CVE-2026-12567 (GCVE-0-2026-12567)

Vulnerability from cvelistv5 – Published: 2026-06-17 21:51 – Updated: 2026-06-18 12:50
VLAI
Title
Symlink-following arbitrary write via github_workflows module
Summary
The github_workflows module constructs local directory paths from user-controlled repository names without validating for symlinks. A local attacker sharing the scan directory can plant a symlink at the predictable output path, causing workflow data to be written to an attacker-chosen location.

CVE-2026-11940 (GCVE-0-2026-11940)

Vulnerability from cvelistv5 – Published: 2026-06-23 16:04 – Updated: 2026-06-30 15:13

Title
tarfile extraction filter bypass allows escaping the destination directory
Summary
tarfile.extractall() with the 'data' or 'tar' filter could be bypassed by a crafted archive where a hardlink references a symlink stored at a deeper name than the hardlink itself.  The extraction fallback validated the symlink at it's archived location but recreated it at the hardlink's shallower path, letting a relative target the filter judged contained escape the destination directory.  This allowed a malicious tar archive to create a symlink pointing outside the destination, enabling out-of-destination file reads or writes. This was an incomplete fix of CVE-2025-4330.

CVE-2026-11837 (GCVE-0-2026-11837)

Vulnerability from cvelistv5 – Published: 2026-06-10 05:03 – Updated: 2026-07-15 01:23
VLAI
Title
Ansible-collection-ansible-posix: ansible.posix authorized_key: local privilege escalation via symlink-following chown
Summary
A local privilege escalation vulnerability was found in the ansible.posix authorized_key module. The module's keyfile() function uses os.chown() instead of os.lchown() and opens files without O_NOFOLLOW when managing SSH authorized keys. An unprivileged local user can pre-stage symbolic links in their ~/.ssh directory to redirect file ownership changes to arbitrary system paths when an operator runs the authorized_key task as root, leading to local privilege escalation.

CVE-2026-11322 (GCVE-0-2026-11322)

Title
Hermes WebUI before 0.51.221 Path Traversal via Symlink Workspace Bypass
Summary
Hermes WebUI prior to v0.51.221 contains a path traversal vulnerability that allows attackers to escape the workspace boundary by supplying symlinks that resolve to files or directories outside the designated workspace root. Attackers can exploit the workspace file and listing APIs, which resolve symlink targets without enforcing that the final path remains within the workspace, to read external host files accessible to the server process and disclose sensitive data such as SSH keys, cloud credentials, or application tokens.

CVE-2026-9804 (GCVE-0-2026-9804)

Vulnerability from cvelistv5 – Published: 2026-05-28 08:15 – Updated: 2026-07-15 00:38

Title
Kubevirt: kubevirt: vmexport directory symlink escape enables exporter pod file read
Summary
A flaw was found in KubeVirt's virt-exportserver component. An attacker with specific namespace-level access can exploit a path traversal vulnerability in the VMExport directory endpoint. By placing a symbolic link (symlink) within an exported filesystem Persistent Volume Claim (PVC) that points outside its designated mount root, the attacker can read arbitrary files from the exporter pod's filesystem. This leads to information disclosure, potentially exposing sensitive data.

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.
