ciguard: discover_pipeline_files follows symlinks out of scan root

Summary The discoverpipelinefiles function in src/ciguard/discovery.py introduced in v0.8.0 and used by the MCP scanrepo tool shipped in v0.8.1 walks a directory tree following symlinks, with cycle protection via tracking visited resolved paths. An attacker who can plant a symlink in a directory...

CLSA-2026-1777879919 perl: Fix of CVE-2018-12015

CVE-2018-12015: Archive::Tar path traversal — remove existing block-device or out-of-CWD symlink targets before overwriting during extraction...

gix and gitoxide's symlinked .gitmodules are followed and parsed from outside of the repository

Summary attachments: pocs.zip When Repository::submodules loads submodule metadata, it prefers the worktree .gitmodules file if that path exists. In the current implementation, the path is read with std::fs::read, which follows symlinks. As a result, a repository can present a symlinked .gitmodul...

Name of the Vulnerable Software and Affected Versions ciguard versions 0.8.0 through 0.8.1 Description The discover pipeline files function in src/ciguard/discovery.py improperly handles symlinks when walking a directory tree. An attacker who can place a symlink in a directory being scanned can...

Kata Container has CopyFile Policy Subversion via Symlinks

Summary An oversight in the CopyFile policy and perhaps the CopyFile handler allows untrusted hosts to write to arbitrary locations inside the guest workload image. This can be used to overwrite binaries inside the guest and exfiltrate data from containers; even those running inside CVMs. Details...

Name of the Vulnerable Software and Affected Versions apko versions 0.14.8 through 1.2.4 Description A crafted .apk file can install a TypeSymlink tar entry with a target pointing outside the build root. Subsequent directory-creation or file-write entries in the same or later archive can traverse...

apko dirFS has a symlink-following path traversal that allows multiple entry points to escape the build root

A crafted .apk could install a TypeSymlink tar entry whose target pointed outside the build root, and a subsequent directory-creation or file-write entry in the same or later archive could traverse that symlink to reach host paths the build user could write to. The root cause was the sanitizePath...

GHSA-RH99-WC69-C255 Contras Affected by CopyFile Policy Subversion via Symlinks

Impact The Kata agent policies generated by the Contrast CLI had an issue in the CopyFile verification, which allowed arbitrary writes to the guest root filesytem. A malicious process on the host with the capability to connect to the Kata agent VSOCK could connect to the agent and issue a series ...

golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root

A flaw was found in the internal/syscall/unix package in the Go standard library. If the target of the Root.Chmod function is replaced with a symbolic link during execution, specifically after Root.Chmod checks the target but before acting, the chmod operation will be performed on the file the...

JLSEC-2026-213 When sed is invoked with both -i (in-place edit) and --follow-symlinks, the function...

When sed is invoked with both -i in-place edit and --follow-symlinks, the function opennextfile performs two separate, non-atomic filesystem operations on the same path: 1. resolves symlink to its target and stores the resolved path for determining when output is written, 2. opens the original...

sed: GNU sed TOCTOU race condition

A Time-of-Check Time-of-Use TOCTOU race condition was found in GNU sed. When the -i in-place and --follow-symlinks options are used together, sed resolves the symlink but reopens the path for writing. An attacker with write access to the directory containing the symlink can swap it between the...

SUSE-SU-2026:21455-1 Security update for openCryptoki

This update for openCryptoki fixes the following issues: - CVE-2026-23893: use of symlinks in group-writable token directories can lead to privilege escalation and data exposure bsc1257116. - CVE-2026-40253: malformed BER-encoded cryptographic objects can lead to information disclosure and denial...

RUSTSEC-2026-0113 `unpack_in` can chmod arbitrary directories by following symlinks

In versions 0.6.0 and earlier of astral-tokio-tar, the unpackin API could inadvertently modify the permissions of external i.e. non-archive directories outside of the archive. An attacker could use this to contrite a tar archive that maliciously changes directory permissions outside of its intend...
