The system fails to invalidate existing access tokens associated with sub-organization users…
CVE-2025-0326 is a high-severity vulnerability in WSO2 Identity Server from WSO2, with a CVSS 3.1 base score of 7.4 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 7.0.0.85 as the first without the flaw, so updating WSO2 Identity Server to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update WSO2 Identity Server to 7.0.0.85 or a later version.
- Update WSO2 Carbon OAuth to 7.0.26.51 or a later version.
- Read the advisory on security.docs.wso2.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
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.
