Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
This CVE describes a server-side request forgery (SSRF) flaw, tracked as CWE-918, in the PaperCut NG/MF server-side module. The vulnerability permits an unauthenticated remote attacker to cause the application to issue HTTP requests to arbitrary attacker-chosen domains, carrying a CVSS 3.1 score of 6.5.
An attacker with network access can exploit the issue without credentials or user interaction, achieving limited disclosure of internal resources and limited ability to interact with internal or external systems reachable by the PaperCut server.
PaperCut’s March 2024 security bulletin provides official guidance and remediation steps for affected customers.
EPSS for the CVE rose from a low baseline to a peak of 0.4038 on 2025-12-11 before receding, indicating a clear post-disclosure increase in exploitation interest.

Mitigating Controls (NIST 800-53 r5) AI
Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.
Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.
Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure development practices directly include input validation and destination allow-listing that prevent SSRF.
Runtime monitoring of web applications and services can detect anomalous outbound requests indicative of SSRF.
Vulnerability identification processes can discover and record SSRF flaws in web applications.
Network segmentation and egress controls can limit the damage from successful SSRF requests.
