CVE-2026-13201 Kubevirt: virt-handler-rhel9: kubevirt: safepath symlink following in virt-handler enables notify socket hijacking and node-level vm disruption

A flaw was found in KubeVirt's safepath package used by virt-handler. The OpenAtNoFollow function uses OPATH|ONOFOLLOW to obtain a file descriptor to a path leaf, but downstream operations resolve the path via /proc/self/fd/N using link-following syscalls. When the leaf is a symlink, the kernel...

CVE-2026-13201

CVE-2026-13201 concerns KubeVirt’s safepath package, where OpenAtNoFollow uses O_PATH|O_NOFOLLOW to obtain a descriptor for a path leaf, but downstream helpers access paths via /proc/self/fd/N. If the leaf is a symlink, the kernel dereferences it, bypassing intended no-follow protection. An attac...

CVE-2026-52811 Gogs: UploadRepoFiles writes outside repo working tree via committed parent sym

Gogs is an open source self-hosted Git service. Prior to 0.14.3, Repository.UploadRepoFiles checks for symlinks only on the leaf of the upload target osx.IsSymlinktargetPath. The siblings UpdateRepoFile, DeleteRepoFile, and GetDiffPreview use hasSymlinkInPath, which lstats every component —...

CVE-2026-52811

CVE-2026-52811 (Gogs) : In versions 0.14.0–0.14.2, UploadRepoFiles checks for symlinks only on the leaf path, while other code paths validate the entire path. An attacker with repo-write access can upload a file whose filename contains a backslash, which path normalization converts to a multi-seg...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Before versions 7.1.2-16 and 6.9.13-41, authorization based on the "domain=" path was checked before the final file could be opened or used. A symlink swap was used to bypass the policy-denied read/writ...

Astra Linux – Vulnerability in busybox

A flaw was discovered in BusyBox. This vulnerability allows an attacker to modify files outside of the intended extraction directory by creating a malicious tar archive containing unvalidated hardlink or symlink entries. If the tar archive is extracted with elevated privileges, this flaw can lead...

postgresql: PostgreSQL: Operating system account hijack via symlink following in pg_basebackup and pg_rewind

A flaw was found in PostgreSQL. This vulnerability, related to symlink following in pgbasebackup plain format and pgrewind, allows an origin superuser to overwrite local files. By exploiting this, an attacker could potentially hijack the operating system account. This attack has practical...
