Deeper analysis

CVE-2025-58891 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, also known as 'PHP Remote File Inclusion,' that enables PHP Local File Inclusion in the Sanger WordPress theme developed by AncoraThemes. This flaw affects all versions of the Sanger theme up to and including 1.24.0, with no lower bound specified.

The vulnerability has a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating it is exploitable remotely over the network by unauthenticated attackers with no privileges required and no user interaction needed, though it demands high attack complexity. Successful exploitation allows attackers to achieve high impacts on confidentiality, integrity, and availability, potentially enabling unauthorized access to local files on the server.

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
attack.mitre.org →
T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
attack.mitre.org →
Why these techniques?

T1190 directly matches exploitation of a public-facing WordPress theme vulnerability (PHP LFI). T1005 is facilitated by unauthorized remote access to and reading of local files on the server.
