The vulnerability CVE-2025-31840 involves a CSRF issue in the Simple Fixed Notice plugin by digireturn, specifically in the dn-cookie-notice component. Versions up to 1.6 are affected. The vulnerability allows attackers to trick authenticated users into submitting unauthorized requests, potentially causing limited impact on the integrity of the application. The CVSS vector indicates the attack can be performed remotely without privileges but requires user interaction. Confidentiality and availability impacts are not present, with only a low impact on integrity.

The impact is limited to a low integrity impact due to the CSRF vulnerability. There is no confidentiality or availability impact reported. The vulnerability could allow an attacker to perform certain actions on behalf of an authenticated user without their consent, but the overall severity is medium due to the limited scope of impact and requirement for user interaction.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor the vendor's communications for updates. In the meantime, applying standard CSRF mitigations such as verifying anti-CSRF tokens in requests or disabling the vulnerable plugin if feasible may reduce risk.
