CVE-2026-50163 oras-go: Hardlink entry with relative Linkname escapes extract dir via process CWD resolution in `oras-go` tar extraction

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, ensureLinkPath in content/file/utils.go:262-275 validates a hardlink target relative to the extract base but returns the unresolved target, causing os.Link"victim.secret", "/payload.tar.gz/evilcwdlink" to resolve header.Linkname...

CVE-2026-50163

The CVE concerns the oras-go library (OCI artifacts) prior to version 2.6.2, where ensureLinkPath in content/file/utils.go can return an unresolved hardlink target. During tar extraction, a hardlink entry with a relative Linkname could be resolved against the process CWD, allowing a path like pay...

Amazon Linux 2023 : python3.14, python3.14-devel, python3.14-freethreading (ALAS2023-2026-1929)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1929 advisory. tarfile.extractall with the 'data' or 'tar'filter could be bypassed by a crafted archive where a hardlinkreferences a symlink stored at a deeper name than the hardlink itself.The extraction...

CVE-2026-12482

The CVE-2026-12482 entry concerns keras-team/keras 3.12.0. A crafted tar archive can bypass filter_safe_tarinfos in keras/src/utils/file_utils.py, because symlink entries are not consistently validated by is_path_in_dir as regular files, enabling symlinks to escape the extraction directory. Poten...

CVE-2026-12482 Path Traversal via Symlink Name Validation Bypass in keras-team/keras

A vulnerability in keras-team/keras version 3.12.0 allows an attacker to craft a malicious tar archive that bypasses the filtersafetarinfos validation in keras/src/utils/fileutils.py. Specifically, symlink entries are not subjected to the same ispathindir validation as regular file entries,...

PYSEC-2026-2378 Microsoft APM: Windows absolute-path tar member overwrite during legacy-bundle probing in `apm install`

Summary Microsoft APM contains a Windows-specific archive extraction boundary failure in the legacy-bundle probe used by apm install on supported Python 3.10 and 3.11 runtimes. When apm install is given a local .tar.gz that is not recognized as a plugin-format bundle, APM probes whether it is a...

PYSEC-2026-2890 Poetry has Path Traversal in tar extraction on Python 3.10.0 - 3.10.12 and 3.11.0 - 3.11.4

Summary The extractall function in src/poetry/utils/helpers.py:410-426 extracts sdist tarballs without path traversal protection on Python versions where tarfile.datafilter is unavailable. Considering only Python versions which are still supported by Poetry, these are 3.10.0 - 3.10.12 and 3.11.0 ...

PYSEC-2026-2912 PraisonAI Vulnerable to Decompression Bomb DoS via Recipe Bundle Extraction Without Size Limits

Summary The safeextractall function in PraisonAI's recipe registry validates archive members against path traversal attacks but performs no checks on individual member sizes, cumulative extracted size, or member count before calling tar.extractall. An attacker can publish a malicious recipe bundl...

PYSEC-2026-2900 PraisonAI recipe registry pull path traversal writes files outside the chosen output directory

Summary PraisonAI's recipe registry pull flow extracts attacker-controlled .praison tar archives with tar.extractall and does not validate archive member paths before extraction. A malicious publisher can upload a recipe bundle that contains ../ traversal entries and any user who later pulls that...

PYSEC-2026-2398 BentoML Vulnerable to Arbitrary File Write via Symlink Path Traversal in Tar Extraction

Arbitrary File Write via Symlink Path Traversal in Tar Extraction Summary The safeextracttarfile function validates that each tar member's path is within the destination directory, but for symlink members it only validates the symlink's own path, not the symlink's target. An attacker can create a...

CVE-2026-58198

ChatterBot is a machine learning, conversational dialog engine for creating chat bots. Prior to 1.2.14, UbuntuCorpusTrainer.extract uses a predictable home-rooted output directory /ubuntudata/ubuntudialogs with a check-then-create pattern followed by tar.extractallpath=self.datapath, allowing a...
