CVE-2026-60018
Gitea OneDev migration denial of service
Description
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-compatible server returning an oversized or never-ending response. This can consume memory and hold migration workers, impairing service availability.
