CWE-367

Description

Improper enforcement of single-use authorization code semantics in the JPA OAuth2 authorization code grant provider in Apache CXFallows a remote attacker to obtain multiple valid access tokens from a single authorization code via concurrent token exchange requests that race the non-atomic find-then-delete operation against a shared relational database under READ_COMMITTED isolation. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fixes this issue.

Affected configurations

• apache cxf (< 3.6.13) • apache cxf (>= 4.0.0 < 4.1.9) • apache cxf (>= 4.2.0 < 4.2.4)
