CVE-2025-58899 is a vulnerability classified as PHP Local File Inclusion (LFI) found in the AncoraThemes Frame product, affecting versions up to 2.4.0. The root cause is improper control over the filename parameter used in PHP include or require statements, which allows an attacker to manipulate the input to include arbitrary files from the local filesystem. This can lead to execution of malicious code, disclosure of sensitive files, or further exploitation such as privilege escalation or remote code execution if combined with other vulnerabilities. The vulnerability arises because the application fails to properly sanitize or validate user-supplied input that determines which files are included during runtime. Although no public exploits are currently known, the vulnerability is critical in nature due to the common use of PHP in web applications and the widespread deployment of AncoraThemes products in WordPress environments. The lack of a CVSS score indicates this is a newly published vulnerability, and no official patches or mitigations have been released yet. Attackers exploiting this flaw could gain unauthorized access to server files, potentially compromising the entire web server environment. The vulnerability is particularly dangerous because file inclusion issues can be exploited without authentication and often require minimal user interaction, increasing the attack surface. AncoraThemes Frame is a popular theme framework used in many WordPress sites, which are prevalent in Europe, increasing the likelihood of targeted attacks in this region.

For European organizations, exploitation of CVE-2025-58899 could result in severe consequences including unauthorized disclosure of sensitive data, server compromise, and potential lateral movement within networks. Confidentiality is at risk as attackers may read configuration files, credentials, or other sensitive information stored on the server. Integrity can be compromised if attackers execute arbitrary code or modify files, potentially defacing websites or implanting backdoors. Availability may also be affected if attackers disrupt web services or cause application crashes. Organizations relying on AncoraThemes Frame for their web presence, especially those in sectors like finance, healthcare, and government, could face reputational damage, regulatory penalties under GDPR, and operational disruptions. The absence of known exploits currently provides a window for proactive mitigation, but the ease of exploitation and the critical nature of PHP LFI vulnerabilities mean that the threat should be treated with urgency.

1. Monitor AncoraThemes and Patchstack advisories closely for official patches or updates addressing CVE-2025-58899 and apply them promptly. 2. In the interim, implement strict input validation and sanitization on all parameters that influence file inclusion, ensuring only allowed filenames or paths can be processed. 3. Employ web application firewalls (WAFs) with rules designed to detect and block suspicious file inclusion attempts targeting PHP applications. 4. Restrict PHP include paths using configuration directives such as open_basedir to limit accessible directories. 5. Conduct thorough code reviews of customizations or plugins that interact with AncoraThemes Frame to identify and remediate unsafe include/require usage. 6. Harden server configurations by disabling unnecessary PHP functions and ensuring least privilege access to web server files. 7. Regularly audit logs for unusual file access patterns or errors indicative of exploitation attempts. 8. Educate development and security teams about secure coding practices related to file inclusion vulnerabilities.
