CVE-2025-69090: 
WordPress vulnerability analysis and mitigation

CVE-2025-69090 is a PHP Local File Inclusion (LFI) vulnerability in the Remons WordPress theme developed by ovatheme. The flaw stems from improper control of filename parameters used in PHP include/require statements (CWE-98), allowing unauthenticated remote attackers to include and execute arbitrary PHP files. All versions of the Remons theme through 1.3.4 are affected. The vulnerability was published on March 5, 2026, and assigned by Patchstack. It carries a CVSS v3.1 base score of 8.1 (High) (Feedly, Patchstack).

The root cause is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program), where user-supplied input is passed unsanitized to PHP's include or require constructs within the Remons theme. An unauthenticated attacker can craft a network request that manipulates the filename parameter to point to arbitrary local PHP files on the server, causing them to be included and executed in the context of the web application. Exploitation requires high attack complexity (e.g., specific preconditions such as file upload capability or knowledge of file paths), but no privileges or user interaction are needed. No public proof-of-concept code has been identified at this time (Feedly, Patchstack).

Successful exploitation could allow an attacker to read sensitive files on the server (e.g., WordPress configuration files containing database credentials), execute arbitrary PHP code, and achieve full system compromise. The CVSS assessment rates confidentiality, integrity, and availability impacts all as High, meaning an attacker could exfiltrate sensitive data, modify site content or server files, and disrupt service availability. Lateral movement within the hosting environment is also a risk if database credentials or other secrets are exposed through included files (Feedly).

As of the time of reporting, there is no known public proof-of-concept exploit and no evidence of active in-the-wild exploitation. The EPSS score is approximately 0.053%, indicating a low current probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been reported (Feedly).

1. Reconnaissance: Identify WordPress sites using the Remons theme (version ≤ 1.3.4) via passive techniques such as HTTP response headers, theme directory paths (e.g., /wp-content/themes/remons/), or tools like WPScan.
2. Identify vulnerable parameter: Analyze the theme's PHP source code or observed HTTP requests to locate the parameter passed to a PHP include or require statement without proper sanitization.
3. Craft malicious request: Construct an HTTP request that supplies a manipulated filename value pointing to a sensitive local file (e.g., ../../../../wp-config.php) or a previously uploaded malicious PHP file.
4. Trigger file inclusion: Submit the crafted request to the vulnerable endpoint; if successful, the server includes and executes the specified file, returning its contents or executing attacker-controlled code.
5. Achieve objective: Depending on the included file, the attacker may read database credentials from wp-config.php, execute a web shell for persistent access, or escalate privileges within the hosting environment (Feedly, Patchstack).

• Network: Unusual HTTP GET or POST requests to theme-related endpoints (e.g., /wp-content/themes/remons/) containing path traversal sequences such as ../, ..%2F, or encoded variants in query parameters.
• Logs: WordPress or web server access logs showing requests with file path manipulation patterns targeting the Remons theme; HTTP 200 responses to requests containing traversal sequences.
• File System: Unexpected PHP files or web shells uploaded to writable directories (e.g., /wp-content/uploads/); modification timestamps on core WordPress files that do not align with legitimate updates.
• Process: Unusual child processes spawned by the web server process (e.g., bash, curl, wget) that may indicate post-exploitation activity following successful code execution.

No patched version of the Remons theme has been confirmed as available at the time of reporting. Site administrators should immediately consider deactivating and removing the Remons theme (versions ≤ 1.3.4) until an official patch is released. As interim mitigations, deploying a Web Application Firewall (WAF) with rules to block path traversal and file inclusion patterns is recommended. Monitor web server and WordPress access logs for suspicious file inclusion attempts. Follow the Patchstack advisory for updates on patch availability (Patchstack, Feedly).

The vulnerability was noted in the Wordfence Intelligence Weekly WordPress Vulnerability Report for the week of March 2–8, 2026, indicating it was captured in routine WordPress security monitoring (Wordfence). VulDB also indexed the vulnerability shortly after disclosure. No significant broader media coverage or notable researcher commentary has been identified beyond standard vulnerability database entries.
