Privilege escalation in TeamViewer DEX via DeleteFileByPath instruction
Summary
Improper Link Resolution Before File Access (invoked by 1E‑Explorer‑TachyonCore‑DeleteFileByPath instruction) in TeamViewer DEX - 1E Client before version 26.1 on Windows allows a low‑privileged local attacker to delete protected system files via a crafted RPC control junction or symlink that is followed when the delete instruction executes.

Title
virtualenv Has TOCTOU Vulnerabilities in Directory Creation
Summary
virtualenv is a tool for creating isolated virtual python environments. Prior to version 20.36.1, TOCTOU (Time-of-Check-Time-of-Use) vulnerabilities in virtualenv allow local attackers to perform symlink-based attacks on directory creation operations. An attacker with local access can exploit a race condition between directory existence checks and creation to redirect virtualenv's app_data and lock file operations to attacker-controlled locations. This issue has been patched in version 20.36.1.

Title
filelock Time-of-Check-Time-of-Use (TOCTOU) Symlink Vulnerability in SoftFileLock
Summary
filelock is a platform-independent file lock for Python. Prior to version 3.20.3, a TOCTOU race condition vulnerability exists in the SoftFileLock implementation of the filelock package. An attacker with local filesystem access and permission to create symlinks can exploit a race condition between the permission validation and file creation to cause lock operations to fail or behave unexpectedly. The vulnerability occurs in the _acquire() method between raise_on_not_writable_file() (permission check) and os.open() (file creation). During this race window, an attacker can create a symlink at the lock file path, potentially causing the lock to operate on an unintended target file or leading to denial of service. This issue has been patched in version 3.20.3.

OpenClaw < 2026.3.2 - Path Confinement Bypass in Browser Output and File Write Operations
Summary
OpenClaw versions prior to 2026.3.2 contain a path-confinement bypass vulnerability in browser output handling that allows writes outside intended root directories. Attackers can exploit insufficient canonical path-boundary validation in file write operations to escape root-bound restrictions and write files to arbitrary locations.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

Title
Cisco ThousandEyes Enterprise Agent Arbitrary File Overwrite Vulnerability
Summary
A vulnerability in the CLI of Cisco ThousandEyes Enterprise Agent could allow an authenticated, local attacker with low privileges to overwrite arbitrary files on the local system of an affected device.
This vulnerability is due to improper access controls on files that are on the local file system of an affected device. An attacker could exploit this vulnerability by placing a symbolic link in a specific location on the local file system. A successful exploit could allow the attacker to bypass file system permissions and overwrite arbitrary files on the affected device.

Title
PAX Technology Q80 AIP File Parsing Link Following Remote Code Execution Vulnerability
Summary
PAX Technology Q80 AIP File Parsing Link Following Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of PAX Technology Q80. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the parsing of AIP files. By creating a symbolic link, an attacker can abuse the installer process to write arbitrary files. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-30583.

Mitigation MIT-48.1
Architecture and Design
Strategy: Separation of Privilege
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
CAPEC-132: Symlink Attack
An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.
CAPEC-17: Using Malicious Files
An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
CAPEC-35: Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
CAPEC-76: Manipulating Web Input to File System Calls
An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
