CVE-2026-73613 (GCVE-0-2026-73613)

Title
filebrowser before 2.63.19 Out-of-Scope File Deletion via Symlink
Summary
filebrowser versions before 2.63.19 contain an out-of-scope file deletion vulnerability in the TUS upload cache eviction mechanism that allows authenticated users with only Create permission to delete arbitrary files outside their scope. Attackers can swap an ancestor directory with a symlink during the cache TTL window to redirect the raw os.Remove call to an out-of-scope target, bypassing ScopedFs scope guards and Perm.Delete checks.

CVE-2026-72694 (GCVE-0-2026-72694)

Vulnerability from cvelistv5 – Published: 2026-08-11 08:37 – Updated: 2026-08-12 15:35

Title
Mrtg: mrtg daemon symlink-following chown allows local privilege escalation via pid file path manipulation
Summary
A flaw was found in MRTG. When the MRTG daemon is started as a root user and subsequently drops privileges, a local, low-privileged attacker can exploit a symbolic link (symlink) following vulnerability. By influencing or pre-placing a symlink in the process ID (PID) file path, the attacker can trick the root process into changing the ownership of an arbitrary existing file to the daemon user. This can lead to local privilege escalation, allowing unauthorized access to or modification of sensitive files.

Title
CyberPanel 2.4.3 Arbitrary File Read via File Manager ZIP Upload
Summary
CyberPanel 2.4.3, fixed in commit eca0c3c, contains an arbitrary file read vulnerability in the file manager component that allows authenticated attackers to read sensitive system files by uploading a crafted ZIP archive containing symbolic links. Attackers can exploit the application's failure to validate symlinks before extraction, causing symbolic links targeting arbitrary filesystem paths outside the user's home directory to persist on disk and be accessed through the web interface.

CVE-2026-71556 (GCVE-0-2026-71556)

Vulnerability from cvelistv5 – Published: 2026-08-07 16:37 – Updated: 2026-08-07 16:58

Title
go-git: Worktree operations may follow symlinks
Summary
go-git is an extensible git implementation library written in pure Go. Prior to 5.19.2 and 6.0.0-alpha.5, worktree operations (including checkout, status, and add) resolve symbolic links inside the working tree without confining resolution to the worktree boundary, so a maliciously crafted repository containing a symlink can cause go-git to read from or write to files outside the intended working directory when the repository is cloned and its worktree operations are used. Versions 5.19.2 and 6.0.0-alpha.5.

CVE-2026-71476 (GCVE-0-2026-71476)

Vulnerability from cvelistv5 – Published: 2026-08-06 20:07 – Updated: 2026-08-08 02:33

Title
Nx: Zip-Slip in the self-hosted remote cache
Summary
Nx is a monorepo solution for TypeScript and polyglot codebases. From version 20.8.0 until 22.7.7 and 23.0.2, the Nx self-hosted HTTP remote cache extracts downloaded cache artifacts without constraining where files are written. A malicious or on-path (MITM) remote cache server can return a crafted tar archive whose entries escape the cache directory and write to arbitrary locations on the machine running Nx, which can be escalated to remote code execution. Nx's default local cache and Nx Cloud are not affected; only workspaces configured to use a self-hosted remote cache are affected. This issue is fixed in versions 22.7.7 and 23.0.2.
Severity
8.7 (High)

CVE-2026-70622 (GCVE-0-2026-70622)

Title
tar-rs 0.4.11 - 0.4.46 Symlink Escape via append_dir_all()
Summary
tar-rs versions 0.4.11 through 0.4.46 contain a symlink escape vulnerability in the Builder::append_dir_all() function that allows attackers to read files outside the intended source root directory by planting symlinks in an attacker-controlled directory. When a privileged process archives an untrusted directory, the function follows symlinks without verifying that resolved targets remain within the source root, causing out-of-bounds files to be included in the archive as regular files and disclosed to the attacker.

CVE-2026-70460 (GCVE-0-2026-70460)

Vulnerability from cvelistv5 – Published: 2026-08-13 14:43 – Updated: 2026-08-13 14:43

Title
rsync 2.3.3 < 3.5.0 Path Traversal via --partial-dir/--backup-dir Symlink
Summary
rsync 2.3.3 before 3.5.0 contains a path traversal vulnerability that allows a malicious sender to escape the module root by exploiting symlinks within the module file tree when using --partial-dir or --backup-dir options. Attackers with write access to place a symlink under the module root, or who can exploit a pre-existing trusted symlink, can direct file writes to locations outside the intended module root, achieving arbitrary file write relative to the module root parent.
Severity

Title
Linuxfabrik monitoring-plugins: Symlink following in logfile legacy database migration
Summary
Linuxfabrik monitoring-plugins provides Python monitoring plugins for Icinga, Nagios, and related monitoring systems. In version 6.0.0, the logfile check legacy database migration moved a predictable path from /tmp with os.rename() and allowed a local user controlling the plugin account to place a symlink that would be followed by sqlite3.connect() during a root-run check.
Severity

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.
