CVE-2026-55828

qbee transport is a remote access transport protocol implementation. Prior to 1.26.25, the extractTar routine uses strictly lexical path validation that does not account for on-disk symlinks created earlier in the extraction process. A crafted tar archive can use a symlink chain to write or...

UBUNTU-CVE-2026-82455

RubyGems fails to re-validate path containment after filesystem symlink resolution during gem extraction. When a pre-existing symlink inside the destination directory points outside the extraction root, extracted files that appear to be written under the destination directory can instead be writt...

Smarty: Symlink path traversal out of trusted directories

When Smarty's Security policy is enabled, securedir and the configured template/trusted directories restrict which local files a template may read via include and fetch. The trust check in Security::checkDir resolved the requested path with Smarty::realpath, which normalizes the path as a string...

CVE-2026-62992

Smarty (PHP template engine) prior to 5.8.2 and 4.5.7 (4.x line) is affected by a symlink path-traversal in Security::_checkDir() that does not fully resolve symbolic links before validating the directory containment. An attacker who can place or reference a symlink inside a trusted Smarty direct...

On Unix systems, opening a file in an os.Root improperly follows symlinks to locations outside of the Root when the final path component of the a path is a symbolic link and the path ends in /. For example, 'root.Open"symlink/"' will open "symlink" even when "symlink" is a symbolic link pointing...

Important: python3.14

Issue Overview: tarfile.extractall with the 'data' or 'tar' filter could be bypassed by a crafted archive where a hardlink references a symlink stored at a deeper name than the hardlink itself. The extraction fallback validated the symlink at it's archived location but recreated it at the...
