——1As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco Expressway Series software engineering team has conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-76497 are related to issues concerning insecure temporary files that are grouped under the Common Weakness Enumeration (CWE) Base CWE-377.4dCVE-2026-113713—3.2%
——1virtualenv is a tool for creating isolated virtual python environments. From 21.14.8 until 21.14.10, the app-data seeder can leave an environment linked to temporary package files that virtualenv deletes when creation finishes. The environment-variable and configuration-file forms of symlink_app_data can enable this state even though the command-line flag is disabled for temporary app-data. The resulting environment depends on a cache pathname that its owner no longer controls. This issue is fixed in version 21.14.10.5dCVE-2026-554805.7 MED10.1%
——3OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior to 2.4.20, copy_model() in scheduler/ipp.c creates a predictable TempDir/<connection-number>.ppd path in an lp-group-writable directory and opens it as root without O_EXCL or O_NOFOLLOW. Exploitation requires an lp-group process able to write that directory to predict the connection-derived name and plant a symlink before the root open, while a privileged add-printer or modify-printer operation using a model PPD triggers copy_model(). The reporter treats an existing lp foothold and the privileged operation as distinct prerequisites, while the maintainer assesses high privileges because installing the relevant filter or administering the printer requires root or print-administrator access. If the race succeeds, the root scheduler follows the symlink and truncates or overwrites a root-writable target with generated PPD data, compromising file integrity or availability. This issue is fixed in version 2.4.20.5dCVE-2026-827157.9 HIG2.2%
——1Insecure Temporary File vulnerability in Hitachi Disk Array Driver for AIX and Hitachi Disk Array Driver for Virtual I/O Server.
This issue affects Hitachi Disk Array Driver for AIX: from 01-00 before 01-23-/A; Hitachi Disk Array Driver for Virtual I/O Server: from 01-04 before 01-23-/A.8dCVE-2026-1102344.4 MED3.2%
——1Elio through 1.13.0 contains an insecure temporary file vulnerability that allows local users to overwrite another user's files by pre-creating symbolic links at predictable capture paths. Attackers who know the victim's Elio process ID can plant a symlink so previewing media, fonts or archives truncates and overwrites victim-owned files.12dCVE-2026-49484—22.1%
——7Code for IBM i is a Visual Studio Code extension for maintaining and compiling ILE languages on the IBMi platform. Prior to 3.0.1, src/ui/views/objectBrowser.ts stores Object Browser downloads and the edit-save flow content in the shared /tmp directory without reliable cleanup. On systems where /tmp is accessible to other local accounts, file contents remain readable after download or editing operations. This issue is fixed in version 3.0.1.10d
