Security readout for executives and security teams

Plain-English summary

CVE-2020-7762 is an arbitrary file read issue in jsreport-chrome-pdf before 1.10.0. An authenticated, low-privileged attacker could potentially read files accessible to the service account, creating a confidentiality risk without needing user interaction.

Executive priority

Treat as a confidentiality-focused moderate priority. Upgrade during the next security maintenance window, faster for systems handling sensitive files or exposing PDF generation to many authenticated users.

Technical view

The record describes a network-reachable, low-complexity arbitrary file read vulnerability affecting jsreport-chrome-pdf versions before 1.10.0. CVSS 3.1 is 6.5 with high confidentiality impact, no integrity or availability impact, and low privileges required.

Likely exposure

Exposure is most likely in applications using jsreport-chrome-pdf below 1.10.0, especially where authenticated users can invoke PDF generation. The source data does not identify broader affected products or deployment patterns.

Exploitation context

The CVSS vector indicates proof-of-concept exploit maturity, but the source bundle does not cite active exploitation. The CVE is not listed as CISA KEV in the provided data.

Researcher notes

The available sources identify the package, version boundary, CVSS vector, and fix reference, but do not provide detailed exploitation prerequisites beyond low privileges and network access. Avoid assuming unauthenticated impact or active exploitation.

Mitigation direction

  • Upgrade jsreport-chrome-pdf to 1.10.0 or later.
  • Check vendor guidance and the referenced fix commit for implementation context.
  • Restrict PDF generation access to trusted authenticated users where possible.
  • Run the PDF service with least-privilege filesystem access.
  • Review secrets and sensitive files accessible to the service account.

Validation and detection

  • Inventory package manifests and lockfiles for jsreport-chrome-pdf versions below 1.10.0.
  • Confirm whether vulnerable systems expose PDF generation over network-accessible application paths.
  • Verify deployed artifacts actually include the upgraded package version.
  • Review application logs for unusual PDF generation or file access patterns.
  • Confirm service accounts cannot read unnecessary secrets or host files.
