CVE-2026-48099: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in mar10 wsgidav
WsgiDAV versions 4.3.3 and earlier contain a path traversal vulnerability that allows a WebDAV request path with an encoded parent-directory segment to escape the configured filesystem share root. This issue is resolved in version 4.3.4.
AI Analysis
Technical Summary
WsgiDAV, a WebDAV server based on WSGI, has a CWE-22 path traversal vulnerability in versions 4.3.3 and prior. The vulnerability arises when a WebDAV request path includes an encoded parent-directory segment, enabling an attacker to access files outside the intended filesystem share root under specific path layouts. This could lead to unauthorized access to sensitive files. The issue is fixed in version 4.3.4.
Potential Impact
Successful exploitation allows an attacker with low privileges to bypass filesystem restrictions and access or potentially modify files outside the intended directory. The CVSS score of 7.1 reflects high confidentiality and integrity impact with low availability impact. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Upgrade WsgiDAV to version 4.3.4 or later to remediate this vulnerability. Patch status is confirmed by the vendor's versioning information. No other mitigations are specified.
