CVE-2026-75686Network attack vector

Code execution via improperly validated URL input

Published Sep 22, 2026 · Updated Sep 22, 2026

Improper input validation in Adobe Connect allows remote attackers to execute code after a victim opens a crafted URL. The public record does not identify the input field, parser, or request handler that accepts and mishandles the crafted URL. Affected releases are Adobe Connect 12.11 and earlier and Adobe Connect Android Mobile App 4.4 and earlier; exploitation runs code as the current user and requires the victim to visit the malicious URL or use a compromised page.
