CVE-2025-5350 — SSRF and Reflected XSS Vulnerability in Deprecated Try-It Feature of Multiple WSO2 Products

SSRF and Reflected XSS Vulnerabilities exist in multiple WSO2 products within the deprecated Try-It feature, which was accessible only to administrative users. This feature accepted user-supplied URLs without proper validation, leading to server-side request forgery (SSRF). Additionally, the retrieved content was directly reflected in the HTTP response, enabling reflected cross-site scripting (XSS) in the admin user's browser context. By tricking an administrator into accessing a crafted link, an attacker could force the server to fetch malicious content and reflect it into the admin’s browser, leading to arbitrary JavaScript execution for UI manipulation or data exfiltration. While session cookies are protected with the HttpOnly flag, the XSS still poses a significant security risk. Furthermore, SSRF can be used by a privileged user to query internal services, potentially aiding in internal network enumeration if the target endpoints are reachable from the affected product.

Who exploits it and how urgent it is

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

How the score was calculated

Public exploit/PoC (nuclei)+4
EPSS 0.6% (30-day exploitation probability)+7
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.

Identify exposed assets running the affected vendor/product/version combinations (WSO2 Api Control Plane, WSO2 Api Manager, WSO2 Enterprise Integrator…).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Exploitation requires user interaction: tighten email/web filtering and warn affected users.
Search available logs for exploit probes matching the vulnerability class (cross-site scripting), errors and authentication anomalies.

What should defenders know first?

CVE-2025-5350 is "SSRF and Reflected XSS Vulnerability in Deprecated Try-It Feature of Multiple WSO2 Products", rated Medium. It affects Api Control Plane (WSO2); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 4.8 describes technical severity. EPSS 0.62% 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.
