CVE-2024-2657 is a medium-severity Improper Neutralization of Alternate XSS Syntax (CWE-87) vulnerability in Wordpress (inferred from references). Its CVSS base score is 4.4 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Content Injection (T1659); ranked at the 17th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data
The Font Farsi plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.6.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level…

permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
SA-11 requires developer testing and analysis that can discover improper neutralization of alternate script syntax after it has been coded.
SI-10 directly requires validation/sanitization of untrusted inputs, which structurally stops alternate XSS syntax from reaching the interpreter.
SA-8 mandates secure engineering principles such as input neutralization and output encoding that prevent introduction of this class of flaw.

Secure SDLC practices directly require proper input neutralization and output encoding to prevent alternate XSS syntax.

Secure coding standards require proper neutralization of alternate script syntax, directly eliminating CWE-87.
Security testing catches residual XSS but does not itself implement the neutralization controls.
Secure SDLC mandates input validation and output encoding that directly prevent alternate XSS syntax.
Application security requirements explicitly call for neutralization of untrusted input to block XSS variants.
Secure architecture principles reduce attack surface but do not prescribe specific encoding rules.
