AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Slate Digital Connect for macOS has a TOCTOU race condition in its privileged helper tool, allowing local attackers to escalate privileges.
Vulnerability
Slate Digital Connect version 1.37.0 for macOS installs a privileged helper tool, com.slatedigital.connect.privileged.helper.tool, located in /Library/PrivilegedHelperTools. This tool exposes an XPC service, com.slatedigital.connect.privileged.helper.tool2, which performs client validation based on the connecting process's identifier (PID). This PID-based validation is susceptible to a time-of-check time-of-use (TOCTOU) race condition, as PIDs can be reused by the operating system [1].
Exploitation
A local attacker can exploit the TOCTOU race condition by manipulating the validation process. The attacker can cause the validation to be performed against a legitimate process while the actual connection is made by a different, potentially malicious, process. This allows the attacker to trick the privileged helper tool into granting access to its functionality as if the connection originated from a trusted source [1].
Impact
Successful exploitation of this vulnerability allows an attacker to gain unauthorized access to the functionality provided by the privileged helper tool. This can lead to local privilege escalation, enabling the attacker to execute commands or perform actions with elevated privileges, potentially up to the root user level on the affected macOS system [1].
Mitigation
As of the available information, the vendor has been unresponsive since January 2026, and no patch is available for this vulnerability. Users are advised to contact the vendor and demand a patch. There are no other workarounds or mitigations disclosed in the available references [1].

Vulnerability mechanics
Root cause
"The helper tool validates XPC clients using a process identifier (PID) which is susceptible to reuse, allowing a race condition."
Attack vector
A local attacker can exploit PID reuse to trick the helper tool into validating a different, trusted process than the one making the XPC request. This is achieved by carefully timing the execution of a malicious process that reuses the PID of a legitimate process after the legitimate process has been validated but before its request is fully processed. This allows the attacker to gain unauthorized access to the privileged helper tool's functionality, potentially leading to local privilege escalation [ref_id=1].
Affected code
The vulnerability lies within the `isValidClient` function of the `com.slatedigital.connect.privileged.helper.tool` XPC service. This function retrieves the client's process identifier (PID) using `_xpc_connection_get_pid()` and uses it to obtain code-signing information for validation [ref_id=1].
What the fix does
The advisory does not specify a patch or provide details on how the vulnerability is fixed. It notes that the vendor was unresponsive and a patch is not available as of January 2026. Users are advised to contact the vendor and demand a patch [ref_id=1].
Preconditions
- authThe attacker must have local access to the macOS system.
- configThe Slate Digital Connect application must be installed on the target system.
