Details

squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link and then contents under the same filename in a filesystem can cause unsquashfs to first create the symbolic link pointing outside the expected directory, and then the subsequent write operation will cause the unsquashfs process to write through the symbolic link elsewhere in the filesystem.

Details

FastNetMon Community Edition through 1.2.9 is vulnerable to a local symlink attack via predictable file paths in /tmp. The statistics file path defaults to '/tmp/fastnetmon.dat' (src/fastnetmon.cpp line 159). The print_screen_contents_into_file() function (src/fastnetmon_logic.cpp line 2186) opens this path with std::ios::trunc without checking for symlinks or using O_NOFOLLOW. Additionally, the chmod() call on line 2190 always operates on cli_stats_file_path regardless of which file_path parameter was passed (a bug that applies wrong permissions), and the umask is set to 0 during daemonization (src/fastnetmon.cpp line 1821), making all created files world-writable. A local attacker can exploit this to overwrite arbitrary files as the FastNetMon process user (typically root).

GHSA-F7WW-2725-QVW2

Vulnerability from github – Published: 2026-03-02 23:35 – Updated: 2026-03-18 21:53
VLAI
Summary
OpenClaw: Node system.run approval bypass via parent-symlink cwd rebind
Details

Summary

For host=node executions, approval context could be bypassed after approval-time by rebinding a writable parent symlink in cwd while preserving the visible cwd string.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: <= 2026.2.25
  • Fixed: >= 2026.2.26 (planned next npm release)

Impact

A command approved for one filesystem location could execute from a different location if a mutable parent symlink changed between approval and execution.

Fix

  • Added immutable approval-time plan preparation (system.run.prepare) and systemRunPlanV2 canonical fields (argv, cwd, agentId, sessionKey).
  • Enforced canonical plan values through approval request storage and forwarding-time sanitization.
  • Rejected mutable parent-symlink path components during approval-plan building to block symlink rebind bypass.
  • Follow-up refactors centralized command catalogs and approval context/error handling to reduce future drift.

  • 4b4718c8dfce2e2c48404aa5088af7c013bed60b

Release Process Note

patched_versions is pre-set to the planned next release (2026.2.26). Once npm openclaw@2026.2.26 is published, publish this advisory directly without further version-field edits.

OpenClaw thanks @tdjackey for reporting.

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.
