Deeper analysis
CVE-2025-26548 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the kdmurray Random Image Selector plugin (random-image-selector) for WordPress. This flaw affects all versions of the plugin from n/a through 2.4 inclusive. The vulnerability was published on 2025-03-15 and carries a CVSS v3.1 base score of 7.1.
An unauthenticated attacker with network access can exploit this vulnerability by crafting malicious input that is reflected back in the web page without proper neutralization. Exploitation requires low complexity and user interaction, such as tricking a victim (e.g., a site administrator) into visiting a malicious URL. Successful exploitation executes arbitrary JavaScript in the victim's browser context with changed scope, resulting in low impacts to confidentiality, integrity, and availability, such as potential session hijacking or data theft.
The Patchstack advisory provides details on this vulnerability, including specifics for affected versions like 1.5.6, and recommends mitigation steps such as updating the plugin.
