Security readout for executives and security teams
Plain-English summary
CVE-2026-27047 affects the WordPress Curly Core plugin through version 2.1.6. It can allow an attacker to include local files through improper filename handling in PHP. The published CVSS score is 8.1, reflecting potential confidentiality, integrity, and availability impact if successfully exploited.
Executive priority
Treat this as a high-priority WordPress plugin issue for any site using Curly Core. Prioritize inventory first, because urgency depends on whether the plugin is present. No source-provided evidence confirms active exploitation or an available patch.
Technical view
The issue is categorized as CWE-98 in Mikado-Themes Curly Core. The CVE description calls it PHP Local File Inclusion, while the CWE label references include/require filename control. CVSS 3.1 is AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H, meaning remote, unauthenticated exploitation is modeled but with high attack complexity.
Likely exposure
Exposure is likely limited to WordPress sites running Mikado-Themes Curly Core plugin version 2.1.6 or earlier. The supplied data does not identify other affected products, bundled distributions, or a fixed version.
Exploitation context
The CVE is not listed as KEV in the supplied data, and no cited source states active exploitation. The CVSS vector indicates no authentication or user interaction is required, but attack complexity is high.
Researcher notes
Source evidence is limited. The record describes LFI, while the CWE title references PHP Remote File Inclusion terminology. Do not assume exploitability details beyond the CVSS vector. No patch version, proof of exploitation, or workaround is named in the supplied sources.
Mitigation direction
- Inventory WordPress sites for the Curly Core plugin and installed version.
- If running version 2.1.6 or earlier, check vendor or Patchstack guidance immediately.
- Disable or remove the plugin if it is not business-critical.
- Apply any vendor-confirmed fixed release when available and tested.
- Monitor web logs for unusual requests involving Curly Core plugin paths.
Validation and detection
- Confirm whether Curly Core is installed on each WordPress site.
- Record the plugin version and compare it against affected versions through 2.1.6.
- Check Patchstack and the CVE record for updated remediation details.
- Review web access logs for suspicious plugin-targeted requests.
- Verify compensating controls after any disablement, removal, or update.

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.
