CVE-2025-3591 Overview
CVE-2025-3591 is a cross-site scripting (XSS) vulnerability [CWE-79] in ZHENFENG13 My-Blog-layui version 1.0. The flaw resides in unknown functionality of the /admin/v1/blog/edit endpoint. Attackers can manipulate multiple parameters to inject arbitrary script content that executes in the context of an authenticated administrator's browser. The vulnerability is exploitable remotely and requires low privileges combined with user interaction. Public exploit details have been disclosed. The vendor was contacted before disclosure but did not respond.
Critical Impact
Authenticated attackers can inject persistent script payloads through the blog edit endpoint, enabling session theft, administrative action hijacking, and further compromise of the blog platform.

Technical Details for CVE-2025-3591
Vulnerability Analysis
The vulnerability is a stored or reflected cross-site scripting flaw in the administrative blog edit workflow of My-Blog-layui 1.0. The /admin/v1/blog/edit handler accepts user-supplied parameters without applying sufficient output encoding or input sanitization. When an authenticated user views the affected content, injected HTML or JavaScript executes within the trusted origin of the blog application.
Multiple parameters on the edit endpoint are reported to be affected, expanding the injection surface. Because the endpoint is part of the admin panel, exploitation requires a low-privileged authenticated session and some form of user interaction such as opening a crafted post or preview page.
Root Cause
The root cause is missing or insufficient neutralization of user-controlled input before it is rendered in HTML output [CWE-79]. Blog post fields submitted to /admin/v1/blog/edit are stored and later reflected back into the application interface without contextual output encoding, allowing HTML and script content to be interpreted by the browser.
Attack Vector
The attack vector is network-based over HTTP(S). An attacker with access to an authenticated administrative session, or one who tricks a legitimate administrator into submitting or viewing crafted content, can deliver a payload through one of the affected edit parameters. Successful exploitation results in script execution in the victim's browser under the application's origin, enabling session cookie theft, forced administrative actions via CSRF-like abuse, and defacement of blog content.
See the GitHub proof-of-concept writeup and the VulDB entry #304646 for technical details on parameter selection and payload construction.
Detection Methods for CVE-2025-3591
Indicators of Compromise
- HTTP POST or PUT requests to /admin/v1/blog/edit containing <script>, onerror=, onload=, javascript:, or encoded variants in body parameters.
- Blog post records in the database containing unexpected HTML tags, inline event handlers, or references to external JavaScript resources.
- Outbound requests from administrator browsers to unfamiliar domains shortly after loading an admin blog page.
Detection Strategies
- Inspect web server and application access logs for administrative requests to /admin/v1/blog/edit with parameter values matching common XSS payload patterns.
- Deploy a Web Application Firewall (WAF) rule set that flags HTML and script primitives submitted to blog edit parameters.
- Perform periodic content audits of stored blog entries to identify persistent script content that should not exist in normal editorial workflow.
Monitoring Recommendations
- Enable Content Security Policy (CSP) violation reporting to capture inline script execution attempts on admin pages.
- Monitor administrator session activity for anomalous API calls immediately following blog edit or preview actions.
- Alert on new or modified administrator accounts, password changes, or privilege changes correlated with recent edit endpoint activity.
How to Mitigate CVE-2025-3591
Immediate Actions Required
- Restrict access to the /admin/v1/blog/edit endpoint using IP allowlists, VPN gating, or reverse-proxy authentication until a fix is available.
- Audit existing blog entries for injected HTML and script content and sanitize or remove affected records.
- Rotate administrator credentials and invalidate active sessions if suspicious activity is detected.
Patch Information
No vendor patch is available. The vendor was contacted about the disclosure but did not respond. Organizations running My-Blog-layui 1.0 should treat this as an unpatched issue and apply compensating controls. Track updates via the VulDB security context and the project's GitHub repository.
Workarounds
- Apply a WAF or reverse-proxy filter that strips or rejects HTML tags and event handler attributes in requests to /admin/v1/blog/edit.
- Enforce a strict Content Security Policy that disallows unsafe-inline scripts and restricts script sources to trusted origins.
- Perform server-side output encoding on all blog content rendered in HTML contexts, and limit blog editing to a small set of trusted accounts protected with multi-factor authentication.
