CVE-2026-19429

CVE-2026-19429 relates to Jenkins FilePath.untarFrom() where TAR extraction does not validate tar entry symlink targets, allowing an authenticated user with Item/Configure privileges to create workspace symlinks that point to arbitrary files on the Jenkins controller. This can enable reading sens...

CVE-2026-19429 Jenkins - FilePath.untarFrom() Symlink Target Validation Bypass and Blank-Name Check Bypass (Arbitrary File Read)

Jenkins FilePath.untarFrom does not validate symlink targets in extracted TAR archives, even in versions patched for CVE-2026-33001 and CVE-2026-70427. An authenticated attacker with job configuration privileges can include a malicious archive in a build step that creates workspace symlinks...

CVE-2026-19429

Jenkins FilePath.untarFrom does not validate symlink targets when extracting TAR archives, allowing an attacker with Item/Configure permission to create symlinks from a workspace to arbitrary files on the Jenkins controller. This issue remains exploitable in versions patched for CVE-2026-33001 an...

EUVD-2026-55615

Jenkins FilePath.untarFrom in all versions, including those with the CVE-2026-33001 patch applied, validates symlink destinations but not targets. The CVE-2026-33001 fix enforces that the symlink file is created within the workspace boundary, but the symlink target — the path returned by...

github.com/moby/go-archive: moby/go-archive: Arbitrary file write via link following in tar extraction

A flaw was found in moby/go-archive. The tar extraction routines in the component do not properly restrict filesystem operations to the intended destination directory. An attacker who controls the contents of an archive can exploit this by including symbolic links, allowing them to create or...

CVE-2026-66484

GNU cpio has a Path Traversal vulnerability in tar extraction (copy-in mode with --no-absolute-filenames). A tar archive with a hard-link entry whose linkname is an absolute path can cause a hard link to a file outside the extraction directory because the hard-link target is passed to link_to_nam...

tar: Node-tar: Denial of Service via malformed tar archive header

A flaw was found in node-tar, a tar archive manipulation library for Node.js. A remote attacker could exploit this vulnerability by providing a specially crafted tar archive with a negative entry size in its header. This malformed header causes the archive scanner to enter an infinite loop,...

tar: node-tar: Denial of Service via crafted gzip bomb

A flaw was found in node-tar, a tar archive manipulation library for Node.js. This vulnerability allows a remote attacker to craft a small gzip bomb, which, when processed, can lead to the exhaustion of disk space and CPU resources. This occurs because node-tar does not enforce strict limits on t...
