Last modified

CVE-2026-89059 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. A flaw was found in RESTEasy's IIOImageProvider, which decodes attacker-supplied image request bodies without enforcing any limit on the declared image dimensions or pixel count. A remote, unauthenticated attacker can send a small crafted image declaring enormous dimensions to trigger a very large memory allocation, exhausting the JVM heap and resulting in a denial of service.. EPSS estimates a 1.53% chance of exploitation in the next 30 days.
