Attack Vector: Local
Attack Complexity: Low
Privileges Required: None
User Interaction: Required
Scope: Unchanged
Confidentiality: None
Integrity: Low
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 30 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Until an official fix is available, users should consider disabling the automatic folder creation feature or avoid extracting archives from untrusted sources to mitigate risk.

Description

CVE-2026-41530 is a path traversal vulnerability in Chitora soft's Lhaz and Lhaz+ archive extraction software. The issue occurs when the automatic folder creation feature is enabled and a user extracts an archive containing specially crafted file names. This can cause files to be extracted outside the intended directory. The vulnerability affects versions 2.6.3 and earlier. The CVSS score is 3.3, indicating low severity, with limited impact on integrity and no impact on confidentiality or availability. No official patch or remediation guidance is currently available, and no known exploits are reported in the wild.

Impact

The impact is limited to potential integrity issues where files may be extracted outside the intended directory, possibly overwriting or placing files in unexpected locations. There is no impact on confidentiality or availability. The vulnerability requires local access and user interaction to exploit, reducing the risk level. No known exploits have been reported in the wild.

Summary

The vulnerability in Lhaz and Lhaz+ arises from improper limitation of pathnames during archive extraction when automatic folder creation is enabled. Crafted filenames in an archive can cause files to be extracted to unintended directories, potentially leading to limited integrity issues. This affects Lhaz versions 2.6.3 and earlier. The CVSS 3.0 base score is 3.3, reflecting low severity with local attack vector, low complexity, no privileges required, and user interaction needed.
