CVE-2025-6024 — Cross-Site Scripting via Authentication Endpoint in Multiple WSO2 Products Allows Redirection to Malicious Websites

The authentication endpoint fails to encode user-supplied input before rendering it in the web page, allowing for script injection. An attacker can leverage this by injecting malicious scripts into the authentication endpoint. This can result in the user's browser being redirected to a malicious website, manipulation of the web page's user interface, or the retrieval of information from the browser. However, session hijacking is not possible due to the httpOnly flag protecting session-related cookies.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.2% (30-day exploitation probability)+2
  • Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (WSO2 Api Manager, WSO2 Identity Server).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  4. Exploitation requires user interaction: tighten email/web filtering and warn affected users.
  5. Search available logs for exploit probes matching the vulnerability class (cross-site scripting), errors and authentication anomalies.

What should defenders know first?

CVE-2025-6024 is "Cross-Site Scripting via Authentication Endpoint in Multiple WSO2 Products Allows Redirection to Malicious Websites", rated Medium. It affects Api Manager (WSO2); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.1 describes technical severity. EPSS 0.23% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
