CVE-2026-2445· NVD / CVE Program· CNA WSO2

Reflected Cross-Site Scripting via URL Parameter in Multiple WSO2 Products Enables UI Redirection and Modification

Noroxi assessment

Priority: Monitor (action score 24/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.25% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The affected product accepts user-supplied input within a URL parameter without enforcing expected sanitization or encoding before rendering it within the response. This condition allows for the injection of malicious JavaScript payloads. An attacker can leverage this vulnerability to cause the user's browser to redirect to a malicious website, modify the user interface of the webpage, or retrieve sensitive information from the browser. However, the impact is mitigated for session hijacking as all session-related sensitive cookies are protected by the httpOnly flag.

Limit the impact of XSS

This is a cross-site scripting (XSS) vulnerability. A well-configured Content-Security-Policy doesn't fix it, but greatly reduces its impact. Check your site's CSP and other security headers for free.
