CWE-648
Incorrect Use of Privileged APIs
The product does not conform to the API requirements for a function call that requires extra privileges. This could allow attackers to gain privileges by causing the function to be called incorrectly.
CVE-2026-54424 (GCVE-0-2026-54424)

Mitigation
Phase: Implementation
Description:
- Before calling privileged APIs, always ensure that the assumptions made by the privileged code hold true prior to making the call.
Mitigation
Phase: Architecture and Design
Description:
- Know architecture and implementation weaknesses of the privileged APIs and make sure to account for these weaknesses before calling the privileged APIs to ensure that they can be called safely.
Mitigation
Phase: Implementation
Description:
- If privileged APIs make certain assumptions about data, context or state validity that are passed by the caller, the calling code must ensure that these assumptions have been validated prior to making the call.
Mitigation
Phase: Implementation
Description:
- If privileged APIs do not shed their privilege prior to returning to the calling code, then calling code needs to shed these privileges immediately and safely right after the call to the privileged APIs. In particular, the calling code needs to ensure that a privileged thread of execution will never be returned to the user or made available to user-controlled processes.
Mitigation
Phase: Implementation
Description:
- Only call privileged APIs from safe, consistent and expected state.
Mitigation
Phase: Implementation
Description:
- Ensure that a failure or an error will not leave a system in a state where privileges are not properly shed and privilege escalation is possible (i.e. fail securely with regards to handling of privileges).
CAPEC-107: Cross Site Tracing
Cross Site Tracing (XST) enables an adversary to steal the victim's session cookie and possibly other authentication credentials transmitted in the header of the HTTP request when the victim's browser communicates to a destination system's web server.
CAPEC-234: Hijacking a privileged process
An adversary gains control of a process that is assigned elevated privileges in order to execute arbitrary code with those privileges. Some processes are assigned elevated privileges on an operating system, usually through association with a particular user, group, or role. If an attacker can hijack this process, they will be able to assume its level of privilege in order to execute their own code.
