When Gitea's built-in SSH server is enabled (`START_SSH_SERVER = true`), the presented public key was looked up with an SQL `LIKE` comparison of its encoded content, which is case-insensitive on some databases, including the default SQLite. An attacker who can construct a case variant of another user's registered RSA public key for which they can derive the private key could have that key matched to the victim's account and authenticate over SSH as that user. Keys are now looked up by fingerprint.

Gitea's container registry served blob downloads with a `Content-Type` taken from the media type declared in pushed image manifests, without a `Content-Disposition` or restrictive content security policy. A user who can push container images can publish a blob containing HTML and JavaScript with a `text/html` media type. When a victim who is authenticated to the instance opens the blob URL in a browser, the script runs on the Gitea origin and can perform actions as the victim, such as creating API tokens.

When a Gitea Actions run was inserted, older runs in the same workflow-level concurrency group were cancelled without checking whether the new run still needed approval. Because fork pull request runs are inserted under the base repository, a user who can open a pull request from a fork could cancel trusted in-progress runs that share a concurrency group with `cancel-in-progress` enabled, without approval and without running any code. On self-hosted runners this can interrupt deployments and leave partial state behind.

When `[migrations] ALLOWED_DOMAINS` was configured, a hostname matching the allow list was accepted without checking its resolved address against the local-network restrictions. A user who can start repository migrations and control the DNS of an allowed hostname could make it resolve to loopback or private addresses and bypass `ALLOW_LOCALNETWORKS = false`, reaching internal services from the Gitea server. Instances without `ALLOWED_DOMAINS` configured are not affected by this specific bypass.

Gitea's repository migration and pull mirror egress checks could be bypassed with a hostname that returns multiple DNS answers, because the address that was validated was not necessarily the address Git later connected to. A low-privileged user who can create migrations or mirrors could direct the server to internal services, reading from and writing to reachable internal Git or HTTP endpoints. Content from internal responses could additionally be disclosed through migration and mirror error messages.
