Machine-written summary

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

The Bitbucket Branch Source Plugin (Maven org.jenkins-ci.plugins:cloudbees-bitbucket-branch-source) versions before 887.va, including 886.v44cf5e4ecec5 and earlier, can print the Bitbucket OAuth access token in the build log in some cases. The source does not say what access an attacker needs to read the logs. Upgrade to version 887.va or later, which no longer includes the token in the build log URL.
