CVE-2025-51990 Details
XWiki through version 17.3.0 is affected by multiple stored Cross-Site Scripting (XSS) vulnerabilities in the Administration interface, specifically under the Presentation section of the Global Preferences panel. An authenticated administrator can inject arbitrary JavaScript payloads into the HTTP Meta Info, Footer Copyright, and Footer Version fields. These inputs are stored and subsequently rendered without proper output encoding or sanitization on public-facing pages. As a result, the injected scripts are persistently executed in the browser context of any visitor to the affected instances including both authenticated and unauthenticated users. No user interaction is required beyond visiting a page that includes the malicious content. Successful exploitation can lead to session hijacking, credential theft, unauthorized actions via session riding, or further compromise of the application through client-side attacks. The vulnerability introduces significant risk in any deployment, especially in shared or internet-facing environments where administrator credentials may be compromised.

Exploit prediction scoring system (EPSS) score for CVE-2025-51990
EPSS (Exploit Prediction Scoring System): EPSS predicts the likelihood that a vulnerability will be exploited in the wild. A higher percentage means a greater chance of an exploit occurring. The EPSS model produces a probability score between 0 and 1 (0 and 100%).
0.04 Probability of exploitation activity being observed over the next 30 days (11th percentile)
CVSS score for CVE-2025-51990
CVSS (Common Vulnerability Scoring System): An open framework owned and managed by FIRST.Org, Inc. that assigns a numerical score from 0 to 10 to software vulnerabilities to indicate their severity.

Bitsight Data Discovery and Continuous Threat Scanning

Bitsight, the leading provider in Cyber Risk Management, introduced the next-generation internet scanner Bitsight Groma in May 2024. This technology continuously scans the entire internet to discover assets, collect asset attribution evidence, and identify an ever-growing set of security observations, such as vulnerabilities and misconfigurations. Groma’s scanning activities presently encompass:


  • 40 million-plus monitored organizations
  • 250 million-plus host names
  • 4 billion-plus routable IPv4 and IPv6 addresses

Greynoise’s recent study testifies the speed of Bitsight Groma.
