CVE-2025-23807 is a medium-severity vulnerability affecting the Spiderpowa Embed PDF plugin, which allows for stored Cross-site Scripting (XSS). This vulnerability occurs due to improper neutralization of input during web page generation. An attacker can exploit this vulnerability to inject malicious scripts, which may be executed in the context of the user's browser.
The CVSS score assigned to this vulnerability is 6.5, indicating a moderate level of risk to organizations. The vulnerability affects versions of the Spiderpowa Embed PDF plugin up to and including 1.0. Organizations that utilize this plugin should take immediate action to address this vulnerability.
Risk to organizations includes the potential for unauthorized access to user data, which can lead to further exploitation. Attackers may leverage this vulnerability to deploy harmful scripts that could compromise user accounts or facilitate phishing attacks.
Organizations should prioritize patching immediately to reduce the risk associated with this vulnerability. The Spiderpowa Embed PDF plugin's status is currently deferred, emphasizing the need for vigilance in monitoring and remediation efforts.
Vulnerability Details
The vulnerability is identified as CWE-79, which pertains to improper neutralization of input during web page generation, leading to stored XSS attacks. It was published on January 16, 2025, and affects versions of Spiderpowa Embed PDF from n/a through 1.0.
Technical Analysis
The root cause of CVE-2025-23807 is the inadequate validation of user input when generating web pages. This vulnerability has a low attack complexity and requires low privileges, but does necessitate user interaction for exploitation.
The attack vector is network-based, as it can be exploited remotely by an attacker who tricks a user into visiting a malicious link or executing a crafted payload. The impacts on confidentiality, integrity, and availability are all classified as low, indicating that while the risk exists, it does not result in catastrophic outcomes.
Risk & Impact Analysis
The deployment of the Spiderpowa Embed PDF plugin exposes organizations to the risk of XSS attacks, which can compromise user data and lead to phishing exploits. The low complexity and required user interaction indicates that while the attack may not be trivial, it remains a feasible threat, especially in environments where users are less security-aware.
The EPSS score of 0.00335 places this vulnerability in a lower risk percentile. However, organizations must remain proactive in their security posture, especially given the potential for future exploitation.
