CVE-2025-7059 is a stored cross-site scripting vulnerability in the Simple Featured Image WordPress plugin by jdegayojr, affecting all versions up to 1.3.1. The vulnerability exists because the plugin fails to properly sanitize and escape input received via the 'slideshow' parameter, allowing authenticated users with Contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute when any user accesses the compromised page, potentially leading to unauthorized actions or data exposure. The CVSS 3.1 base score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial confidentiality and integrity impact.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the 'slideshow' parameter. When other users view these pages, the scripts execute in their browsers, potentially leading to unauthorized actions or data disclosure. The vulnerability impacts confidentiality and integrity but does not affect availability. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or removing the Simple Featured Image plugin if feasible. Monitor for updates from the vendor regarding patches or official mitigations.
