    CVE-2026-71184

    Gitea fork workflow approval bypass through review events

    Gitea's pull request review notifier does not attach the pull request to the Actions notification, so the fork workflow approval gate does not recognize the run as originating from a fork. Review comment and review approval or rejection events can consequentl…

    CVE-2026-66877

    Gitea fork workflow approval bypass through concurrency cancellation

    Gitea enforces first-time fork contributor approval by blocking jobs, but some job transition and dispatch paths do not re-check the run's approval requirement. A separate run sharing a job-level concurrency group can cancel a pending job and cause its blocke…

    CVE-2026-60010

    Gitea organization team policy bypass through repository API

    Gitea's repository-side team-link API allows a repository administrator who is not an organization owner to attach organization teams to a repository despite RepoAdminChangeTeamAccess being disabled. The endpoint does not enforce the organization's restrictio…

    CVE-2026-60018

    Gitea OneDev migration denial of service

    Gitea's OneDev migration downloader reads the entire remote version response into memory without a size limit and uses a client without a timeout. An authenticated user who can start a repository migration can direct it to an attacker-controlled OneDev-compat…

    CVE-2026-60021

    Gitea GitLab migration denial of service

    Gitea's initial GitLab migration version probe uses an HTTP client without a timeout and does not attach the migration task's cancellation context. An authenticated user who can start migrations can target an attacker-controlled server that keeps the response…

    CVE-2026-62925

    Gitea Alpine package parsing memory exhaustion

    Gitea parses Alpine package uploads before enforcing package-size quotas and does not bound the decompressed .PKGINFO data or its dependency and provides entry counts. An authenticated user with package-publish permission can upload a small, highly compressed…

    CVE-2026-63021

    Gitea Swift package manifest memory exhaustion

    Gitea's Swift package parser limits each manifest to 128 KiB but does not limit the number of manifests or their aggregate size before reading them into memory. An authenticated user with package-publish permission can upload a highly compressed archive conta…

    CVE-2026-66874

    Gitea required Actions check bypass through skipped workflows

    For pull request events, Gitea reads workflow definitions from the pull request head and posts a synthetic skipped status when workflow branch or path filters exclude execution. A fork pull request author can supply a workflow matching a required status conte…

    CVE-2026-70406

    Gitea private comparison disclosure with public-only tokens

    Gitea's shared comparison helper omits the token repository-access check used when updating pull requests. A public-only token with read:repository scope can route a comparison or pull request creation through a public base repository and retrieve commit hist…

    CVE-2026-78433

    Gitea private attachment disclosure through repository mismatch

    Gitea's web attachment handler skips its cross-repository ownership check for attachments created before 16 January 2026 and checks permissions against the repository named in the request URL instead. An unauthenticated attacker who knows a private attachment…

    CVE-2026-70402

    Gitea local code execution through writable Git hooks

    Gitea creates server-side Git hook directories and scripts with mode 0777 and relies on the process umask to restrict access. With a permissive umask such as 0000 or 0002, another local user who can reach the repository storage may modify a hook or add an exe…

    CVE-2026-70396

    Gitea organization repository creation token scope bypass

    Gitea's organization repository-creation API requires write:organization but omits the write:repository token scope enforced by other repository-creation routes. A personal access token or OAuth application token without repository-write scope can therefore c…

    CVE-2026-73135

    Gitea hidden-owner repository listing disclosure

    Gitea restricted-user issue search disclosure

    Gitea restricted-user SSH and GPG key metadata disclosure

    Gitea organization listing token scope bypass

    Gitea private workflow badge token scope bypass

    Gitea repository initialization resource exhaustion

    Gitea does not limit the length of the gitignores field accepted by repository-creation forms and the API. Repository initialization splits the field into template names, repeatedly reads the referenced templates, and buffers their contents in memory. An atta…
