Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 38.9th 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-2025-53560 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the Noisa WordPress theme developed by rascals. The flaw enables Object Injection and affects Noisa versions from n/a through 2.6.0.

The vulnerability carries 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). Low-privileged authenticated attackers can exploit it over the network with low complexity and without user interaction, potentially achieving high impacts on confidentiality, integrity, and availability through object injection.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Requires timely flaw remediation, such as patching the Noisa WordPress theme to versions beyond 2.6.0, directly eliminating the deserialization vulnerability.

SI-10 Information Input Validation good match
prevent

Mandates validation of information inputs to block untrusted data from being deserialized in the vulnerable Noisa theme.

SI-16 Memory Protection partial match
prevent

Implements memory protections like ASLR and DEP to hinder exploitation of object injection into remote code execution.
