AI Analysis
Technical Summary
CVE-2026-18361 is a stored cross-site scripting vulnerability in the IRIS web application (iris-web) version 2.4.26. The flaw arises from improper neutralization of input during web page generation in the datastore upload function, allowing an attacker with low privileges and requiring user interaction to inject and execute malicious scripts. The vulnerability has a CVSS 3.1 base score of 7.6, reflecting network attack vector, low attack complexity, low privileges required, and user interaction needed, with high confidentiality impact and limited integrity impact. No official fix or patch is currently documented.
Potential Impact
Successful exploitation can lead to the execution of arbitrary scripts in the context of other users, potentially exposing sensitive information (high confidentiality impact) and limited integrity impact. The vulnerability does not affect availability. Attackers require low privileges and user interaction to exploit this vulnerability remotely over the network.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the datastore upload function to trusted users only and consider implementing additional input validation or output encoding as a temporary mitigation. Monitor vendor communications for updates on patches or official mitigations.
