Title
Rhc: rhc: local privilege escalation via symlink following in rhc-canonical-facts.service
Summary
A flaw was found in the rhc-canonical-facts.service systemd unit shipped with rhc. The service runs as root and operates on a file inside a directory owned by an unprivileged system user without verifying that the file is not a symbolic link. A local attacker who has already compromised the privileged yggdrasil system service account can exploit this to gain ownership of arbitrary files, leading to privilege escalation to root.

Title
Nautilus: nautilus: arbitrary file deletion via trash symlink
Summary
A flaw was found in Nautilus. When a removable drive or disk image is unmounted or ejected, Nautilus prompts the user to empty the trash without verifying whether the trash directory paths are symbolic links. An attacker can exploit this flaw by tricking a user into mounting a crafted storage volume and confirming the prompt to empty the trash, leading to the arbitrary deletion of files accessible to that user.

CVE-2026-111045 (GCVE-0-2026-111045)

Title
CLI Bridge: High-severity sandbox escape via dangling symlink
Summary
CLI Bridge provides filesystem access within a workspace root. Prior to 0.0.2, a dangling symlink pointing outside the workspace root bypasses resolveSafePath when fs.realpathSync throws ENOENT for a nonexistent target. The fallback resolves only the parent directory and returns the symlink path as safe, so write_file follows the link and can write arbitrary files outside the workspace root. This issue is fixed in version 0.0.2.

CVE-2026-110860 (GCVE-0-2026-110860)

Vulnerability from cvelistv5 – Published: 2026-10-14 22:52 – Updated: 2026-10-14 22:52

Title
GitPython 3.1.62 before 3.2.0 Symlink Path Traversal via Submodule.move()
Summary
GitPython from 3.1.62 before 3.2.0 contains a symlink-following flaw in Submodule.move(), which checks the destination only lexically and does not reject symbolic links in intermediate path components. An untrusted repository can commit a symlink such as vendor pointing outside the worktree, so an application moving an initialized submodule beneath it relocates the checkout externally and corrupts the index and .gitmodules.

Title
Gitingest through 0.3.1 Arbitrary File Read via Symlink in Blob Ingestion
Summary
Gitingest through 0.3.1 contains a symlink following vulnerability in ingest_query single-file blob ingestion that allows unauthenticated attackers to read server files by submitting symlink blob URLs. Attackers can commit a symlink to a public repository and submit its blob URL, causing the server to return any file the service user can read, up to 10 MB.

Title
Serena before 2.0.0 Symlink Following in File Tools Allows Access Outside Project Root
Summary
Serena before 2.0.0 contains an improper link resolution vulnerability that allows attackers to access files outside the project root by committing symlinks inside a repository. Project.is_path_in_project() normalizes paths lexically without resolving symlinks, so file tools like read_file and create_text_file can read or overwrite files such as SSH keys or cloud credentials.

Title
Hugo from v0.162.0 before v0.167.0 Symlink File Disclosure via Nested Mount Ancestor
Summary
Hugo from v0.162.0 before v0.167.0 contains an improper link resolution vulnerability that lets malicious themes or modules expose files outside their root via nested-mount ancestor directories. Attackers controlling a theme can place a symlink or NTFS junction at a virtual ancestor directory, causing resources.Match to list and publish local files during builds.

Title
Vercel deepsec before 1.1.17 Arbitrary File Write via Symlink in Sandbox Tarball Extraction
Summary
Vercel deepsec from 0.1.0 before 1.1.17 contains a link following vulnerability in extractTarballLocally that allows sandboxed code to write files outside the sandbox by planting links in result tarballs. Attackers controlling sandbox code, such as a prompt-injected coding agent, can plant symbolic or hard links in the host data directory to write arbitrary files on the orchestrator host.

Title
ImageMagick before 7.1.2-32 TOCTOU Symlink Race Path Policy Bypass via magick script
Summary
ImageMagick before 7.1.2-32 contains a time-of-check time-of-use symlink race vulnerability that allows attackers to bypass the path security policy when executing a magick script. Attackers can swap a checked path with a symlink during script execution to read files that the security policy is meant to block.

CVE-2026-108839 (GCVE-0-2026-108839)

Vulnerability from cvelistv5 – Published: 2026-10-11 13:26 – Updated: 2026-10-18 11:53
VLAI
Title
thClaws through 0.141.0 Symlink Following File Write via POST /v1/inputs
Summary
thClaws through 0.141.0 contains a link-following vulnerability in the post_inputs handler of the v1 API POST /v1/inputs endpoint that allows writes outside the workspace by following symlinks. Attackers who plant a symlink under the allowed inputs/ prefix can cause later authenticated uploads to write or truncate files outside the workspace with daemon privileges.

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.
