A session management issue was addressed with improved checks. This issue is fixed in macOS Tahoe 26.2, macOS Sequoia 15.7.3, macOS Sonoma 14.8.3. A user with Voice Control enabled may be able to transcribe another users activity.
Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Macos | Apple | * | 14.8.3 (excluding) |
| Macos | Apple | 15.0 (including) | 15.7.3 (excluding) |
Such a scenario is commonly observed when:
In the generic exploit of session fixation vulnerabilities, an attacker creates a new session on a web application and records the associated session identifier. The attacker then causes the victim to associate, and possibly authenticate, against the server using that session identifier, giving the attacker access to the user’s account through the active session.
