Answer in brief
CVE-2025-12627 records a Low severity (CVSS 2.4) vulnerability in Improper Refresh Token Implementation via User Impersonation Flow in WSO2 Identity Server Enables Continued Unauthorized Actions. The current sources do not mark it as known exploited. The current feed maps WSO2/WSO2 Carbon OAuth (generic), WSO2/WSO2 Identity Server (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 2.4. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

The user impersonation flow in WSO2 Identity Server fails to properly manage refresh tokens associated with impersonated sessions. This allows an attacker who has obtained an access token for an impersonated user to leverage the refresh token grant to obtain new access tokens, extending their ability to act as the legitimate user. An attacker who gains access to an impersonated user's access token can exploit this weakness to renew their authorization. This results in the continued ability to perform actions on behalf of the actual user, compromising log integrity and traceability by masking the true actor.
