CVE-2026-24137

sigstore legacy TUF client allows for arbitrary file writes with target cache path traversal

5.8 MediumFix available

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 signed target metadata; however, it does not validate that the resulting path stays within the cache base directory. A malicious TUF repository can trigger arbitrary file overwriting, limited to the permissions that the calling process has. Note that this should only affect clients that are directly using the TUF client in sigstore/sigstore or are using an older version of Cosign. Public Sigstore deployment users are unaffected, as TUF metadata is validated by a quorum of trusted collaborators. This issue has been fixed in version 1.10.4. As a workaround, users can disable disk caching for the legacy client by setting SIGSTORE_NO_CACHE=true in the environment, migrate to https://github.com/sigstore/sigstore-go/tree/main/pkg/tuf, or upgrade to the latest sigstore/sigstore release.

sigstore legacy TUF client allows for arbitrary file writes with target cache path traversal

Summary

The legacy TUF client pkg/tuf/client.go, which supports caching target files to disk, constructs a filesystem path by joining a cache base directory with a target name sourced from signed target metadata, but it does not validate that the resulting path stays within the cache base directory.

Note that this should only affect clients that are directly using the TUF client in sigstore/sigstore or are using an older version of Cosign. As this TUF client implementation is deprecated, users should migrate to https://github.com/sigstore/sigstore-go/tree/main/pkg/tuf as soon as possible.

Note that this does not affect users of the public Sigstore deployment, where TUF metadata is validated by a quorum of trusted collaborators.

Impact

A malicious TUF repository can trigger arbitrary file overwriting, limited to the permissions that the calling process has.

Workarounds

Users can disable disk caching for the legacy client by setting SIGSTORE_NO_CACHE=true in the environment, migrate to https://github.com/sigstore/sigstore-go/tree/main/pkg/tuf, or upgrade to the latest sigstore/sigstore release.

Fix HTML parser misimplementation of a part of the HTML specification for table related tags (CVE-2025-58190, GO-2026-4441, bsc#1258048).
Fix issue where the HTML parser takes a very long time or even never returns (CVE-2025-47911, GO-2026-4440, bsc#1258047).
Update ot 1.4.5
- Fix for moderate severity GO-2025-4176 / CVE-2025-65105 / GHSA-j3rw-fx6g-q46j (bsc#1255462): Ineffective application of selinux / apparmor --security option. Updates of a few dependent go libraries for related security fixes.
- Other fix Run FUSE processes in a separate process group. This detaches them from the main process so they don't receive signals such as interrupts sent to a terminal there. This was not a problem with interactive shells because they start their own group, but was a problem with some programs with interactive Read/Eval/Print/Loops such as python. An interrupt there would kill the FUSE processes.
From 1.4.4
- By applying patches to the bundled fuse2fs, allow again the possibility of using a non-writable ext3 image file as an overlay. Fixes regression introduced in 1.4.3.
- If an overlay or bound data image is asked to be mounted writable but the user has no write access to the image, show a warning message instead of silently switching to readonly.
- Avoid a fatal error when starting fakeroot from suid mode while in an NFS directory.
- Fix 32-bit builds which were accidentally broken by a library upgrade that was done for a minor security issue.
Fix CVEs:
- GO-2025-4135 - CVE-2025-47914 Malformed constraint may cause denial of service in golang.org/x/crypto/ssh/agent.

No need for binutils-gold for aarch64
Update to 1.4.3
- Corrected the mconfig -s option for statically building apptainer and starter binaries.
- Resolved an issue where the Makefile generated by mconfig -b failed when the build directory was not a subdirectory of the Apptainer source code.
- Fixed %files in definition files to correctly copy symlinks pointing above the destination directory but within the destination stage root filesystem.
- Addressed a typo in nvliblist.conf ( libnvoptix.so.1 was corrected to libnvoptix.so).
- Prevented timeouts during cleanup after building gocryptfs-encrypted SIF files.

- Resolved a hang when copying files between build stages while using suid mode without user namespaces.
- Fixed issues with running and building containers of different architectures than the host via binfmt_misc when using rootless fakeroot.

Changes for apptainer:

Update apptainer to version v1.5.1

Work around segmentation fault sometimes seen while mksquashfs under proot is creating a SIF file.
Update bundled PRoot to version 5.4.0-rootless.3 in order to fix a problem where SIF files could be corrupted when mksquashfs died with a signal. The proot command was not passing back an error exit code.
Updated bundled squashfuse_ll to version 0.6.2 in order to fix a crash sometimes seen with apptainer in unprivileged docker.
Update bundled fuse2fs to version 1.47.4 instead of patching the bugs in 1.47.3.
Fix a crash that happened when /etc/resolv.conf was a symlink while building from a definition file using the localimage bootstrap.
Support hosts that have an /etc/resolv.conf symlink pointing to ../run in addition to /run.
Change the download-dependencies script to skip downloading the PRoot source code on architectures that it is known to not support (that is: ppc*, s390*, and riscv*). In those situations Apptainer will skip trying to compile and run proot. As a result original owners and groups of files will not be preserved in SIF images built by unprivileged users, as was the case for all architectures prior to 1.5.0.
Fix panic encountered during progress bar update while pulling image.
Fix fakeroot overwriting root's username in /etc/passwd with the host user's name, a regression introduced in v1.5.0.
Add nonested flag for --mount specifications to prevent individual bind mounts from being passed to nested containers via APPTAINER_BIND.
