Security readout for executives and security teams
Plain-English summary
CVE-2026-27995 affects the WordPress Justitia theme by ThemeREX, versions up to and including 1.1.0. The flaw can let an unauthenticated remote attacker include local files through unsafe PHP include handling. Reported impact is high across confidentiality, integrity, and availability, but exploitation complexity is rated high.
Executive priority
Treat this as a high-priority WordPress exposure if your organization uses the Justitia theme. The business concern is potential compromise of website data or service integrity. First determine whether the theme is present; then follow vendor guidance or remove dependency if no supported fix is available.
Technical view
The CVE describes CWE-98: improper control of a filename used in PHP include/require logic, resulting in local file inclusion in Justitia <= 1.1.0. CVSS 3.1 is 8.1 with AV:N, AC:H, PR:N, UI:N, S:U, and high C/I/A impact. The source bundle does not name a fixed version.
Likely exposure
Exposure is limited to WordPress sites using the ThemeREX Justitia theme at version 1.1.0 or earlier. The CVE data has some version-field inconsistency, so confirm installed theme name and version directly in WordPress or asset records.
Exploitation context
No CISA KEV listing is indicated, and the provided sources do not state active exploitation. The vulnerability is remotely reachable without authentication or user interaction, but CVSS rates attack complexity as high, meaning reliable exploitation likely depends on additional conditions.
Researcher notes
Evidence is limited to CVE and Patchstack-style advisory metadata. The affected range is described as through <= 1.1.0, while the structured affected version entry is sparse. Do not assume exploit availability or a patched version from the provided data. Validate with vendor advisory updates before closure.
Mitigation direction
- Identify all WordPress sites using the Justitia theme.
- Check ThemeREX and Patchstack guidance for a fixed version or workaround.
- Update the theme if a vendor-supported fixed release is available.
- If no fix is available, consider replacing or disabling the theme after business review.
- Prioritize internet-facing WordPress sites and sites with sensitive data.
Validation and detection
- Confirm whether the Justitia theme is installed and active.
- Record the installed theme version and compare it with <= 1.1.0.
- Review vendor and Patchstack advisories for updated remediation status.
- Check security monitoring for unusual file-access or PHP include-related errors.
- Document compensating controls if immediate remediation is not possible.

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.
