CVE-2026-71189
LowCVSS 3.5Summary
An attacker can construct a request that, if issued by another application user, will cause JavaScript code supplied by the attacker to execute within the user's browser in the context of that user's session with the application. This is a classic cross-site scripting (XSS) vulnerability.
Risk Assessment
Enables an attacker to execute arbitrary JavaScript in the victim's session, potentially leading to session cookie theft, account takeover, or data modification. This may compromise the confidentiality and integrity of user data.
Recommendation
Implement proper output encoding and input validation to prevent script injection. Consider deploying a Content Security Policy (CSP) and updating the application to a patched version.
Other vulnerabilities in Web Application
See all- CVE-2026-71302High
The application accepts user-supplied session identifiers and does not regenerate the session ID after authentication. This allows an attacker to predefine a session ID and reuse it after victim authentication, resulting in session takeover.
- CVE-2026-69662Low
The application uses unsafe functions that allow execution of inline scripts and string evaluation functions. This may lead to execution of untrusted JavaScript code.
- CVE-2026-48999Medium
Attackers inject malicious scripts (e.g., JavaScript) into the target system. When other users visit infected pages, the scripts execute in their browsers, enabling cookie theft, session hijacking, and content tampering.
- CVE-2025-41716Medium
The web application allows an unauthenticated remote attacker to learn information about existing user accounts with their corresponding role due to missing authentication for critical function.
