CVE-2025-1783 is a stored cross-site scripting vulnerability in the Gallery Styles WordPress plugin (versions up to 1.3.4). It results from improper neutralization of input during web page generation (CWE-79), allowing authenticated users with Contributor-level privileges or higher to inject arbitrary web scripts via the Gallery Block. These scripts execute in the context of users viewing the injected pages, potentially leading to information disclosure or session manipulation. The vulnerability has a CVSS 3.1 base score of 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, and partial confidentiality and integrity impact.

An attacker with Contributor-level or higher access can inject malicious scripts that execute in the browsers of users viewing the compromised pages. This can lead to partial confidentiality and integrity impacts, such as theft of user data or manipulation of page content. There is no impact on availability. No known exploits have been reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Contributor-level access to trusted users only and consider disabling or removing the Gallery Styles plugin if possible to prevent exploitation.
