CVE-2025-58894 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in PHP programs, specifically affecting the axiomthemes Good Mood WordPress theme versions up to 1.16. This vulnerability allows an attacker to exploit PHP Local File Inclusion (LFI) by manipulating the filename parameter used in include or require statements without proper validation or sanitization. The flaw arises because the theme's PHP code does not adequately restrict or validate input controlling which files are included, enabling attackers to specify arbitrary local files on the server. Exploiting this vulnerability can lead to unauthorized disclosure of sensitive server files such as configuration files, password files, or application source code, thereby compromising confidentiality. According to the CVSS 3.1 vector (8.2), the attack requires no privileges (PR:N), no user interaction (UI:N), and can be performed remotely over the network (AV:N). The impact is primarily on confidentiality (C:H), with limited impact on integrity (I:L) and no impact on availability (A:N). Although no public exploits have been reported yet, the vulnerability's nature and ease of exploitation make it a critical concern for affected installations. The vulnerability was reserved in September 2025 and published in December 2025, indicating recent discovery. The lack of available patches at the time of reporting necessitates immediate mitigation efforts by administrators. This vulnerability is particularly relevant for websites using the Good Mood theme, which is popular among WordPress users for creating visually appealing sites. Attackers could leverage this flaw to gain insights into server configurations or escalate attacks by combining it with other vulnerabilities.

For European organizations, the primary impact of CVE-2025-58894 is the potential exposure of sensitive information stored on web servers running the vulnerable Good Mood theme. This can include database credentials, API keys, internal configuration files, or user data, leading to confidentiality breaches. Such data leaks can facilitate further attacks, including privilege escalation, lateral movement, or targeted phishing campaigns. Organizations in sectors handling sensitive personal data, such as finance, healthcare, or government, face increased regulatory and reputational risks under GDPR if data confidentiality is compromised. The vulnerability does not directly allow remote code execution or denial of service, but the information disclosure alone can have severe consequences. Since exploitation requires no authentication or user interaction, attackers can scan and target vulnerable websites en masse, increasing the likelihood of widespread compromise. The lack of known exploits in the wild currently provides a window for proactive defense, but the high CVSS score indicates that once exploited, the impact could be significant. European organizations relying on WordPress themes from axiomthemes should assess their exposure and prioritize remediation to prevent data breaches.

1. Apply patches or updates from axiomthemes as soon as they become available to address the vulnerability directly. 2. If patches are not yet available, implement strict input validation and sanitization on any parameters controlling file inclusion in the theme's PHP code, restricting inputs to a whitelist of allowed files or directories. 3. Employ web application firewalls (WAFs) configured to detect and block suspicious requests attempting to exploit file inclusion vulnerabilities, such as those containing directory traversal sequences or unusual file paths. 4. Restrict PHP configuration settings to disable remote file inclusion (allow_url_include=Off) and limit file system access permissions to minimize the impact of any file inclusion attempts. 5. Conduct regular security audits and code reviews of custom themes and plugins to identify similar vulnerabilities. 6. Monitor web server logs for unusual access patterns or attempts to include local files. 7. Educate web administrators and developers about secure coding practices related to file inclusion and input validation. 8. Consider isolating vulnerable web applications in segmented network zones to limit lateral movement if compromised.
