Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 34% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-5244 is a reflected cross-site scripting vulnerability, tracked as CWE-79, that affects the microweber/microweber GitHub repository in versions prior to 2.0. The flaw carries a CVSS 3.1 base score of 6.1 with a vector of AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, indicating a network-reachable issue that requires no authentication but does need user interaction and produces changed scope.
An unauthenticated remote attacker can supply a crafted URL containing malicious JavaScript that is reflected back to a victim; when the victim follows the link, the script executes in the context of the Microweber application, allowing limited theft or manipulation of data visible to that user session.
Public references point to a specific commit (1cb846f8f54ff6f5c668f3ae64dd81740a7e8968) that resolves the issue, and the associated huntr.dev bounty entry confirms the fix is included in the 2.0 release; administrators should therefore upgrade to version 2.0 or later to eliminate the exposure.
The EPSS score has remained flat at a peak and current value of 0.2893 with no reported real-world exploitation.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.
Validates web inputs to reject script-related content that could produce XSS.
Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
Mitigating Controls (NIST CSF 2.0) AI
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 SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).
Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.5.6 only promotes membership in groups to improve knowledge, receive alerts, and share information; it performs no action that stops XSS exploitation (or even the underlying neutralization defect) and is a pure dependency for other controls per the owner's labeling rule.
