SUSE CVE-2026-24137

sigstore framework is a common go library shared across sigstore services and clients. In versions 1.10.3 and below, the legacy TUF client pkg/tuf/client.go supports caching target files to disk. It constructs a filesystem path by joining a cache base directory with a target name sourced from...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via the TUF client. An attacker can overwrite arbitrary files on the filesystem by supplying crafted target metadata that causes path traversal outside the intended cache directory. Note: This is only exploitable if...
