DescriptionCVE.org

A vulnerability was found in Forgejo up to 15.0.4. This issue affects the function net.LookupIP of the file services/migrations/allowlist/is_migrate_allowed.go of the component Repository Migration Handler. Performing a manipulation results in server-side request forgery. The attack can be initiated remotely. The exploit has been made public and could be used. The patch is named b313bb83f5ff22bcc0378e0e0ca7bbd58303f168. It is recommended to apply a patch to fix this issue. The project maintainer explains: "I don't intend to backport this to v15 or v16 as it is a breaking change."

AnalysisAI

Server-side request forgery in Forgejo up to 15.0.4 allows authenticated users to bypass the repository migration IP allowlist by manipulating net.LookupIP in the migration handler, causing the Forgejo server to issue requests to internal network resources that should be unreachable. The CVSS 4.0 vector confirms network-exploitable, low-privilege access with limited but real impact across confidentiality and integrity. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid authenticated user session on the target Forgejo instance (CVSS PR:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N) indicates a network-reachable path with no attack complexity beyond holding an authenticated user account - a meaningful but real prerequisite on most self-hosted instances. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation The primary fix is manual application of upstream commit b313bb83f5ff22bcc0378e0e0ca7bbd58303f168 available at https://codeberg.org/forgejo/forgejo/commit/b313bb83f5ff22bcc0378e0e0ca7bbd58303f168; administrators should monitor pull request #13490 (https://codeberg.org/forgejo/forgejo/pulls/13490) for a tagged release incorporating the fix, as no patched release version has been confirmed at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
