Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper Restriction of XML External Entity Reference ('XXE') vulnerability in the Policy Engine of Forcepoint Data Loss Prevention (DLP), which is also leveraged by Forcepoint One Endpoint (F1E), Web Security Content Gateway, Email Security with DLP enabled, and Cloud Security Gateway prior to June 20, 2022. The XML parser in the Policy Engine was found to be improperly configured to support external entities and external DTD (Document Type Definitions), which can lead to an XXE attack. This issue affects: Forcepoint Data Loss Prevention (DLP) versions prior to 8.8.2. Forcepoint One Endpoint (F1E) with Policy Engine versions prior to 8.8.2. Forcepoint Web Security Content Gateway versions prior to 8.5.5. Forcepoint Email Security with DLP enabled versions prior to 8.5.5. Forcepoint Cloud Security Gateway prior to June 20, 2022.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

XXE vulnerability in Forcepoint DLP Policy Engine where the XML parser improperly supports external entities and external DTD processing. Attackers can inject malicious XML to read internal files, perform SSRF attacks, or cause denial of service by referencing external entities that may access local resources or trigger unintended network requests.

MitigationUpdate Forcepoint DLP and F1E to version 8.8.2 or later, Web Security/Email Security to 8.5.5 or later, and Cloud Security Gateway to the June 20, 2022 or later patch. Alternatively, configure the XML parser to disable external entity and external DTD processing.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Forcepoint product
    Locate the Forcepoint product installed in your environment. Common installation directories include /opt/forcepoint/ or check system services for Forcepoint-related processes (e.g., dpdl, fwsvr, csg). Review installed software or running services to confirm the specific Forcepoint component.
    Affected if Any Forcepoint product from the affected list is installed (Cloud Security Gateway, Data Loss Prevention, Email Security, One Endpoint with Policy Engine, or Web Security Content Gateway).
  2. Determine product version
    Check the installed version of the identified Forcepoint product. Common methods: check the software GUI About section, run 'dpdl --version' or 'fwsvr --version' from command line if available, or inspect version files in the installation directory (often in /opt/forcepoint/<product>/version or similar).
    Affected if Version cannot be determined or is below the safe threshold.
  3. Compare against affected version ranges
    Match your installed version to the affected ranges: Cloud Security Gateway < 2022-06-20, Data Loss Prevention < 8.8.2, Email Security < 8.5.5, One Endpoint With Policy Engine < 8.8.2, Web Security Content Gateway < 8.5.5.
    Affected if Installed version falls below the specified threshold for your product.
  4. Locate XML parser configuration
    Search for XML parser or XML processing configuration files within the Forcepoint installation directory. Look for files containing xml, parser, or xxe in the name. Common paths may include /opt/forcepoint/dlp/config/ or similar. Review configuration for settings related to external entity processing.
    Affected if External entity or external DTD processing is enabled in the XML parser configuration (e.g., feature for external entities is not explicitly disabled).

You are affected if your installed Forcepoint product version is below 8.8.2 (DLP/One Endpoint) or 8.5.5 (Email/Web Security) or predates June 20, 2022 (Cloud Security Gateway) AND the XML parser has external entity/external DTD processing enabled.

Interim mitigation

Update Forcepoint DLP and F1E to version 8.8.2 or later, Web Security/Email Security to 8.5.5 or later, and Cloud Security Gateway to the June 20, 2022 or later patch. Alternatively, configure the XML parser to disable external entity and external DTD processing.
