An unrestricted file upload vulnerability in the Add New Assets function of Strapi 4.1.12 allows attackers to conduct XSS attacks via a crafted PDF file. NOTE: the project documentation suggests that a user with the Media Library "Create (upload)" permission is supposed to be able to upload PDF files containing JavaScript, and that all files in a public assets folder are accessible to the outside world (unless the filename begins with a dot character). The administrator can choose to allow only image, video, and audio files (i.e., not PDF) if desired.

Security readout for executives and security teams

Plain-English summary

This issue concerns Strapi 4.1.12 allowing permitted Media Library users to upload PDF files that may contain JavaScript. If those files are publicly accessible, a victim who opens a crafted PDF could face XSS-style browser risk. The CVE note says this behavior may align with Strapi documentation and configuration choices.

Executive priority

Prioritize as moderate when content contributors or external users can upload media. If only trusted administrators can upload PDFs, urgency is lower, but the configuration should still be reviewed because public assets can be externally accessible.

Technical view

CVE-2022-32114 describes unrestricted file upload in Strapi's Add New Assets function enabling XSS via crafted PDFs. The record notes users with Media Library Create upload permission can upload PDFs, public assets are externally accessible unless dot-prefixed, and administrators can restrict allowed media types to image, video, and audio.

Likely exposure

Exposure is most likely in Strapi 4.1.12 deployments where non-admin or less-trusted users have Media Library Create upload permission and PDF uploads remain allowed in public assets.

Exploitation context

The provided sources do not show KEV listing or active exploitation evidence. Exploitation appears to require upload permission and a victim interacting with the uploaded crafted PDF.

Researcher notes

Evidence is nuanced: the CVE note says Strapi documentation permits PDF uploads with JavaScript for users granted upload permission. No CVSS, CWE, CPE, patch, or KEV signal is provided. Treat validation as a configuration and trust-boundary assessment, not proof of universal exposure.

Mitigation direction

  • Restrict Media Library Create upload permission to trusted administrators only.
  • Disable PDF uploads where business workflows do not require them.
  • Review public asset exposure and avoid publishing untrusted uploaded files.
  • Check Strapi vendor guidance for supported versions and any remediation.
  • Document the accepted risk if PDF uploads must remain enabled.

Validation and detection

  • Inventory Strapi instances and confirm whether version 4.1.12 is present.
  • Review administrator roles for Media Library Create upload permission.
  • Check allowed media types for PDF acceptance.
  • Audit public asset storage for unexpected or user-supplied PDFs.
  • Review upload logs for unusual PDF upload activity.
