CVE-2025-68063: Splash WordPress Theme Local File Inclusion (LFI) Vulnerability – HIGH Risk

Technical summary

CVE-2025-68063 is a Local File Inclusion (LFI) vulnerability classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program) affecting Splash theme versions up to 4.4.3. The vulnerability permits an authenticated contributor to manipulate file inclusion mechanisms within the theme, enabling arbitrary local file access on the server. The attack requires network access and valid contributor credentials but no elevated privileges or user interaction. The CVSS 3.1 score of 7.5 (HIGH) reflects the combination of high confidentiality and integrity impact with network accessibility constrained by authentication and complexity factors.

Business impact

Organizations running WordPress sites with the Splash theme face potential exposure of sensitive server-side data including database credentials, configuration files, and application secrets. A compromised or malicious contributor account could extract information enabling lateral movement, privilege escalation, or further compromise. For sports clubs and membership-based organizations, this could lead to exposure of member data, payment information, or administrative credentials—triggering regulatory compliance concerns (GDPR, payment card standards) and reputational damage.

Affected systems

The vulnerability affects Splash - Sport Club WordPress Theme for Basketball, Football, Hockey in all versions up to and including 4.4.3. This theme is specifically designed for sports organization websites. Any WordPress installation running this theme at vulnerable versions is affected if contributor-level users exist (a common configuration for content managers, coaches, or administrative staff).

Exploitability

Exploitation requires valid WordPress contributor credentials and network access to the site—a moderate barrier that eliminates opportunistic external attacks but creates material risk from insider threats or compromised user accounts. The attack requires some technical knowledge to craft file inclusion payloads, but no zero-click or user-interaction components increase complexity. The accessibility via authenticated HTTP requests makes this practically exploitable once credentials are obtained.

Remediation

Update the Splash theme to a patched version released after 4.4.3. Verify the patch version directly from the theme vendor's official repository or advisory. Additionally, audit contributor-level user accounts for legitimacy and review file access logs for suspicious include requests. Implement Web Application Firewall (WAF) rules to block file inclusion patterns in theme requests as a compensating control pending patching.

Patch guidance

Check the official Splash theme repository (WordPress.org theme directory or vendor site) for the latest available version and release notes confirming this CVE is addressed. Apply the update through the WordPress dashboard admin panel or via your hosting control panel. Test the update in a staging environment first to ensure compatibility with plugins and customizations. Review the changelog to confirm the patch addresses CWE-98 local file inclusion vectors in the theme's include/require handlers.

Detection guidance

Monitor WordPress error logs for warnings related to failed file includes or path traversal attempts within theme directories. Search web server access logs for suspicious GET/POST parameters targeting theme files (e.g., requests with '../' sequences or file paths in query strings to Splash theme endpoints). Implement security plugins that log file inclusion attempts by contributors. Audit wp-content/themes/splash/ for any modified files suggesting post-exploitation activity. Consider WAF rules that detect and block LFI payloads in HTTP requests to theme resources.

Why prioritize this

While the vulnerability requires contributor access (reducing external threat surface), the HIGH CVSS score of 7.5 reflects significant confidentiality and integrity impact. For organizations managing contributor accounts loosely or in shared hosting environments where account compromise is plausible, this warrants expedited patching—typically within 2-4 weeks. Sports clubs with memberships or payment processing should prioritize even higher due to sensitivity of stored data.

Risk score, explained

The CVSS 3.1 score of 7.5 combines network attack vector with low attack complexity but mandatory login requirement (AV:N/AC:H/PR:L). High confidentiality impact (reading sensitive files) and high integrity impact (potential file manipulation or information exfiltration) drive the severity. The attack does not impact availability, and scope remains unchanged. This positions the vulnerability as HIGH priority but not CRITICAL, reflecting real but bounded exploitation scenarios.
