CVE-2025-62759

Vulnerability

Overview The WordPress Series plugin by Justin Tadlock, versions through 2.0.1, contains a stored cross-site scripting (XSS) vulnerability. This issue arises from improper neutralization of user-supplied input during web page generation, enabling an attacker to inject arbitrary HTML and JavaScript into series-related fields [1].

Exploitation

Conditions Exploitation requires a privileged user, such as an administrator or editor, to be tricked into performing an action, like clicking a malicious link or submitting a crafted form [1]. Once triggered, the injected script is stored in the database and executed when other users visit affected pages.

Impact

Successful exploitation allows an attacker to execute malicious scripts in the context of the victim's browser. This could lead to session hijacking, website defacement, redirection to malicious sites, or distribution of malware [1].

Mitigation

Users should update the Series plugin to the latest version (>2.0.1) immediately. If an update is not possible, restricting access to privileged accounts and using a web application firewall may provide temporary protection [1].
