## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-121900 (Adobe Connect | Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') (CWE-89)), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-121900 (entry last updated 2026-11-10):
Affected:
- Adobe Adobe Connect: through 12.8
- Adobe Adobe Connect: through 12.9
- Adobe Adobe Connect: through 12.10
- Adobe Adobe Connect: through 12.11
- Adobe Adobe Connect: through 12.12
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- Adobe Connect 12.12 and earlier on Windows (source: https://www.adobe.com/trust/security/products/connect/apsb26-191.html)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, low-privilege login, no user action.
CISA KEV: CVE-2026-121900 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-121900 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
- https://www.adobe.com/trust/security/products/connect/apsb26-191.html
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

## FAQ

### Is CVE-2026-121900 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

Source: https://cve.now/CVE-2026-121900

### What does this mean?

The bug is an SQL injection flaw: Adobe Connect does not properly neutralize special characters in input that is placed into database queries, so crafted input can change how those queries run. The advisory's impact rating for this issue is arbitrary code execution in the context of the current user.

Source: https://www.adobe.com/trust/security/products/connect/apsb26-191.html

### Which versions are affected by CVE-2026-121900?

Adobe Connect: through 12.8. Adobe Connect: through 12.9. Adobe Connect: through 12.10. Adobe Connect: through 12.11. Adobe Connect: through 12.12.
