FS Poster could let attackers insert malicious database commands

CVE-2025-26978 · published 1 year ago
Summary

The FS Poster plugin for WordPress lets users create social media posts, but it does not properly check input before sending commands to the database. An attacker could craft special data that changes the database query, potentially reading or altering stored information. Update FS Poster to version 6.5.9 or later, or apply the vendor's patch, to stop this risk.
