CVE-2025-58888 is a vulnerability classified as improper control of filename for include/require statements in the PHP program within the AncoraThemes The Flash WordPress theme, versions up to and including 1.15. This vulnerability manifests as a Local File Inclusion (LFI) flaw, where the application fails to properly validate or sanitize user-supplied input used in PHP include or require functions. Consequently, an unauthenticated attacker can manipulate the filename parameter to include arbitrary files from the server's filesystem. This can lead to unauthorized disclosure of sensitive files such as configuration files, password files, or application source code, compromising confidentiality. The CVSS v3.1 score of 8.2 reflects a high-severity rating, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is primarily on confidentiality (C:H), with limited integrity impact (I:L) and no availability impact (A:N). While no public exploits have been reported yet, the vulnerability's characteristics make it a prime target for exploitation once a proof-of-concept or exploit code becomes available. The vulnerability affects websites using the AncoraThemes The Flash theme, which is a popular WordPress theme, potentially exposing numerous websites to risk. The lack of a patch link indicates that a fix may not yet be available, emphasizing the need for immediate mitigation efforts. Attackers exploiting this vulnerability could read sensitive files, gather information for further attacks, or potentially escalate to remote code execution under certain conditions. The vulnerability is particularly critical because it requires no authentication or user interaction, allowing remote exploitation over the internet.

For European organizations, the impact of CVE-2025-58888 can be significant, especially for those relying on WordPress websites using the AncoraThemes The Flash theme. Successful exploitation could lead to unauthorized disclosure of sensitive data such as credentials, personal data, or proprietary information, violating GDPR and other data protection regulations. This could result in reputational damage, regulatory fines, and loss of customer trust. Additionally, information gathered through LFI could be leveraged for further attacks, including privilege escalation or remote code execution, potentially leading to website defacement, service disruption, or use of compromised sites as attack platforms. Organizations in sectors with high online presence such as e-commerce, government, healthcare, and finance are particularly at risk. The vulnerability's ease of exploitation and lack of required authentication increase the likelihood of automated scanning and mass exploitation attempts, raising the urgency for European entities to address this threat promptly.

1. Immediate action should be to monitor for updates from AncoraThemes and apply any patches as soon as they become available. 2. Until a patch is released, disable or remove the vulnerable theme from production environments if feasible. 3. Implement strict input validation and sanitization on any user-supplied parameters related to file inclusion to prevent manipulation. 4. Use web application firewalls (WAFs) configured with rules to detect and block attempts to exploit LFI vulnerabilities, such as suspicious include path patterns or directory traversal sequences. 5. Restrict PHP include paths using open_basedir directives to limit the directories from which files can be included. 6. Conduct regular security audits and vulnerability scans to detect the presence of this theme and assess exposure. 7. Educate web administrators about the risks of using outdated or unpatched themes and plugins. 8. Employ intrusion detection systems (IDS) to monitor for anomalous file access patterns indicative of exploitation attempts. 9. Backup website data regularly to enable quick recovery in case of compromise. 10. Consider migrating to alternative, actively maintained themes with better security track records if patching is delayed.
