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-2023-44813 is a reflected cross-site scripting vulnerability (CWE-79) affecting mooSocial version 3.1.8. The flaw resides in the invite friend login function, where the mode parameter fails to sanitize user-supplied input, enabling a remote attacker to supply a crafted payload that executes JavaScript in the context of another user’s session. The issue carries a CVSS 3.1 base score of 6.1 with network attack vector, low complexity, no required privileges, and required user interaction.

An unauthenticated remote attacker can exploit the vulnerability by delivering a malicious link or request containing the crafted mode parameter. Successful exploitation results in script execution that can read limited sensitive data or perform actions within the victim’s browser session, with the changed scope indicating impact beyond the vulnerable component itself.

The EPSS score for this CVE rose from a low baseline to a peak of 0.3780 on 2025-12-11 before receding to the current value of 0.2079, indicating a period of increased exploitation interest after public disclosure. Public references consist of proof-of-concept repositories demonstrating the payload but contain no vendor advisory or patch information.

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.

CA-8 Penetration Testing
addresses: CWE-79

Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.

SI-10 Information Input Validation
addresses: CWE-79

Validates web inputs to reject script-related content that could produce XSS.

SI-15 Information Output Filtering
addresses: CWE-79

Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.

PR.PS-06 mostly match
blocks

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).

PR.PS-02 partial match
blocks

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).
