CVE-2026-55221: CWE-532: Insertion of Sensitive Information into Log File in malach-it boruta-server
Description
Boruta is a standalone authorization server that aims to implement OAuth 2.0 and Openid Connect up to decentralized identity specifications. Prior to version 0.10.0, Boruta logged sensitive OAuth and OpenID Connect values in business event logs. Logged values could include access tokens, refresh tokens, authorization codes, agent tokens, direct-post codes, ID tokens, VP tokens, and tokens submitted to introspection or revocation endpoints. An attacker with access to Boruta logs, log aggregation systems, or the administration log viewer could recover these credentials and use them until expiration or revocation. This issue has been patched in version 0.10.0.

Technical Analysis
CVE-2026-55221 describes a vulnerability in malach-it's boruta-server where sensitive OAuth 2.0 and OpenID Connect tokens and codes were inserted into business event logs prior to version 0.10.0. These logged values include access tokens, refresh tokens, authorization codes, agent tokens, direct-post codes, ID tokens, VP tokens, and tokens submitted to introspection or revocation endpoints. An attacker with access to these logs or log viewing systems could extract these credentials and use them until they expire or are revoked. The issue is classified under CWE-532 (Insertion of Sensitive Information into Log File).
Potential Impact
Exposure of sensitive OAuth and OpenID Connect tokens in logs can lead to unauthorized access if an attacker obtains these logs or has access to log aggregation or administration tools. The attacker could impersonate users or services until the tokens expire or are revoked. This compromises confidentiality and integrity of authentication and authorization processes but does not affect availability.
Mitigation Recommendations
This vulnerability has been patched in boruta-server version 0.10.0. Users should upgrade to version 0.10.0 or later to prevent sensitive token information from being logged. No other mitigation or temporary workaround is indicated.
