Kerentanan Time-of-check Time-of-use (TOCTOU) Race Condition pada apache cxf. Skor CVSS 3.1 7.4 (High) menurut CISA ADP.

Deskripsi (NVD)

A race condition in AbstractOAuthDataProvider allows concurrent requests using the same Refresh Token to bypass single-use semantics and generate multiple valid Access Tokens, when 'recycleRefreshTokens' is set to false. A leaked refresh token can be replayed concurrently by multiple attackers or threads. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue.
