CVE-2026-48885 is an unauthenticated Cross-Site Scripting (XSS) vulnerability in Groundhogg HollerBox affecting versions up to 2.3.10.1. The issue stems from improper input neutralization during web page generation, categorized under CWE-79. The vulnerability allows attackers to inject malicious scripts that can impact confidentiality, integrity, and availability, as reflected in its CVSS 3.1 score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L). No vendor advisory or patch information is currently available, and no known exploits have been reported.

Successful exploitation of this vulnerability could allow an unauthenticated attacker to execute arbitrary scripts in the context of the affected application, potentially leading to partial compromise of confidentiality, integrity, and availability of the system. The CVSS vector indicates that user interaction is required, but no privileges or authentication are needed, and the scope is changed, meaning the impact extends beyond the vulnerable component.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider restricting access to vulnerable versions and monitoring for suspicious activity related to XSS attacks. Avoid deploying affected versions in high-risk environments.
