CVE-2025-46346 Details
Description
YesWiki is a wiki system written in PHP. Prior to version 4.5.4, a stored cross-site scripting (XSS) vulnerability was discovered in the application’s comments feature. This issue allows a malicious actor to inject JavaScript payloads that are stored and later executed in the browser of any user viewing the affected comment. The XSS occurs because the application fails to properly sanitize or encode user input submitted to the comments. Notably, the application sanitizes or does not allow execution of `<script>` tags, but does not account for payloads obfuscated using JavaScript block comments like `/* JavaScriptPayload */`. This issue has been patched in version 4.5.4.
A stored cross-site scripting vulnerability has been identified in YesWiki versions prior to 4.5.4. This issue arises in the comments feature, where the application fails to adequately sanitize user input. As a result, malicious actors can inject JavaScript payloads that are executed in the browsers of users viewing the affected comments. While the application blocks the execution of <script> tags, it does not recognize payloads hidden using JavaScript block comments. This vulnerability has been patched in version 4.5.4.
Users can update to YesWiki version 4.5.4 or later to address this vulnerability.
