# CVE-2024-7262: Kingsoft WPS Office Path Traversal Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Kingsoft WPS Office. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-09-03, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-09-24 ; treat that as the outer limit, not the target.
- EPSS 2.9% , percentile 87: FIRST’s model estimates a 2.9% chance of exploitation activity in the next 30 days, higher than 87% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.

## What it is

Improper path validation in promecefpluginhost.exe in Kingsoft WPS Office version ranging from 12.2.0.13110 to 12.2.0.16412 (exclusive) on Windows allows an attacker to load an arbitrary Windows library.
