Adobe Connect: SQL injection allowing arbitrary SQL commands
Summary
Adobe Connect 12.12 and earlier on Windows contains an SQL injection flaw (CWE-89). An attacker with a low-privileged account can execute arbitrary SQL commands over the network without user interaction. The CVE description states that this can lead to arbitrary code execution in the context of the current user, but real impact depends on the database account privileges and server configuration. The CVSS base score is 8.3 (High), and Adobe fixes it in bulletin APSB26-191 together with other Connect vulnerabilities.
Affected
- Adobe Connect 0 to 12.8
- Adobe Connect 0 to 12.9
- Adobe Connect 0 to 12.10
- Adobe Connect 0 to 12.11
- Adobe Connect 0 to 12.12
- Platform: Windows
Fixed in
- Adobe Connect 12.8.a
- Adobe Connect 12.9.a
- Adobe Connect 12.10.f
- Adobe Connect 12.11.i

Workaround
- Unknown. No vendor workaround is listed in the sources.
- Restrict access to the Connect server to required users and networks.
Exploitation
- Adobe is not aware of any exploits in the wild for the issues in APSB26-191.
- No public proof of concept was found in research. This is not conclusive.
Our recommendation
- Update Adobe Connect on Windows to the fixed build for your branch (12.8.a, 12.9.a, 12.10.f, 12.11.i or 12.12.a) as listed in APSB26-191.
- Prioritise internet-facing Connect servers.
- Review user accounts, including guest and self-registered accounts, and remove unneeded ones.
- Check the privileges of the database account used by Connect.
- Monitor logs for SQL errors and unusual requests until patched.
- Apply the whole November 2026 Connect bulletin, not only this CVE.
