CVE-2025-0326 — Improper Token Revocation in WSO2 Identity Server Allows Unauthorized Access

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.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.1% (30-day exploitation probability)+0

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (WSO2 Identity Server, WSO2 WSO2 Carbon OAuth).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes, errors and authentication anomalies.

Affected scope

Vendor, product and versions as the sources word them.
