Is CVE-2024-7262 (Kingsoft WPS Office Path Traversal) being exploited in the wild?

Yes. CISA added CVE-2024-7262 to its Known Exploited Vulnerabilities catalogue on 3 September 2024, which it does only when there is reliable evidence of active exploitation. CISA has not linked it to known ransomware campaigns. Kingsoft WPS Office contains a path traversal vulnerability in promecefpluginhost.exe on Windows that allows an attacker to load an arbitrary Windows library.

How CISA’s KEV listing answers the “exploited in the wild” question

CISA’s Known Exploited Vulnerabilities catalogue is the practical signal practitioners use when they want to know whether a flaw has crossed from theoretical risk into active exploitation. For CVE-2024-7262, the key point is not just that the bug exists, but that it has been treated as an exploitation priority because it was observed in real attacks.

That matters because “exploited in the wild” changes the response posture. A vulnerability shifts from routine backlog management to urgent exposure reduction, with attention on internet-facing assets, exposed user populations, and any system where the vulnerable component is installed and reachable.

The operational question is therefore less about debating whether exploitation is possible and more about confirming whether your environment contains the affected software path, whether the vulnerable binary is present on Windows endpoints or servers, and whether any evidence suggests abuse has already occurred. For prioritisation, CISA’s KEV entry should be treated as stronger guidance than generic severity-based queues, and the triage lens should start with CISA Known Exploited Vulnerabilities Catalog.

What the path traversal flaw can enable in practice

The vulnerability type matters because path traversal in a plugin host can be a stepping stone to code loading or execution in an application context that users may trust. In this case, the risk is not abstract file access alone; the issue can allow an attacker to influence which Windows library is loaded, which is why exploitation can become a direct execution path rather than a simple read-only issue.

That kind of behavior is especially important on endpoints where office productivity software is widely deployed, patched unevenly, or allowed to run with user privileges that can still reach sensitive documents, browser sessions, or enterprise tools. Even when the initial flaw is narrow, the downstream effect can include local compromise, credential theft opportunities, and follow-on activity that is harder to distinguish from normal desktop software behavior.

Readers should anchor on the vulnerable product and record details using the official vulnerability sources, not on secondary commentary. The authoritative baseline is the CVE Program for the record itself and the NIST National Vulnerability Database for consolidated technical reference data.

What to do when exploitation is confirmed or suspected

Once a CVE is in KEV, the best next step is to assume exploitation is plausible until your environment proves otherwise. That means identifying where Kingsoft WPS Office is deployed, validating whether the vulnerable Windows component exists, and checking whether security tooling has recorded unusual library loading, process execution, or suspicious file activity around promecefpluginhost.exe.

If patching or mitigation must wait, the practical interim move is to narrow exposure: reduce unnecessary installation, restrict execution on high-value systems, monitor for suspicious child processes and anomalous library paths, and isolate endpoints that show signs of abuse. Because the flaw sits in software that users routinely open, post-exploitation review should include user profile changes, newly dropped files, and any evidence of lateral movement from the affected host.

For prioritisation, use exploitability evidence, not just product prevalence. The most useful supporting discipline is a vulnerability triage process that combines KEV status, asset exposure, and verification of remediation status, which is the same logic outlined in Zero-Day and Exploited Vulnerabilities Guide and Vulnerability Management Guide.

Risk and Threat Considerations

When a public application flaw is already in KEV, the main risk is not merely that some systems remain unpatched, but that exploitation can be happening before defenders finish asset discovery. That creates a race between remediation and compromise assessment, especially where desktop software is present on many endpoints and local activity may blend into normal user behavior.

Failure mechanism: The traversal weakness can let an attacker influence file resolution and library loading, turning a software handling flaw into a practical execution or persistence path on Windows hosts.

Impact: Successful abuse can expose user systems to code execution, data access, and follow-on compromise, so defenders should treat unexplained WPS Office activity on exposed systems as a potential incident indicator.

Standards & Framework Alignment

This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.

NIST CSF 2.0, NIST SP 800-53 Rev 5 and CIS Controls v8 set the governance and control requirements practitioners need to meet.

Framework	Control / Reference	Relevance
NIST CSF 2.0	DE.CM-01 — Monitoring for Anomalies and Events	Active exploitation needs detection of suspicious host and software behavior.
	ID.RA-01 — Vulnerability and Threats Identified	KEV status requires rapid recognition that the flaw is being exploited.
Recommendation — Monitor endpoints for abnormal process, file, and library-loading activity tied to the vulnerable app. Prioritize remediation using KEV status and verified asset exposure.
NIST SP 800-53 Rev 5	SI-2 — Flaw Remediation	The question is operationally about urgent remediation of an actively exploited flaw.
	SI-4 — System Monitoring	Suspected exploitation requires host-level monitoring for suspicious execution and library loading.
Recommendation — Remediate the vulnerable software quickly and verify the fix across the environment. Increase monitoring on endpoints for process, file, and DLL-loading anomalies.
CIS Controls v8	CIS-7 — Continuous Vulnerability Management	KEV-listed exploitation is a vulnerability management prioritization problem.
Recommendation — Use KEV status to accelerate remediation and validate exposure closure.

Practitioner Guidance

What to prioritise: Verify exposure first, then determine whether the vulnerable executable is installed on endpoints that matter. In a KEV-driven event, a clean inventory is more valuable than a broad “patch later” plan.

What to verify: Confirm whether any affected hosts show post-exploitation signals, especially suspicious library loads, unexpected child processes, new persistence, or file changes near the application path. If you cannot verify absence of abuse, treat the system as potentially compromised until proven otherwise.

Practitioner takeaway: For a KEV-listed flaw, the decisive question is not whether exploitation is technically possible, but whether you can prove your exposure is removed and your affected hosts are clean.
