The vulnerability CVE-2025-49307 affects the Magazine3 WP Multilang plugin for WordPress, specifically versions up to 2.4.19. It arises from improper control over the filename used in PHP include or require statements, enabling PHP Local File Inclusion (LFI). This can allow an attacker with low privileges and no user interaction to execute arbitrary code or access sensitive files on the server. The CVSS 3.1 vector indicates network attack vector, high attack complexity, low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to local file inclusion, potentially allowing attackers to execute arbitrary PHP code, read sensitive files, or disrupt service. The impact is high across confidentiality, integrity, and availability, meaning attackers could fully compromise the affected system or application data.

No official patch or remediation guidance is currently available from the vendor. Users should closely monitor Magazine3's advisories or trusted security sources for updates. Until a fix is released, consider disabling or removing the WP Multilang plugin if feasible to reduce exposure. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
