CVE-2020-10978Public exploitNetwork attack vector

Private issue metadata disclosure via stale move references

Published Apr 8, 2020 · Updated Aug 4, 2024

Information disclosure in GitLab CE and EE 8.11 through 12.9 allows remote attackers to read private-project issue metadata. Moved-issue system notes and GraphQL discussion output retain and render destination references without enforcing the destination project's visibility. A publicly visible source issue must be moved into a private project; exposed data includes the private namespace, issue title, and issue number.
