Security readout for executives and security teams
Plain-English summary
CVE-2026-28039 affects the WordPress wpDataTables plugin and may let an attacker include local files through unsafe PHP include handling. The reported impact is high, but the CVSS vector requires user interaction and high attack complexity. Public sources provided do not show known active exploitation.
Executive priority
Treat as a high-priority WordPress plugin issue for sites using wpDataTables, especially internet-facing sites. Prioritize inventory and vendor-guided remediation, but do not assume active exploitation from the available sources.
Technical view
The issue is CWE-98: improper control of filenames used in PHP include/require statements, described as PHP Local File Inclusion. Sources state wpDataTables versions through 6.5.0.1 are affected. CVSS 3.1 is 7.5 with AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H.
Likely exposure
WordPress environments using the wpDataTables plugin at versions up to and including 6.5.0.1. Exposure should be confirmed by checking installed plugin versions against vendor or Patchstack guidance because the provided metadata is limited.
Exploitation context
No CISA KEV listing is provided, and the supplied sources do not claim active exploitation. The CVSS vector indicates remote network reachability, no privileges required, high complexity, and user interaction required.
Researcher notes
The source bundle names versions through 6.5.0.1, while the Patchstack URL slug references 6.4.0.5; verify the advisory directly. No exploit details, proof-of-concept status, or fixed version are present in the provided data.
Mitigation direction
- Inventory WordPress sites for the wpDataTables plugin and installed versions.
- Check wpDataTables and Patchstack guidance for the fixed version or official workaround.
- Update the plugin when an official fixed release is identified.
- If no fix is available, consider disabling the plugin where business impact permits.
- Monitor vendor advisories for clarification on affected and fixed versions.
Validation and detection
- Confirm whether wpDataTables is installed on each WordPress site.
- Record the exact plugin version and compare it with <= 6.5.0.1.
- Review vendor and Patchstack advisories for remediation status.
- Check web logs for unusual requests involving wpDataTables endpoints.
- Validate remediation by confirming the installed version is no longer affected.

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
