## Description

XWiki is an open-source wiki software platform. From 16.7.0 to 16.10.11, 17.4.4, or 17.7.0, in an instance which is using the XWiki Jetty package (XJetty), a context is exposed to statically access any file located in the webapp/ folder. It allows accessing files which might contains credentials. Fixed in 16.10.11, 17.4.4, and 17.7.0.

## CrowdSec analysis

[CVE-2025-55749](https://euvd.enisa.europa.eu/vulnerability/CVE-2025-55749) is a high-severity vulnerability in XWiki's Jetty package (XJetty) that allows unauthenticated attackers to statically access any file within the webapp/ directory, including files that may contain sensitive credentials. This flaw could be exploited remotely to steal confidential information, potentially leading to further compromise of the affected XWiki instance.

CrowdSec has been tracking this vulnerability and its exploits since 7th of January 2026.

According to CrowdSec data, while opportunistic exploitation dominates, a portion of threat actors trying to exploit CVE-2025-55749 apply basic targeting methods such as port or service detection. This indicates emerging patterns of selective targeting.
CrowdSec data also reveals a clear uptick in attacks involving CVE-2025-55749 over the past week. Activity is above the usual baseline, suggesting growing attention from attackers. This may reflect rising awareness, recent exploit releases, or expanded targeting efforts.

Attackers exploit this vulnerability by sending requests to URLs containing `/webapps/xwiki/WEB-INF/xwiki.properties` to access sensitive configuration files within the XWiki web application. This targets deployments using the XJetty package and can lead to information disclosure.
