CVE-2020-9566

User-context code execution via use-after-free

Published Jun 26, 2020 · Updated May 5, 2025

Use-after-free in Adobe Bridge 10.0.1 and earlier allows attackers to execute arbitrary code after required user interaction. Adobe has not published the affected component or the stale-object operation that causes the freed memory to be reused. Successful exploitation runs code in the context of the current user, bounding access to that user's privileges.
