CVE-2026-121906

Summary

Adobe Connect contains a path traversal vulnerability (CWE-22) allowing authenticated low-privilege users to read arbitrary files on the server by manipulating file paths outside the intended directory scope. This is due to insufficient validation of user-supplied path inputs.

Exploitability

Exploitation requires valid low-privilege authentication and no user interaction; the vulnerability is straightforward to exploit using standard path traversal sequences (e.g., ../../../etc/passwd).

Blast radius

Successful exploitation enables full compromise of confidentiality, integrity, and availability via access to sensitive configuration files, credentials, or system binaries, potentially leading to lateral movement or full server takeover.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to Adobe Connect version 12.6.5 or later, as patched in the vendor’s security advisory for CVE-2026-121906.
