Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 40.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-60947 is an arbitrary file upload vulnerability affecting Census CSWeb version 8.0.1. Published on 2026-03-23, it is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). The flaw enables a remote, authenticated attacker to upload a malicious file, potentially resulting in remote code execution.
A remote attacker with low-privilege authenticated access can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation grants high-impact access to confidentiality, integrity, and availability, allowing the attacker to execute arbitrary code on the server by uploading and triggering a malicious file.
Mitigation is available in Census CSWeb 8.1.0 alpha, as indicated by the patching commit at https://github.com/csprousers/csweb/commit/eba0b59a243390a1a4f9524cce6dbc0314bf0d91. Additional resources include a CISA advisory at https://raw.githubusercontent.com/cisagov/CSAF/develop/csaf_files/IT/white/2026/va-26-082-01.json, the official CVE record at https://www.cve.org/CVERecord?id=CVE-2025-60947, and an exploits repository at https://github.com/hx381/cspro-exploits. Security practitioners should upgrade to the fixed version and review access controls for file upload functionalities.
