1Presentation about CVE-2025-55746https://github.com/r4bbit-r4/directus-presoPOC Details
2Directus versions from 10.8.0 before 11.9.3 allow unauthenticated attackers to modify the contents of an existing file when a valid file UUID is known. The PATCH /files/{id} endpoint processes multipart file uploads without proper authentication, allowing file content replacement despite returning a 403 status code. This template requires a known, controlled Directus file UUID provided via the file_id variable. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2025/CVE-2025-55746.yamlPOC Details
