CVE-2017-16857 (GCVE-0-2017-16857)

Vulnerability from cvelistv5 – Published: 2017-12-05 16:00 – Updated: 2024-09-17 02:01

Summary

It is possible to bypass the bitbucket auto-unapprove plugin via minimal brute-force because it is relying on asynchronous events on the back-end. This allows an attacker to merge any code into unsuspecting repositories. This affects all versions of the auto-unapprove plugin, however since the auto-unapprove plugin is not bundled with Bitbucket Server it does not affect any particular version of Bitbucket.

Severity

No CVSS data available.
