CVE-2026-25701 (GCVE-0-2026-25701)
Vulnerability from cvelistv5 – Published: 2026-02-25 10:59 – Updated: 2026-02-25 20:50
VLAI
Summary
An Insecure Temporary File vulnerability in openSUSE sdbootutil allows local users to pre-create a directory to achieve various effects like:
* gain access to possible private information found in /var/lib/pcrlock.d
* manipulate the data backed up in /tmp/pcrlock.d.bak, therefore violating the integrity of the data should it be restored.
* overwrite protected system files with data from /var/lib/pcrlock.d by placing symlinks to existing files in the directory tree in /tmp/pcrlock.d.bak.
This issue affects sdbootutil: from ? before 5880246d3a02642dc68f5c8cb474bf63cdb56bca.

CVE-2026-35342 (GCVE-0-2026-35342)

Title
uutils coreutils mktemp Insecure Temporary File Placement via Empty TMPDIR
Summary
The mktemp utility in uutils coreutils fails to properly handle an empty TMPDIR environment variable. Unlike GNU mktemp, which falls back to /tmp when TMPDIR is an empty string, the uutils implementation treats the empty string as a valid path. This causes temporary files to be created in the current working directory (CWD) instead of the intended secure temporary directory. If the CWD is more permissive or accessible to other users than /tmp, it may lead to unintended information disclosure or unauthorized access to temporary data.

CVE-2026-40973 (GCVE-0-2026-40973)
Vulnerability from cvelistv5 – Published: 2026-04-27 23:29 – Updated: 2026-04-29 03:55
VLAI
Summary
A local attacker on the same host as the application may be able to take control of the directory used by `ApplicationTemp`. When `server.servlet.session.persistent` is set to `true` and the attack persists across application restarts, this may allow the attacker to read session information and hijack authenticated users or deploy a gadget chain and execute code as the application's user.
Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); predictable temp directory / `ApplicationTemp` ownership verification. Versions that are no longer supported are also affected per vendor advisory.

CAPEC-149: Explore for Predictable Temporary File Names
An attacker explores a target to identify the names and locations of predictable temporary files for the purpose of launching further attacks against the target. This involves analyzing naming conventions and storage locations of the temporary files created by a target application. If an attacker can predict the names of temporary files they can use this information to mount other attacks, such as information gathering and symlink attacks.
CAPEC-155: Screen Temporary Files for Sensitive Information
An adversary exploits the temporary, insecure storage of information by monitoring the content of files used to store temp data during an application's routine execution flow. Many applications use temporary files to accelerate processing or to provide records of state across multiple executions of the application. Sometimes, however, these temporary files may end up storing sensitive information. By screening an application's temporary files, an adversary might be able to discover such sensitive information. For example, web browsers often cache content to accelerate subsequent lookups. If the content contains sensitive information then the adversary could recover this from the web cache.
