that starts near the end of a section, and whose length extends past its end. EPSS estimates a 1.06% chance of exploitation in the next 30 days.
