What happened

Summary

The password reset flow did not revoke existing refresh tokens, allowing an attacker with a previously stolen refresh token to continue minting valid JWTs after the victim resets their password.

Details

passwordReset() in users.service.ts updated token_version (invalidating JWTs) but did not call UserRefreshToken.deleteAllUserToken(). The refreshToken() method only checked token existence, not token_version. Both passwordChange() and signOut() correctly deleted all refresh tokens.

Impact

An attacker who previously obtained a refresh token retains access after password reset until the token expires.

About this data

This record was ingested from a data source. Retrieved: Nov 6, 2026, 00:35 UTC. Ingestion is not an independent editorial investigation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.
