CVE-2025-12658 is a stored cross-site scripting vulnerability in the Preload Current Images plugin for WordPress, affecting all versions up to and including 1.3. The issue is due to improper neutralization of input in the 'complete' parameter of the 'preload_progress_bar' shortcode, allowing authenticated contributors or higher to inject arbitrary scripts. This vulnerability can lead to script execution in the context of users visiting the compromised pages, potentially impacting confidentiality and integrity of user sessions. The CVSS 3.1 base score is 6.4 with vector AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N, indicating network attack vector, low attack complexity, requiring privileges, no user interaction, scope changed, and low confidentiality and integrity impact without availability impact.

An attacker with contributor-level or higher privileges can inject persistent malicious scripts into pages via the vulnerable shortcode parameter. These scripts execute in the browsers of users who access the infected pages, potentially leading to session hijacking, data theft, or other client-side impacts. The vulnerability does not affect availability. The scope is changed, meaning the vulnerability affects resources beyond the attacker’s privileges. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the Preload Current Images plugin if possible. Monitor official channels for updates or patches from the plugin developer.
