CVE-2026-14966 Symlink guard bypass in unarchive module allows planting symlinks during extraction

BBOT's unarchive module rejects archives containing symlink entries before extraction, but for zip and 7z archives it failed to detect symlinks whose listing carries a DOS-attribute prefix before the unix mode, as produced by legacy versions of p7zip. Such an archive, downloaded and extracted...

PT-2026-56543

Name of the Vulnerable Software and Affected Versions LiteLLM versions prior to 1.83.7-stable Description LiteLLM, a proxy server used to call LLM APIs, contains a flaw in its Skills archive extraction process. An authenticated user with access to the LLM API routes or a key permitted to use...

pip: pip: Incorrect file installation due to improper archive handling

A flaw was found in pip. This vulnerability occurs because pip incorrectly processes concatenated tar and ZIP files as ZIP files, regardless of their true format. This improper handling can lead to confusing installation behavior, potentially causing the installation of unintended or 'incorrect'...

Directory Traversal

Overview decompress is a package that can be used for extracting archives. Affected versions of this package are vulnerable to Directory Traversal and link following during archive extraction, where symlink and hardlink entries are created without checking their targets and the directory...

Decompress: Archive extraction can create files and links outside of the target directory

Impact When extracting an archive to a directory, a crafted archive can read or write files outside that directory. The flaw is in the code that writes the parsed entries, so it affects every format decompress handles: tar, tar.gz, tar.bz2, and zip by default, plus any others added through the...

python: Python tarfile module: Denial of Service via improper EOF handling in streaming mode

A flaw was found in the Python tarfile module. When processing a specially crafted tar archive opened in 'streaming mode' mode='r|', the module does not properly handle the end-of-file EOF condition. This can cause the tarfile module to enter an infinite loop, leading to a Denial of Service DoS f...

CVE-2026-12252 Untrusted JAR Code Execution in Multiple Stanford Interface Classes in nltk/nltk

In nltk/nltk versions 3.9.3 and earlier, five Stanford interface classes StanfordPOSTagger, StanfordNERTagger, StanfordParser, StanfordDependencyParser, and StanfordNeuralDependencyParser are vulnerable to untrusted JAR code execution. These classes accept user-controllable JAR paths and execute...

UBUNTU-CVE-2026-20243

A vulnerability in the ALZ file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition, or possibly other expanded impacts, resulting from memory corruption on an affected device. This vulnerability is due to improper boundary checks for content in ALZ...

vim: command injection when decompressing .tgz archives

A flaw was found in Vim. When decompressing .tgz archives, the Vimuntar function builds shell commands using shellescape without the special flag. This allows a specially crafted archive filename to trigger Vim cmdline-special expansion and execute arbitrary commands in the context of the current...

vim: zip.vim: Vim zip.vim plugin: Arbitrary file overwrite via path traversal bypass

A flaw was found in Vim's zip.vim plugin. A local user could be tricked into opening a specially crafted zip archive, which would allow a path traversal bypass. This vulnerability enables an attacker to overwrite arbitrary files on the system, potentially leading to data integrity issues or furth...
