Exploitation
- Adobe is not aware of any exploits in the wild for the issues in APSB26-191.
- No public proof of concept found.
- NVD analysis is pending at the time of writing.
Our recommendation
- Identify all Adobe Connect instances and their exact versions.
- Update affected instances to the fixed version listed in APSB26-191 as a priority, since the vulnerability requires no privileges.
- Do not expose Connect servers directly to the internet; limit access to required users and networks.
- Review web and database logs for SQL injection attempts.
- Re-check NVD and CISA KEV for changes.
