Deeper analysis
CVE-2025-15283 is a stored cross-site scripting (XSS) vulnerability, classified under CWE-79, in the Name Directory plugin for WordPress. It affects all versions up to and including 1.30.3 and stems from insufficient input sanitization and output escaping of the 'name_directory_name' and 'name_directory_description' parameters. This allows arbitrary web scripts to be injected into pages, with the vulnerability published on 2026-01-14 and assigned a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N).
Unauthenticated attackers can exploit the vulnerability remotely with low complexity and no privileges or user interaction required. By submitting malicious payloads via the affected parameters, they can store scripts on the target site that execute in the context of any user's browser when accessing the injected page, enabling potential theft of session data or further site compromise through changed scope impacts.
Advisories reference code fixes in the plugin's changeset at https://plugins.trac.wordpress.org/changeset/3438261/, addressing vulnerable lines in admin.php (marks 927-928) and shortcode.php (marks 38, 41, 69).

Directly requires validation and sanitization of untrusted inputs such as the name_directory_name and name_directory_description parameters before they are stored or processed.
Requires filtering or encoding of information outputs to prevent execution of injected scripts in rendered pages, addressing the missing output escaping.
Provides integrity verification mechanisms that can detect unauthorized script insertions or modifications resulting from the stored XSS payload.
