CVE-2026-34615 is a critical vulnerability in Adobe Connect involving deserialization of untrusted data. This flaw allows remote attackers to execute arbitrary code in the context of the current user without requiring user interaction. The vulnerability affects Adobe Connect versions 2025.3, 12.10, and earlier. The CVSS v3.1 base score is 9.3, indicating high severity with network attack vector, low attack complexity, no privileges required, and user interaction required. The scope is changed, and the impact includes high confidentiality and integrity impact but no availability impact. No patch or official remediation level has been disclosed by Adobe as of the publication date.

Successful exploitation could lead to arbitrary code execution under the current user's privileges, potentially compromising confidentiality and integrity of the affected system. Since no user interaction is required, the vulnerability could be exploited remotely. There are no known exploits in the wild at this time. The vulnerability does not affect availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, organizations should monitor Adobe's security advisories for updates. Given the critical severity and potential for remote code execution, consider applying temporary mitigations such as restricting network access to Adobe Connect services or running the application with least privilege where feasible.
