Deeper analysis
YesWiki, a PHP-based wiki system, contains a path traversal vulnerability in its squelette parameter that permits unauthorized read access to arbitrary files on the underlying server. The flaw is tracked as CWE-22 and carries a CVSS 3.1 score of 8.6, reflecting network attackability without authentication or user interaction and a confidentiality impact that extends beyond the vulnerable component.
Unauthenticated remote attackers can supply crafted values to the squelette parameter and retrieve sensitive files such as configuration data or source code. Successful exploitation yields high-impact information disclosure while leaving integrity and availability unaffected.
The vulnerability is resolved in YesWiki 4.5.2. The project’s GitHub security advisory GHSA-w34w-fvp3-68xm and the associated commit f78c915369a60c74ab8f38561ae93a4aaca9b989 document the fix and recommend that administrators upgrade promptly.
