Improper Link Resolution Before File Access ('Link Following')

The decompress package for Node.js extracts archives. Prior to 10.2.1 and 11.1.3, archive extraction can create files and links outside the target directory. When extracting an archive to a directory, a crafted archive can read or write files outside that directory because hardlink and symlink entries are created without checking where targets point, path containment used a string prefix comparison, and file modes failed to remove setuid, setgid, or sticky bits. This issue is fixed in @xhmikosr/decompress versions 10.2.1 and 11.1.3.Show less

DBD::File versions before 1.651 for Perl do not ensure the table file is not a symlink to an untrusted location. The complete_table_name method builds the absolute table file path without checking whether the file is a symbolic link. A link inside the data directory can point to a table file at any path outside of the configured f_dir and f_dir_search directories. Callers of file-based drivers can read or write files outside of the data directory.Show less

An Improper link resolution before file access ('link following') vulnerability in the File Shredder module as used in Bitdefender Total Security and Internet Security on Windows allows a less-privileged local user to elevate rights by leveraging a race conditions via Symbolic Links. This issue affects Total Security: before 27.0.58.315; Internet Security: before 27.0.58.315.Show less

A weakness has been identified in louisho5 picobot up to 0.2.0. Impacted is the function CreateSkill/GetSkill of the file internal/agent/tools/filesystem.go of the component Workspace Handler. Executing a manipulation can lead to link following. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.Show less

A vulnerability was detected in mosaxiv clawlet up to 0.2.10. This impacts the function read_file/write_file/edit_file of the file tools/fs_ops.go of the component File Tools. Performing a manipulation results in link following. The attack needs to be approached locally. The reported GitHub issue was closed with the label "not planned".Show less

FlashAttention through 2.8.3.post1, fixed in commit 0816ef1, contains a symlink attack vulnerability in the download_and_copy() function within hopper/setup.py that extracts NVIDIA toolchain archives without validating symlinks or filtering tar members. A local attacker can pre-plant a symlink in the predictable cache directory to redirect extracted binaries to an attacker-chosen location, enabling arbitrary file write with victim privileges during build time.Show less

OpenClaw versions before 2026.6.9 contain a symlink following vulnerability in the mirror sync feature that allows lower-trust callers to perform actions requiring stronger authorization. Attackers can exploit remote symlink parents to bypass policy checks and authorization boundaries when the feature is enabled and reachable.Show less

Glarysoft Glary Utilities Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Glarysoft Glary Utilities. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Disk Clean functionality. By creating a junction, an attacker can abuse the service to delete arbitrary files. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-27004.Show less

AnyDesk Support Information Link Following Denial-of-Service Vulnerability. This vulnerability allows local attackers to create a denial-of-service condition on affected installations of AnyDesk. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Send Support Information feature. By creating a junction, an attacker can abuse the service to create arbitrary files. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-26645.Show less

AnyDesk Screen Recording Link Following Denial-of-Service Vulnerability. This vulnerability allows local attackers to create a denial-of-service condition on affected installations of AnyDesk. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of screen recording files. By creating a junction, an attacker can abuse the service to create arbitrary files. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-26591.Show less

ImageMagick before 7.1.2-26 contains a policy bypass vulnerability in the APNG encoder and external delegates due to missing validation checks. Attackers can write files to disallowed paths by bypassing configured policy restrictions through the APNG encoding process.Show less

decompress before 4.2.2 allows arbitrary symlink creation during archive extraction. When processing symlink entries (type === 'symlink'), the x.linkname field from the archive is passed directly to fs.symlink() without validation (index.js line 121). The preventWritingThroughSymlink check on line 98 only applies to file entries, not symlink creation. An attacker can craft an archive with symlink entries pointing to sensitive files outside the extraction directory (e.g., /etc/passwd), enabling information disclosure when the application reads the extracted contents.Show less
