AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Yoast Duplicate Post plugin versions through 4.6 are vulnerable to stored XSS when an administrator views a scheduled republish notice with a crafted title.
Vulnerability
The Yoast Duplicate Post plugin, versions through 4.6, inserts an unescaped post title and permalink into the Classic Editor scheduled republish notice. This vulnerability exists because user-supplied input is not properly neutralized before being displayed in the notice. [2]
Exploitation
An attacker needs to have the ability to schedule a post to be republished. The attacker crafts a post title with malicious script. When an administrator views the scheduled republish notice in the Classic Editor, the script will execute. [2]
Impact
Successful exploitation allows an attacker to execute arbitrary script in the administrator's browser. This can lead to session hijacking, defacement, or further compromise of the WordPress site. The scope of the compromise is limited to the privileges of the administrator viewing the notice. [2]
Mitigation
Yoast Duplicate Post versions 4.7 and later have fixed this vulnerability. Users are advised to update to the latest version of the plugin. No workarounds are available. [2]
