CVE-2026-1182Public exploitNetwork attack vector

Confidential issue-title disclosure via unredacted nested reference

Published Mar 12, 2026 · Updated Mar 12, 2026

Information disclosure in affected GitLab CE/EE versions allows remote authenticated users to read confidential issue titles. The Banzai abstract reference filter retains nested link HTML in link_content_html and fails to redact a confidential issue reference before rendering a merge request comment. Exploitation requires an authenticated account, a public victim project with restricted or confidential issues, and a crafted nested link; exposure is limited to issue titles.
