CVE-2024-55950Public exploit

Local TCC bypass via injectable application entitlements

Published Dec 26, 2024 · Updated Dec 27, 2024

TCC bypass in Tabby before 1.0.216 allows local users to access protected files and devices through injected code. The macOS application enables DYLD environment variables while disabling library validation, allowing an attacker-supplied library to execute with Tabby's camera, microphone, Apple Events, and personal-folder entitlements. Exploitation requires existing local code execution and relevant TCC grants, after which injected code can read protected folders or access protected hardware without a separate consent prompt.
