CVE-2025-13971: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in thewellnessway TWW Protein Calculator
The TWW Protein Calculator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Header' setting in all versions up to, and including, 1.0.24 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
AI Analysis
Technical Summary
CVE-2025-13971 is a stored cross-site scripting vulnerability in thewellnessway's TWW Protein Calculator WordPress plugin affecting all versions up to 1.0.24. The flaw exists due to improper neutralization of input in the 'Header' setting, allowing authenticated administrators on multi-site WordPress installations or those with unfiltered_html disabled to inject arbitrary scripts. These scripts execute in the context of users accessing the injected pages, potentially leading to limited confidentiality and integrity impacts. The vulnerability requires high privileges and no user interaction, with a CVSS 3.1 base score of 4.4.
Potential Impact
An attacker with administrator-level access on a multi-site WordPress installation or a site with unfiltered_html disabled can inject persistent malicious scripts via the 'Header' setting. This could lead to limited confidentiality and integrity impacts by executing arbitrary scripts in users' browsers when they access the affected pages. There is no indication of availability impact. The vulnerability does not affect single-site installations or sites where unfiltered_html is enabled. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — no official fix or patch information is provided. Administrators should monitor the vendor's advisory channels for updates. Until a patch is available, limit administrator access to trusted users and consider enabling unfiltered_html if feasible. Multi-site installations should be especially cautious. No vendor advisory states that no action is required or that the issue is already mitigated.
