Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-613.
Summary
WSO2 Identity Server from 7.0.0 before 7.0.0.85 and WSO2 Carbon OAuth from 7.0.26 before 7.0.26.51 are affected. The system does not invalidate existing access tokens of sub-organization users during password reset, role change or sub-organization disablement (CWE-613). A remote attacker without privileges can use previously issued tokens that remain active and have been exposed to them, under high attack complexity.

Description from the CNA
The system fails to invalidate existing access tokens associated with sub-organization users during sensitive account management operations such as password reset, role change, or sub-organization disablement. This oversight allows previously issued tokens to remain active even after the user's access context has been modified or revoked through administrative actions. The identified issue could lead to unauthorized access by a malicious actor, but only when all of the following conditions are met: previously issued access tokens remain active, and these tokens have been exposed to malicious actors.
