CVE-2026-22338: WordPress EcoBlue theme <= 1.15 - Local File Inclusion vulnerability

Synopsis

A local file inclusion vulnerability affects the EcoBlue WordPress theme by ThemeREX in versions 1.15 and earlier. The flaw is reachable over the network without any authentication, though certain attack conditions must align for exploitation to succeed. A successful attacker can read arbitrary files from the server, tamper with application data, and potentially crash or fully compromise the affected WordPress installation. No upstream fix has been published yet; HarborGuard is tracking the advisory for patch availability.

HarborGuard Coverage

Exploit Conditions

• Network reachabilityRequired

  The vulnerable endpoint is exposed over the network, meaning an attacker must be able to reach the WordPress service via HTTP or HTTPS to trigger the inclusion flaw.

• AuthenticationNot required

  No account or session credential of any kind is needed; the flaw is exploitable by any unauthenticated HTTP request.

• Victim interactionNot required

  The attacker does not need to trick or involve any user; the exploit is delivered directly to the server.

• Attack complexityDetail

  Attack complexity is rated High, meaning exploitation is not condition-free and may require the attacker to account for specific server configurations, file path guessing, or other environmental factors that cannot always be pre-determined.

Blast Radius

• A successful attacker reads arbitrary files from the server filesystem, including WordPress configuration files that contain database credentials and secret keys.
• With access to database credentials, an attacker can modify or delete persisted database rows, altering site content, user accounts, and application state.
• The integrity and availability of the WordPress installation are both at risk; an attacker can corrupt theme or plugin files, causing service disruption or enabling persistent backdoor placement.
• Full confidentiality, integrity, and availability impact is confirmed by the CVSS scoring, meaning complete compromise of the affected host is within scope of a successful exploit chain.
