A fix is referenced (a reference tagged "Patch", often a source commit), but no release containing it is confirmed — find the release that contains it; until it is applied, mitigate (WAF / firewall / segmentation).

The WP Ultimate CSV Importer plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 7.9.8 via the '->cus2' parameter. This allows authenticated attackers with author-level permissions or above, if the administrator previously grants access in the plugin settings, to create a PHP file and execute code on the server. The author resolved this vulnerability by removing the ability for authors and editors to import files, please note that this means php file creation is still allowed for site administrators, use the plugin with caution.

CISA SSVC: Track at low or medium mission impact; Track* at high (mission-essential systems).
Action: A fix is referenced, but no release containing it is confirmed. Check the referenced fix and the vendor's advisory for a release that contains it and apply that within your standard update timelines; until then, restrict network exposure of the affected system or apply the vendor's mitigation.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
