Deeper analysis
CVE-2025-58888 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified as PHP Remote File Inclusion but enabling PHP Local File Inclusion (LFI), in the WordPress theme "The Flash" by AncoraThemes. The issue affects all versions of The Flash up to and including 1.15, stemming from inadequate validation of filenames in PHP include/require statements (CWE-98).
Remote unauthenticated attackers (AV:N/PR:N) can exploit this vulnerability over the network, though it requires high attack complexity (AC:H) and no user interaction (UI:N). Successful exploitation grants high-impact confidentiality, integrity, and availability effects (C:H/I:H/A:H) with unchanged scope (S:U), potentially allowing attackers to include and execute arbitrary local PHP files, leading to server-side code execution or sensitive data disclosure on affected WordPress sites.
Mitigation details are available in the Patchstack advisory at https://patchstack.com/database/Wordpress/Theme/theflash/vulnerability/wordpress-the-flash-theme-1-15-local-file-inclusion-vulnerability?_s_id=cve, which documents the LFI vulnerability specific to The Flash theme version 1.15.
