CVE-2026-2813: CWE‑601: URL Redirection to Untrusted Site (Open Redirect) in Esri ArcGIS Server
CVE-2026-2813 is an open redirect vulnerability in Esri ArcGIS Server version 11.5. It arises from insufficient input validation in the login redirection workflow, allowing an authenticated attacker to craft requests that redirect users to untrusted sites. The impact is limited to confidentiality under specific user interactions and does not affect server-side components or other security boundaries. The vulnerability has a medium severity rating with a CVSS score of 4.7. No official patch or remediation guidance has been provided yet by the vendor.
AI Analysis
Technical Summary
ArcGIS Server 11.5 contains an input validation weakness in its login redirection logic, enabling authenticated attackers to cause the application to redirect browsers to unintended, potentially untrusted URLs. This open redirect vulnerability is confined to client-side navigation during authentication and does not compromise server-side components or cross-component security. The issue results in limited confidentiality impact contingent on user interaction.
Potential Impact
Successful exploitation may lead to users being redirected to untrusted external sites, potentially exposing them to phishing or other social engineering attacks. However, the vulnerability does not allow server-side compromise, data integrity loss, or availability impact. The confidentiality impact is limited and depends on user interaction with the malicious redirection.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with login redirections and verify URLs before following them. No official remediation or temporary fix has been published by Esri at this time.
