CVE-2025-58791 describes a stored cross-site scripting vulnerability in the Arjan Olsder SEO Auto Linker plugin (versions up to 1.5.3). The issue is caused by improper neutralization of input during web page generation, which allows attackers with high privileges to inject malicious scripts that are stored and later executed in the context of other users. The vulnerability has a CVSS 3.1 score of 5.9, reflecting medium severity with network attack vector, low attack complexity, required privileges, and user interaction. No patch or official remediation guidance is currently available, and the product is not a cloud service, so remediation depends on vendor updates.

Successful exploitation of this vulnerability could allow an attacker with high privileges to inject malicious scripts that execute in the browsers of users viewing affected pages. This can lead to partial compromise of confidentiality, integrity, and availability of the affected system or user data. However, exploitation requires user interaction and elevated privileges, limiting the ease of attack. No known exploits are currently reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should restrict administrative access to trusted personnel and be cautious with user input handling. Monitor vendor channels for updates and apply patches promptly once available.
