CVE-2026-34615 is a critical vulnerability in Adobe Connect that arises from deserialization of untrusted data, allowing attackers to execute arbitrary code as the current user. This vulnerability affects Adobe Connect versions 2025.3, 12.10, and earlier. Exploitation requires user interaction, such as visiting a crafted URL or interacting with a malicious web page, and can lead to elevated privileges or session compromise. The vulnerability changes the security scope and has a CVSS 3.1 base score of 9.3 (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N). Currently, no patch or official remediation level has been published by Adobe, and no exploits are known to be active in the wild.

Successful exploitation can result in arbitrary code execution with the privileges of the current user, potentially allowing attackers to inject malicious scripts, elevate access, or take control of the victim's account or session. The vulnerability affects confidentiality and integrity with high impact, but does not affect availability. The scope of the vulnerability is changed, meaning it can affect resources beyond the initially vulnerable component.
