Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A local privilege escalation vulnerability exists in the XPC service helper (com.x1a0he.macOS.Adobe-Downloader.helper) of the Adobe Downloader application for macOS. The shouldAcceptNewConnection function implements improper privilege management, allowing a local attacker to potentially bypass authorization checks and interact with the privileged XPC service.
