CVE-2026-23991

go-tuf affected by client DoS via malformed server response

5.9 MediumFix available

go-tuf is a Go implementation of The Update Framework (TUF). Starting in version 2.0.0 and prior to version 2.3.1, if the TUF repository (or any of its mirrors) returns invalid TUF metadata JSON (valid JSON but not well formed TUF metadata), the client will panic during parsing, causing a denial of service. The panic happens before any signature is validated. This means that a compromised repository/mirror/cache can DoS clients without having access to any signing key. Version 2.3.1 fixes the issue. No known workarounds are available.

go-tuf affected by client DoS via malformed server response

Security Disclosure: Client DoS via malformed server response

Summary

If the TUF repository (or any of its mirrors) returns invalid TUF metadata JSON (valid JSON but not well formed TUF metadata), the client will panic during parsing, causing a DoS. The panic happens before any signature is validated. This means that a compromised repository/mirror/cache can DoS clients without having access to any signing key.

Impact

Client crashes upon receiving and parsing malformed TUF metadata. This can cause long running services to enter an restart/crash loop.

Workarounds

None currently.

Affected code

The metadata.checkType function did not properly type assert the (untrusted) input causing it to panic on malformed data.
