Security readout for executives and security teams
This is a WordPress plugin file-read issue. Vulnerable Duplicator versions can let an unauthenticated internet user read sensitive server files through directory traversal. CISA lists CVE-2020-11738 in KEV, and Wordfence reported active attacks, so exposed WordPress sites should be treated as urgent. Public WordPress sites running Duplicator plugin versions before 1.3.28 or Duplicator Pro before 3.8.7.1 are the primary concern. The provided affected CPE data is incomplete, so exposure must be confirmed from site inventories and plugin version data. High priority. KEV listing means known exploitation has occurred, and the impact can include exposure of sensitive files from WordPress servers. Organizations with public WordPress properties should verify versions and remediate promptly. Mitigation focus: Upgrade Duplicator to 1.3.28 or later.; Upgrade Duplicator Pro to 3.8.7.1 or later.; Prefer the latest vendor-supported release where operationally safe..

CWE-22: File access and web shell behavior lookup
File traversal and upload weaknesses can lead teams to review file, web shell, execution, and collection telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupFile access behavior lookup
The CVE wording references file access or upload behavior, so file telemetry and web shell review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
