TCC bypass via permissive macOS entitlements
Published Mar 17, 2025 · Updated Mar 31, 2025
Code injection exposure in Mattermost Desktop App 5.10.0 and earlier allows local users to bypass macOS TCC protections. The signing profiles unnecessarily grant allow-unsigned-executable-memory and allow-dyld-environment-variables, enabling injected code to run inside the entitled application context. A low-privileged local foothold, including remote access to the Mac, is required; the resulting access is limited to TCC-protected data.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
