CVE-2026-7195: Progress Sitefinity Information Disclosure

CVE-2026-7195 Overview

CVE-2026-7195 is an improper input validation vulnerability [CWE-20] affecting web services in Progress Sitefinity. The flaw allows a remote unauthenticated attacker to compromise the integrity and confidentiality of user accounts. Successful exploitation requires user interaction and a non-default site configuration. The vulnerability spans multiple Sitefinity release branches, including versions 14.1.x through 14.3.x, and earlier builds of 14.4.x, 15.0.x, 15.1.x, 15.2.x, 15.3.x, and 15.4.x. Progress has issued fixed builds across each supported branch.

Critical Impact

Remote unauthenticated attackers can compromise the integrity and confidentiality of Sitefinity user accounts when a vulnerable, non-default configuration is in use.

Affected Products

• Progress Sitefinity 14.1.x through 14.3.x (all builds)
• Progress Sitefinity 14.4.x before 14.4.8152, 15.0.x before 15.0.8234, and 15.1.x before 15.1.8335
• Progress Sitefinity 15.2.x before 15.2.8441, 15.3.x before 15.3.8531, and 15.4.x before 15.4.8630

Technical Details for CVE-2026-7195

Vulnerability Analysis

The vulnerability resides in Sitefinity web services that fail to properly validate input from remote clients. An unauthenticated attacker can craft requests targeting these endpoints to manipulate account-related operations. Because the issue affects confidentiality and integrity of user accounts, successful exploitation can lead to account takeover or unauthorized disclosure of account data. The attack is launched over the network and does not require prior credentials, but the targeted user must interact with attacker-supplied content, and the site must run a non-default configuration that exposes the affected behavior.

Root Cause

The root cause is improper input validation [CWE-20] in one or more Sitefinity web service handlers. The affected code paths accept request parameters without enforcing the constraints required to safely process account-impacting actions. As a result, malformed or attacker-controlled values reach logic that should only operate on validated, trusted input.

Attack Vector

Exploitation is performed remotely over HTTP/HTTPS against the Sitefinity application. The attacker delivers a crafted link or page that triggers a request to a vulnerable web service when a victim interacts with it. When the targeted site runs the qualifying non-default configuration, the request succeeds and modifies or exposes account data. No code examples are published by the vendor. Refer to the Progress Security Advisory for technical guidance.

Detection Methods for CVE-2026-7195

Indicators of Compromise

• Unexpected modifications to user account attributes such as email, password reset tokens, or role assignments without corresponding administrative activity.
• Web service requests to Sitefinity account or user management endpoints originating from external referrers or unusual user-agent strings.
• Spikes in failed or anomalous responses from Sitefinity web service endpoints in IIS or application logs.

Detection Strategies

• Inventory all Sitefinity deployments and identify instances running versions in the affected range, prioritizing internet-facing sites.
• Review configuration against the vendor advisory to determine whether the non-default setting required for exploitation is enabled.
• Correlate web access logs with authentication events to identify account changes that follow unauthenticated web service calls.

Monitoring Recommendations

• Forward IIS and Sitefinity application logs to a centralized analytics platform and alert on anomalous request patterns to account-related endpoints.
• Monitor for sudden changes in account state, including password resets, email updates, and role escalations, paired with external request sources.
• Track outbound links and referrers delivered to users in support, marketing, or CMS workflows that could be abused to satisfy the user interaction requirement.

How to Mitigate CVE-2026-7195

Immediate Actions Required

• Upgrade Sitefinity to a fixed build: 14.4.8152, 15.0.8234, 15.1.8335, 15.2.8441, 15.3.8531, or 15.4.8630 or later on the matching branch.
• For sites still on 14.1.x through 14.3.x, plan an upgrade to a supported, patched branch as no fix is listed for those minor versions.
• Audit Sitefinity configuration for the non-default setting referenced in the vendor advisory and disable it where the patched build cannot be deployed immediately.

Patch Information

Progress has released security updates across all supported Sitefinity branches. Refer to the Progress Security Advisory for CVE-2026-7195 for branch-specific fixed versions and upgrade instructions.

Workarounds

• Revert any non-default configuration changes identified in the Progress advisory until patched builds are deployed.
• Restrict access to Sitefinity administrative and web service endpoints using network controls, WAF rules, or IP allow-listing.
• Educate administrators and content editors about the user interaction requirement and the risk of clicking untrusted links targeting Sitefinity sites.

# Example: restrict access to Sitefinity web service endpoints at the WAF or reverse proxy
# Replace placeholders with values appropriate to your environment
location ~* /(restapi|services)/ {
    allow 10.0.0.0/8;
    deny all;
}
