Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-15540 is a code injection vulnerability (CWE-94) in the "Functions" module of Raytha CMS. This module enables privileged users to write custom JavaScript code to extend application functionality. Due to a lack of sandboxing or access restrictions, such JavaScript executed through the Functions feature can instantiate .NET components and perform arbitrary operations within the application's hosting environment. 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).

Attackers with low privileges, such as authenticated users granted access to the Functions module, can exploit this over the network with low complexity and no user interaction required. By injecting malicious JavaScript, they can leverage .NET component instantiation to execute arbitrary code in the hosting environment, resulting in high impacts to confidentiality, integrity, and availability, potentially leading to full server compromise.

The vulnerability was fixed in Raytha CMS version 1.4.6. Additional mitigation details are available in the advisory at https://cert.pl/en/posts/2026/03/CVE-2025-69236 and on the vendor site at https://raytha.com.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
