CVE intelligence and bounded remediation
CVE-2025-55040 — Murasoftware Mura Cms security vulnerability
The import form CSRF vulnerability in MuraCMS through 10.1.10 allows attackers to upload and install malicious form definitions through a CSRF attack. The vulnerable cForm.importform function lacks CSRF token validation, enabling malicious websites to forge file upload requests that install attacker-controlled forms when an authenticated administrator visits a crafted webpage. Full exploitation of this vulnerability would require the victim to select a malicious ZIP file containing form definitions, which can be automatically generated by the exploit page and used to create data collection forms that steal sensitive information. Successful exploitation of the import form CSRF vulnerability could result in the installation of malicious data collection forms on the target MuraCMS website that can steal sensitive user information. When an authenticated administrator visits a malicious webpage containing the CSRF exploit and selects the attacker-generated ZIP file, their browser uploads and installs form definitions that create legitimate forms that could be designed with malicious content.

Information disclosure and sensitive data exposure
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
- Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
- Review metadata, timing, status, length, and existence signals as well as direct content disclosure.
Remediate safely
- Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
- Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
- Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
