What is CVE-2026-60018?
CVE-2026-60018 is a medium-severity denial of service vulnerability in Gitea, published on 14 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
