CVE-2025-4776: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in averta Phlox
The Phlox theme for WordPress is vulnerable to Stored Cross-Site Scripting via the `data-caption` HTML attribute in all versions up to, and including, 2.17.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2025-4776 is a stored cross-site scripting vulnerability in the averta Phlox WordPress theme affecting all versions up to 2.17.7. The issue is due to improper neutralization of input in the data-caption HTML attribute, allowing authenticated users with Contributor-level or higher privileges to inject arbitrary web scripts. These scripts execute when other users access the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS 3.1 base score of 6.4, reflecting a medium severity with network attack vector, low attack complexity, and no user interaction required. No patch or official fix is currently documented.
Potential Impact
Successful exploitation allows authenticated users with Contributor-level access or above to inject persistent malicious scripts into pages via the data-caption attribute. This can lead to execution of arbitrary scripts in the context of other users viewing the affected pages, potentially resulting in information disclosure or session compromise. The impact is limited to confidentiality and integrity with no direct availability impact. No known active exploits have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the data-caption attribute if possible. Monitor for updates from the averta vendor or WordPress theme repository regarding patches or mitigations.
