GHSA-W8WR-V893-VJVP node-tar: Process crash via PAX numeric path type confusion

Summary A crafted 2.5KB tar archive crashes any Node.js process that extracts it. The PAX header parser coerces all-digit path values to JavaScript numbers, which causes an uncaught TypeError when downstream code calls .split'/' on the numeric value. Error handlers and strict: false cannot...

GHSA-GVWX-54WH-QM9J node-tar: Uncaught Exception DoS via NUL byte in PAX path/linkpath records

Summary node-tar strips trailing NUL bytes from long-name L and long-linkpath K GNU extended headers but does not apply the same sanitization to equivalent fields delivered via PAX x typeflag extended headers. A PAX record of the form path=visible.txt\x00hidden.txt is parsed verbatim into...

Amazon Linux 2023 : python3.12, python3.12-devel, python3.12-idle (ALAS2023-2026-1954)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1954 advisory. When using the configparser module to write configuration filescontaining multi-line text values with carriage return characters \r theresulting file could be injected with unexpected keys and...

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...

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...

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

CVE-2026-12482 affects keras-team/keras v3.12.0. A path-traversal issue arises in tar extraction: symlink entries bypass the is_path_in_dir validation used for regular files in keras/src/utils/file_utils.py due to imperfect filter_safe_tarinfos. This allows crafting a malicious tar to place or re...

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 ...
