Security readout for executives and security teams
Plain-English summary
Readdle Documents for iOS before 6.9.7 could show a malicious folder name in its file-transfer web server in a way that runs script in a user's browser. A victim would generally need to receive and extract an attacker-supplied ZIP archive first.
Executive priority
Treat this as a targeted mobile data-exposure risk, not an internet-wide emergency. Prioritize updating affected managed iOS devices and educating users who handle external archives.
Technical view
The issue is stored XSS in the Documents app file-transfer web server caused by improper display of directory names. The CVE record names versions before 6.9.7. No CVSS score, CWE, CPE, or vendor advisory details are included in the provided sources.
Likely exposure
Exposure is likely limited to iOS users with Documents by Readdle before 6.9.7 who use the app's file-transfer web server and may extract untrusted ZIP archives.
Exploitation context
The provided CVE text says user interaction is required and there is no known direct way to create the crafted directory name on a victim device. KEV is false, and the bundle provides no evidence of active exploitation.
Researcher notes
Evidence is sparse. The CVE description provides the vulnerable component, version boundary, and interaction requirement, but no CVSS vector, CWE, exploit telemetry, or detailed vendor remediation beyond the pre-6.9.7 version range.
Mitigation direction
- Update Documents by Readdle to 6.9.7 or later, preferably the current App Store release.
- Check Readdle or App Store guidance for current supported versions and security notes.
- Avoid extracting ZIP archives from untrusted or unexpected senders in the app.
- Limit use of the file-transfer web server to trusted networks and only when needed.
Validation and detection
- Inventory managed iOS devices for Documents by Readdle versions before 6.9.7.
- Confirm whether affected users use the app's file-transfer web server.
- Review user reports for unexpected ZIP files or suspicious directory names.
- Verify remediation by confirming app version 6.9.7 or later on enrolled devices.
