EchelonGraph scoreLOW confidence

This medium-severity CVE scores 4.3 under CISA-ADP (Vulnrichment) CVSS v3.1 (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

With [migrations] ALLOWED_DOMAINS set to a matching entry such as * or a hostname wildcard, Gitea's migration URL validation could permit reserved and link-local addresses, such as 169.254.169.254, even when ALLOW_LOCALNETWORKS = false. The local-network block list did not cover these ranges, and a hostname matching the allow list was accepted regardless of its resolved address. A user who can start migrations on such an instance could reach these addresses from the Gitea server; the default empty ALLOWED_DOMAINS configuration is not affected.
