FreshRSS is a self-hosted RSS feed aggregator. Prior to version 1.26.2, HTML is sanitized improperly inside the `` attribute, which leads to cross-site scripting (XSS) by loading an attackers UserJS inside `<script src>`. In order to execute the attack, the attacker needs to control one of the victims feeds and have an account on the FreshRSS instance that the victim is using. An attacker can gain access to the victims account by exploiting this vulnerability. If the victim is an admin it would be possible to delete all users (cause damage) or execute arbitrary code on the server by modifying the update URL using fetch() via the XSS. Version 1.26.2 contains a patch for the issue.</p> </div> </div> </div> </div> </div> </div> </div> <footer> <div class="container py-4 py-lg-10"> <hr> <div class="text-muted d-flex justify-content-between align-items-center pt-3" style="text-align: center;"> <p class="mb-10"><center>Copyright © 2026 eXtreme Hosting</center></p> <p class="mb-10"><center><a href="/gdpr/">Privacy Policy GDPR/AVG</a> | <a href="/algemene-voorwaarden/">Algemene voorwaarden</a></center></p> </div> </div> </footer> <script src="/template/assets/bootstrap/js/bootstrap.min.js"></script> <script src="/template/assets/js/startup-modern.js"></script> </body> </html><img style="display: none;" src="https://telemetry.extremehosting.nl/Analy/?api=0C44A78F-C43E-4700-990A-0F40CE4B4A51&dtt=1746954019&urr=https://extremehosting.nl/cve/cve-details/CVE-2025-32015" />
