CVE-2026-12482

Full vulnerability record from the local CVENow database.

Description

A vulnerability in keras-team/keras version 3.12.0 allows an attacker to craft a malicious tar archive that bypasses the `filter_safe_tarinfos` validation in `keras/src/utils/file_utils.py`. Specifically, symlink entries are not subjected to the same `is_path_in_dir` validation as regular file entries, allowing symlinks to be created outside the intended extraction directory. This can lead to symlink-based file read, file overwrite, or directory escape attacks. The issue is particularly impactful on Python 3.10 and 3.11, where `filter_safe_tarinfos` is the sole defense against tar path traversal. This vulnerability is distinct from CVE-2025-12060 and other previously reported issues.

      "value": "Una vulnerabilidad en keras-team/keras versión 3.12.0 permite a un atacante crear un archivo tar malicioso que omite la validación “filter_safe_tarinfos” en “keras/src/utils/file_utils.py”. Específicamente, las entradas de enlaces simbólicos no están sujetas a la misma validación “is_path_in_dir” que las entradas de archivos regulares, lo que permite que se creen enlaces simbólicos fuera del directorio de extracción previsto. Esto puede conducir a ataques de lectura o sobrescritura de archivos, o de escape de directorio, basados en enlaces simbólicos. El problema es particularmente impactante en Python 3.10 y 3.11, donde “filter_safe_tarinfos” es la única defensa contra el salto de ruta de tar. Esta vulnerabilidad es distinta de CVE-2025-12060 y de otros problemas reportados anteriormente."
