Short explanation
In Thelia v2.6.0, the store banner upload feature performs insufficient filetype validation that relies exclusively on client-supplied MIME types. An administrative attacker can upload a disguised PHP file to achieve remote code execution on the underlying server.
This vulnerability can yield severe consequences because successful exploitation allows an attacker to execute remote code on the underlying server. Relying solely on client-supplied data for validation introduces significant exposure.
What should be done?
- Follow vendor advisories
- Strengthen file upload validations on the server side
- Ensure MIME type checks do not rely solely on client input
