CVE-2026-34615 is a deserialization of untrusted data vulnerability affecting Adobe Connect versions 2025.3, 12.10, and earlier. Improper handling of serialized input can allow attacker-controlled data to be deserialized in a way that leads to arbitrary code execution in the context of the current user. The available reporting also indicates a scope change, meaning successful exploitation can impact resources beyond the originally vulnerable component. Some reporting around exploitation prerequisites is inconsistent, but the vulnerability is described as remotely exploitable and capable of leading to script injection into web content and subsequent compromise of the victim account or session.
