WordPress · Fluentcrm · CVE-2026-7798
**Name of the Vulnerable Software and Affected Versions**
FluentCRM – Email Newsletter, Automation, Email Marketing, Email Campaigns, Optins, Leads, and CRM Solution versions prior to 2.9.88
**Description**
The plugin is susceptible to Blind Server-Side Request Forgery (SSRF), a flaw where an attacker can force the server to make HTTP requests to an arbitrary destination. This can be exploited by unauthenticated attackers via the `SubscribeURL` parameter to query or modify information from internal services. This issue is only exploitable if the SES bounce handling key ` fc bounce key` has not been stored, which occurs when the site is in its default or unconfigured state regarding SES bounce handling. If the bounce configuration page is visited, a random key is generated and stored, which prevents unauthenticated requests.
**Recommendations**
Update to a version newer than 2.9.87.
As a temporary mitigation, ensure the SES bounce configuration page is visited to generate and store the ` fc bounce key`.
