CVE-2026-119545

Forgejo through 15.0.11, 16.0.0 through 16.0.7, and 17.0.0 through 17.0.1 contains an information disclosure vulnerability in the GetPublicKey API handler that lacks an ownership check on key lookups. Authenticated users with a read:user token or session can enumerate sequential key IDs to obtain titles, fingerprints and public key material of other users' SSH, deploy and principal keys.

Forgejo through 15.0.11, 16.0.0 through 16.0.7, and 17.0.0 through 17.0.1 contains a path traversal vulnerability in restore-repo that allows attackers to read files outside the dump directory via crafted asset paths. Attackers can supply a dump whose release.yml DownloadURL or PatchURL contains ../ sequences, importing files like app.ini as release attachments when an administrator restores it.

Forgejo before 16.0.4 allows remote code execution via a crafted template repository because template expansion on files in .forgejo/template is mishandled.

Forgejo before 13.0.2 allows attackers to write to unintended files, and possibly obtain server shell access, because of mishandling of out-of-repository symlink destinations for template repositories. This is also fixed for 11 LTS in 11.0.7 and later.

Forgejo 13.0.0 through 16.0.4, when "[federation] ENABLED = true" is set, has a spoofing issue affecting identity integrity but not allowing account takeover or content modification. It does not verify that the HTTP Signature on an incoming ActivityPub activity was produced by the key belonging to the actor named in the activity body. A remote attacker hosting a single valid ActivityPub actor and keypair can submit signature-valid activities attributed to any actor identity.

Forgejo before 16.0.4 allows use of restricted API tokens for unintended access to the "allow maintainer edit" feature.

Vulnerability in Forgejo up to 15.0.4 in the net.LookupIP function of is_migrate_allowed.go allows remote server-side request forgery (SSRF). The attack can be initiated remotely, and the exploit is public.

Forgejo before version 15.0.3 contains a stored cross-site scripting vulnerability that allows authenticated attackers to execute arbitrary JavaScript in other users' browsers by setting a full name containing an HTML payload and triggering an Actions run. When the DEFAULT_SHOW_FULL_NAME option is enabled, the run description is assembled server-side with the user's display name interpolated into an HTML string via a translation function that does not escape its arguments, and the frontend renders the result using a Vue v-html binding, causing script execution for any user who views the affected Actions run page.
