Kingsoft WPS Office vulnerability
Kingsoft WPS Office contains a path traversal vulnerability in promecefpluginhost.exe allowing arbitrary Windows library loading.
Verdict
Today item — known-exploited.
A path traversal flaw in WPS Office's plugin host enables local attackers to load malicious libraries, potentially achieving code execution. Active exploitation in the wild increases risk despite low EPSS score.

Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
8 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2024-09-03).
Probability (EPSS)
EPSS 0.01773 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 9.3 (CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/AU:N/RE:L) · Affected: Kingsoft, WPS Office. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 4.0, set at disclosure.
Weakness (CWE)
Mapped to CWE-22 Path Traversal — weakness family: Path traversal / file.CWE — CNA-assigned (CVE.org); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: no · Technical Impact: totalCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog 19 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.

Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious Windows library and place it in a traversable directory path that the vulnerable plugin host will load.
Business
Unauthorized code execution on user systems running WPS Office compromises data confidentiality and system integrity.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I exploit the path traversal to redirect library loading to my payload, executing with the privileges of the WPS Office process.
Business
Attackers gain persistent access to user machines, enabling theft of sensitive documents and lateral movement within networks.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
