Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache CXF's cxf-rt-rs-security-oauth2 module, versions 4.2.0 up to 4.2.2 and below 4.1.7, writes the clientId request parameter into OAuth2 server warning logs without removing control characters. An attacker who can send requests to the OAuth2 endpoint can inject arbitrary content, including fake log entries, into the server logs. Upgrade to version 4.2.2 or 4.1.7.
