Instapage Plugin
Monthly
Unauthenticated server-side request forgery in the Instapage WordPress plugin, affecting all versions up to and including 3.7.2, lets any remote attacker who can reach a vulnerable site make the web server issue requests to arbitrary internal or external destinations. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N, base 7.2) confirms the attack is network-reachable, requires no credentials and no user interaction, and crosses a security scope boundary, though the Low confidentiality and Low integrity ratings indicate constrained response retrieval and limited write effects rather than full data exfiltration. No public exploit code or in-the-wild exploitation has been identified at time of analysis, and no EPSS or KEV data was supplied; this is a medium-to-high severity, lower-urgency issue whose practical impact depends on what internal services, cloud metadata endpoints, or trusted-network resources are reachable from the affected web server.
