CVE-2025-5255

Severity CVSS v4.0:
MEDIUM
Type:
Unavailable / Other

Description

The Phoenix Code&amp;#39;s configuration on macOS, specifically the presence of entitlements: "com.apple.security.cs.allow-dyld-environment-variables" and "com.apple.security.cs.disable-library-validation" allows for Dynamic Library (Dylib) injection. A local attacker with unprivileged access can use environment variables like DYLD_INSERT_LIBRARIES to successfully inject code in application&amp;#39;s context and bypass Transparency, Consent, and Control (TCC). Acquired resource access is limited to previously granted permissions by the user. Access to other resources beyond granted-permissions requires user interaction with a system prompt asking for permission.<br /> <br /> This issue was fixed in commit 0c75fb57f89d0b7d9b180026bc2624b7dcf807da
