Raw vector
CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:L/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2020-11023 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Oracle Rest Data Services. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 0.3% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2020-11023 is a cross-site scripting vulnerability affecting jQuery versions from 1.0.3 up to but not including 3.5.0. It occurs when HTML containing <option> elements from untrusted sources is passed to DOM manipulation methods such as .html() or .append(), even if the input has been sanitized beforehand, allowing execution of untrusted code. The issue is tracked under CWE-79 and carries a CVSS 3.1 score of 6.9.
An attacker can supply crafted HTML containing <option> tags to an application that uses an affected jQuery version and feeds that input into the vulnerable DOM methods. Successful exploitation can result in execution of arbitrary script in the context of the affected page, potentially leading to theft of sensitive data or other actions within the victim's browser session.
The jQuery project released version 3.5.0 to address the flaw. Multiple openSUSE security advisories reference the update and recommend applying the patched jQuery release to resolve the exposure.

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).

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.
