CVE-2023-2264

Code injection via crafted malicious link

Published Nov 30, 2023 · Updated Jun 3, 2025

Improper input validation in SEL-411L allows local users to trigger code injection by inducing an authorized user to open a crafted link. SEL has not published the affected component, accepted input, or the operation that converts the crafted link into injected code. Exploitation requires high local privileges and authorized-user interaction; SEL does not specify which data, process, or relay function can be altered.
