CyberRota Analysis
AI-GeneratedGerrit Code Review versions 2.16.0 through 3.14.2 are vulnerable to an incorrect authorization flaw that allows both authenticated and potentially unauthenticated users to access private repository content and restore revoked administrative privileges through specially crafted requests. This vulnerability arises from improper handling of project name normalization and cache eviction logic, which can lead to unauthorized disclosure of sensitive data. Organizations using affected versions should prioritize patching to versions 3.12.10, 3.13.9, or 3.14.3 to mitigate the risk of data exposure and privilege escalation.
Original NVD Description
Incorrect Authorization (CWE-863) in project name normalization (ProjectUtil.stripGitSuffix) and ProjectCache eviction logic (ProjectCacheImpl) in Gerrit Code Review versions 2.16.0 through 3.12.9, 3.13.0 through 3.13.8, and 3.14.0 through 3.14.2 allows an authenticated user (or an unauthenticated user if the repository was previously public) to cause unauthorized disclosure of private repository content and durable restoration of revoked project-owner administrative privileges via crafted requests using repeated .git suffixes (such as project.git.git) across REST APIs, Gitiles, or SSH Git commands. Because Gerrit strips only a single terminal .git suffix when constructing the logical ProjectCache key while JGit (FileKey.lenient) resolves the suffixed alias to the same canonical bare repository on disk, revoking read access or removing owner rules on the canonical project name fails to evict the cached alias ProjectState during the cache validity window, enabling reads of newly created private commits or writes to refs/meta/config. This issue is fixed in Gerrit Code Review versions 3.12.10, 3.13.9, and 3.14.3.
