CVE-2018-20250
In WinRAR versions prior to and including 5.61, There is path traversal vulnerability when crafting the filename field of the ACE format (in UNACEV2.dll). When the filename field is manipulated with specific patterns, the destination (extraction) folder is ignored, thus treating the filename as an absolute path.

Same Weakness Type(CWE-36)
BPMFlowWebkit developed by WELLTEND TECHNOLOGY has a Arbitrary File Read vulnerability, allowing unauthenticated remote attackers to exploit Absolute Path Traversal to download arbitrary system files.
Barracuda Service Center, as implemented in the RMM solution, in versions prior to 2025.1.1, does not verify the URL defined in an attacker-controlled WSDL that is later loaded by the application. This can lead to arbitrary file write and remote code execution via webshell upload.
NAKIVO Backup & Replication before 11.0.0.88174 allows absolute path traversal for reading files via getImageByPath to /c/router (this may lead to remote code execution across the enterprise because PhysicalDiscovery has cleartext credentials).
Absolute path traversal in Ivanti EPM before the 2024 January-2025 Security Update and 2022 SU6 January-2025 Security Update allows a remote unauthenticated attacker to leak sensitive information.
Absolute path traversal in Ivanti EPM before the 2024 January-2025 Security Update and 2022 SU6 January-2025 Security Update allows a remote unauthenticated attacker to leak sensitive information.
Similar SeverityHIGH
Improper link resolution before file access ('link following') in Microsoft Defender allows an authorized attacker to elevate privileges locally.
Improper neutralization of input during web page generation ('cross-site scripting') in Microsoft Exchange Server allows an unauthorized attacker to perform spoofing over a network.
An Improper Input Validation in Ivanti EPMM before versions 12.6.1.1, 12.7.0.1, and 12.8.0.1 allows a remotely authenticated user with administrative access to achieve remote code execution.
OpenClaw before 2026.4.22 contains a server-side request forgery vulnerability in the Zalo plugin's sendPhoto function that fails to validate outbound photo URLs through the SSRF guard. Attackers can bypass SSRF protection by providing malicious photo URLs to the Zalo Bot API, enabling unauthorized access to internal resources.
OpenClaw before 2026.4.22 contains an exec allowlist analysis vulnerability allowing shell expansion hiding in unquoted heredoc bodies. Attackers can bypass allowlist validation by embedding shell expansion tokens in heredoc bodies to execute unapproved commands at runtime.
