CVE-2026-2725: Improper Authorization in Gerrit allowing Code Review Bypass via "Submitted Together"
Incorrect authorization in the "submitted together" feature in Gerrit versions 2.12 and later allows an authenticated attacker with force push permissions on a secondary branch to bypass code review and forcefully submit code to restricted branches via a crafted submission matching the "topic" tag of an unapproved change.
Security readout for executives and security teams
Plain-English summary
CVE-2026-2725 is an authorization flaw in Gerrit code review. An authenticated user with force-push rights on a secondary branch could bypass review controls and submit code to restricted branches through the “submitted together” feature. This affects source-code integrity rather than availability or confidentiality.
Executive priority
Treat as a medium-priority source-code integrity risk. Prioritize environments hosting critical code or broad developer permissions. Immediate focus should be permission review and vendor guidance tracking.
Technical view
Gerrit 2.12 and later are described as affected. The flaw is CWE-863 improper authorization in “submitted together,” involving crafted submission behavior tied to a matching topic tag. CVSS v4.0 is 6.0, with low attack complexity, low privileges required, and high integrity impact.
Likely exposure
Organizations running Gerrit 2.12 or later are potentially exposed, especially where users have force-push permissions on secondary branches and workflows use topics or submitted-together changes.
Exploitation context
Sources do not report active exploitation, and the CVE is not marked KEV. Abuse requires authenticated access and specific repository permissions, limiting broad internet-scale exposure but increasing insider or compromised-account risk.
Researcher notes
Public detail is limited to the CVE description and Gerrit issue reference. No patch version or exploit evidence is provided in the supplied sources. Avoid assuming impact beyond Gerrit’s authorization and code-review bypass scenario.
Mitigation direction
Check Gerrit vendor guidance and issue 486131256 for fixed versions or official workarounds.
Review and minimize force-push permissions, especially on secondary branches.
Audit topic-based and submitted-together workflows for restricted branch protections.
Monitor recent restricted-branch submissions for unexpected topic-linked changes.
Validation and detection
Inventory Gerrit instances and confirm version exposure against vendor guidance.
Review project permissions for users or groups with force-push rights.
Check whether submitted-together and topic workflows are used on protected repositories.
Audit recent merged changes to restricted branches for unusual topic relationships.

CWE-863: Authorization and privilege behavior lookup
Authorization weaknesses can support privilege escalation and valid-account review, depending on exploit path. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Incorrect Authorization
Incorrect Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
