CVE-2022-1526
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability, which was classified as problematic, was found in Emlog Pro up to 1.2.2. This affects the POST parameter handling of articles. The manipulation with the input <script>alert(1);</script> leads to cross site scripting. It is possible to initiate the attack remotely but it requires a signup and login by the attacker. The exploit has been disclosed to the public and may be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA stored cross-site scripting (XSS) vulnerability exists in Emlog Pro up to version 1.2.2 in the article posting functionality. The application fails to properly sanitize or encode user-supplied input in POST parameters when creating or editing articles, allowing injection of malicious scripts such as <script>alert(1);</script> that persist on the server and execute in other users' browsers.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Emlog Pro versionAccess the admin dashboard and navigate to the About or System Information page, or inspect the version.php file in the root installation directory for a version identifierAffected if The installed version is 1.2.2 or lower
-
Verify article posting is accessibleLog into the Emlog admin panel and confirm the ability to access the article creation or edit functionality (typically at /admin/article.php or similar path)Affected if User has author, editor, or administrator privileges with access to create or edit content
-
Inspect stored article content for lack of encodingCreate a test article with a benign payload such as <img src=x onerror=alert(1)> in the title or content field, save it, then view the article as a different user or in the frontend to see if the payload renders as raw HTML instead of being entity-encodedAffected if The payload displays as executable HTML/JavaScript rather than being sanitized or displayed as plain text
If running Emlog Pro version 1.2.2 or lower and the article creation/editing feature is accessible to your user account, the stored XSS vulnerability is present and exploitable.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedImplement proper input validation and output encoding for all user-supplied content in article creation/edit forms. Use context-appropriate encoding (HTML encoding, attribute encoding) when rendering article content, and consider implementing a Content Security Policy (CSP) as a defense-in-depth measure.
Latest Emlog Pro release (version higher than 1.2.2)
- 1. Ensure you have a complete backup of your Emlog installation including database and all files.
- 2. Check Emlog's official GitHub repository (github.com/emlog/emlog) or official website for the latest version.
- 3. Upgrade Emlog to the latest available version (version 1.2.3 or later if available).
- 4. After upgrade, verify the XSS vulnerability is patched by attempting to insert a test script payload in the article POST parameter and confirming it is properly sanitized or escaped.
- 5. Clear any cached content if your Emlog installation uses caching.
