CVE-2026-45696

A flaw was found in the OpenEXR image library. If an application opens a maliciously crafted EXR image file, it triggers a memory error. An attacker can use this to crash the application—causing a denial of service (DoS)—and potentially view sensitive information from the application's memory. Any system that processes untrusted EXR files is at risk.

This flaw in the OpenEXR library allows attackers to crash applications or potentially view sensitive memory data by providing a specially crafted image file. Systems that automatically process untrusted EXR files (like asset pipelines or thumbnailers) are at the highest risk.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To minimize risk, avoid opening or processing EXR image files from untrusted or unknown sources. For environments that must process external files, run the handling applications within a sandboxed environment to restrict their privileges and limit the damage a potential exploit can cause.
