CVE-2025-12590 describes a Cross-Site Scripting (XSS) vulnerability within the YSlider plugin for WordPress. This flaw allows unauthenticated attackers to inject arbitrary web scripts, potentially compromising user data and website functionality. The vulnerability affects versions 0.0.0 through 1.1 and can be exploited through a forged request tricking an administrator. A fix is available via plugin update.
The primary impact of CVE-2025-12590 is the ability for an attacker to execute arbitrary JavaScript code within the context of a user's browser. This can lead to a variety of malicious actions, including session hijacking, defacement of the website, redirection to phishing sites, and theft of sensitive information such as login credentials or personal data. The vulnerability's reliance on a forged request means an attacker needs to convince an administrator to click a malicious link, making social engineering a key component of exploitation. Successful exploitation could severely damage a website's reputation and compromise user trust.
CVE-2025-12590 was publicly disclosed on 2025-11-11. While no public proof-of-concept (PoC) code has been widely released, the vulnerability's nature and the ease of crafting forged requests suggest a moderate risk of exploitation. It is not currently listed on CISA KEV. Active campaigns targeting WordPress plugins are common, so vigilance is advised.
