Camaleon CMS before 2.9.3 contains a path traversal vulnerability that allows users with only the media permission to write arbitrary files by supplying ../ sequences in the name parameter. Attackers can send a base64 data: URI to the crop_url media action to write an ERB template into a theme's views directory, which executes when rendered.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
