Security readout for executives and security teams
Plain-English summary
CVE-2026-28118 affects the WordPress Welldone theme through version 2.4. It is a high-severity file inclusion issue that could let an unauthenticated attacker access or influence sensitive server-side files. Public sources do not state active exploitation or a named fixed version.
Executive priority
Prioritize identification this week for internet-facing WordPress sites. Treat confirmed Welldone <=2.4 installations as high-risk until vendor guidance or a safe replacement is confirmed.
Technical view
The issue is classified as CWE-98: improper control of filenames in PHP include/require logic. The CVSS 3.1 score is 8.1 with network attack vector, no privileges, no user interaction, high complexity, and high confidentiality, integrity, and availability impact. Sources describe PHP Local File Inclusion in axiomthemes Welldone <=2.4.
Likely exposure
Exposure is likely limited to WordPress sites with the axiomthemes Welldone theme installed at version 2.4 or earlier. Sites not using this theme are not indicated as affected by the provided sources.
Exploitation context
The CVE is not listed as CISA KEV, and the provided sources do not claim active exploitation. The vulnerability is remotely reachable and unauthenticated per CVSS, but exploitation is rated high complexity.
Researcher notes
Evidence is incomplete on remediation. The CVE description and Patchstack title identify Welldone <=2.4, while the structured affected data is sparse and internally unhelpful. No exploit details, fixed version, or active exploitation claim is provided in the source bundle.
Mitigation direction
- Inventory WordPress sites for the Welldone theme and record installed versions.
- If Welldone <=2.4 is present, check axiomthemes and Patchstack for vendor guidance.
- Remove or replace the theme if it is unused or no supported fix is available.
- Increase monitoring for suspicious requests targeting the Welldone theme path.
Validation and detection
- Confirm whether the Welldone theme is installed on each WordPress instance.
- Verify the installed theme version and compare it with the <=2.4 affected range.
- Review web server and WordPress logs for anomalous theme-related file access attempts.
- Track the CVE and Patchstack entry for updated remediation details.

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.
