CVE-2026-30452: n/a
Textpattern CMS version 4. 9. 0 has a Broken Access Control vulnerability in its article management system. Authenticated users with low privileges can exploit this flaw by manipulating the article ID parameter during the duplicate-and-save process to modify articles owned by users with higher privileges. This bypasses authorization checks and allows unauthorized content modification. The vulnerability has a CVSS score of 6. 5, indicating a medium severity level. No official patch or remediation guidance is currently available, and no known exploits have been reported in the wild.
AI Analysis
Technical Summary
CVE-2026-30452 describes a Broken Access Control vulnerability in Textpattern CMS 4.9.0. The issue exists in the article management system, specifically in the duplicate-and-save workflow implemented in textpattern/include/txp_article.php. By manipulating the article ID parameter, an authenticated user with low privileges can bypass authorization controls and overwrite articles owned by users with higher privileges. This vulnerability is classified under CWE-284 (Improper Access Control) and has a CVSS 3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N), indicating network attack vector, low attack complexity, requiring low privileges, no user interaction, unchanged scope, no confidentiality impact, high integrity impact, and no availability impact.
Potential Impact
The vulnerability allows an authenticated low-privilege user to modify content owned by higher-privilege users, resulting in unauthorized content alteration. This can undermine content integrity within the CMS but does not affect confidentiality or availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the article management system to trusted users only and monitor for unusual activity related to article duplication and saving. Avoid granting unnecessary privileges to users. No official patch or workaround is currently documented.
