The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

No authentication is required (PR:N), but the attack has high complexity (AC:H) due to the need for precise file path knowledge and server conditions that allow file inclusion (e.g., log pollution, accessible temporary files). The theme must process attacker-controlled input in a file-include context-likely an endpoint that accepts a filename parameter without sanitization. Exploitation is not possible under default hardened configurations unless specific PHP settings or application logic permit injection.

Impact

CVSS 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) reflects high impact but high attack complexity, reducing real-world risk. EPSS score of 0.08% (23rd percentile) indicates low exploitation likelihood, consistent with no active exploitation (absent from CISA KEV) and no known public exploit. Under SSVC, the vulnerability is unattested and not automatable due to AC:H. Overall, this is a moderate priority: patch when feasible, not an emergent threat.

Exploit ScenarioDerived

An unauthenticated attacker sends a crafted HTTP request to a vulnerable WordPress site, injecting path traversal sequences to force the theme’s include function to load a predictable log file containing malicious PHP code. If successful, the attacker executes arbitrary commands on the server. No public exploit code is available at this time.

AnalysisAIv1 – Jul 26, 2026

Local file inclusion in the Fabric WordPress theme (≤1.5.0) allows unauthenticated attackers to include arbitrary PHP files, leading to potential remote code execution or sensitive data exposure. Exploitation requires high attack complexity, and no public exploit or active exploitation (KEV) has been reported, with EPSS indicating a 0.08% probability of widespread use.

RemediationAI

Upgrade the Fabric theme to a version beyond 1.5.0; the exact fix version is likely listed in the Patchstack advisory. If a patch is unavailable, disable the theme until remediation. As a compensating control, deploy a WAF rule to block directory traversal and file inclusion patterns targeting the theme's URL endpoints-this may introduce false positives. Restricting server file permissions and disabling dangerous PHP functions (e.g., allow_url_include) reduces impact but does not eliminate the vulnerability.

Technical ContextAI · show details

The vulnerability is a PHP Local File Inclusion (CWE-98) in the Fabric theme for WordPress. Improper validation of user-controlled input passed to include/require statements allows an attacker to specify a local file path, potentially loading malicious PHP code from server files like logs or temporary uploads. The CPE cpe:2.3:a:axiomthemes:fabric:*:*:*:*:*:wordpress:*:* confirms the affected component is the WordPress theme. Successful exploitation can escalate to RCE if file content is attacker-controllable.

Attack Technique

Local File Inclusion vulnerabilities occur when an application accepts user-controlled input to specify which file should be loaded or executed, typically through functions like PHP's `include()`, `require()`, or `fopen()`.

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
