CVE-2026-22587 Overview
CVE-2026-22587 is a stored cross-site scripting (XSS) vulnerability affecting Ideagen DevonWay. A remote, authenticated attacker can craft a malicious payload in the 'Reports' page that executes arbitrary JavaScript code when another user views the report. This type of vulnerability allows attackers to persist malicious scripts within the application, potentially compromising user sessions, stealing sensitive data, or performing unauthorized actions on behalf of victims.
Critical Impact
Authenticated attackers can inject persistent malicious scripts that execute in the context of other users' browsers, potentially leading to session hijacking, credential theft, and unauthorized actions within the DevonWay platform.
Affected Products
- Ideagen DevonWay versions prior to 2.62.4
- Ideagen DevonWay versions prior to 2.62 LTS

Technical Details for CVE-2026-22587
Vulnerability Analysis
This stored cross-site scripting vulnerability (CWE-79) exists in the Ideagen DevonWay application's Reports functionality. The vulnerability allows authenticated users to inject malicious JavaScript payloads that are stored persistently within the application. When other users access the affected report, the malicious script executes within their browser context, inheriting their session privileges and access rights.
The attack requires the attacker to have authenticated access to the DevonWay platform with sufficient permissions to create or modify reports. Once the payload is stored, it remains active until explicitly removed, making it particularly dangerous as it can affect multiple users over time without requiring continued attacker interaction.
Root Cause
The root cause of CVE-2026-22587 is insufficient input sanitization and output encoding in the Reports page functionality. User-supplied input is not properly validated or escaped before being stored in the database and subsequently rendered in other users' browsers. This allows specially crafted HTML and JavaScript content to be interpreted as executable code rather than being displayed as harmless text.
Attack Vector
The attack is conducted over the network by an authenticated user. The attacker creates or modifies a report within the DevonWay application, embedding malicious JavaScript code in vulnerable input fields. When other users navigate to view the compromised report, the stored payload executes in their browser session. This can be leveraged to steal session cookies, redirect users to malicious sites, modify page content, or perform actions as the victim user.
The vulnerability is exploitable through the application's web interface, requiring only standard browser access and valid user credentials. The payload persists across page loads and user sessions, maximizing the potential impact.
Detection Methods for CVE-2026-22587
Indicators of Compromise
- Unexpected JavaScript code or HTML tags present in report content or database fields
- Anomalous report modifications by users who typically don't edit reports
- Browser-based alerts or redirects occurring when users access the Reports page
- Session cookie theft indicators such as unauthorized access from new IP addresses
Detection Strategies
- Implement web application firewall (WAF) rules to detect common XSS patterns in HTTP requests
- Monitor application logs for suspicious characters or script tags in report-related requests
- Deploy Content Security Policy (CSP) headers to detect and block inline script execution
- Review report content periodically for unexpected HTML or JavaScript artifacts
Monitoring Recommendations
- Enable detailed logging for all report creation and modification activities
- Configure alerting for CSP violation reports that may indicate XSS attempts
- Monitor user session patterns for signs of session hijacking following report access
- Implement real-time scanning of user-generated content for malicious payloads
How to Mitigate CVE-2026-22587
Immediate Actions Required
- Upgrade Ideagen DevonWay to version 2.62.4 or 2.62 LTS immediately
- Audit existing reports for suspicious or malicious content
- Review user access logs for potential exploitation attempts
- Implement or strengthen Content Security Policy headers as a defense-in-depth measure
Patch Information
Ideagen has released security patches addressing this vulnerability in DevonWay versions 2.62.4 and 2.62 LTS. Organizations should prioritize updating to these fixed versions. For additional details, consult the CISA CSAF Document or the official CVE.org record.
Workarounds
- Restrict report creation and modification privileges to trusted users only until patching is complete
- Implement additional input validation at the web server or WAF level to filter potential XSS payloads
- Deploy strict Content Security Policy headers to prevent inline script execution
- Consider temporarily disabling user-generated report functionality if the risk is deemed unacceptable
