Summary

In all versions of GitLab CE/EE since version 8.0, an attacker can set the pipeline schedules to be active in a project export so when an unsuspecting owner imports that project, pipelines are active by default on that project. Under specialized conditions, this may lead to information disclosure if the project is imported from an untrusted source.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Enhance with deb and rpm package type records.
