Security readout for executives and security teams
Plain-English summary
This is a cross-site scripting issue in jQuery UI Datepicker before 1.13.0. If an application feeds untrusted values into Datepicker label-style *Text options, a user could be exposed to attacker-controlled script in the browser. Business urgency is moderate and depends on whether affected Datepicker options are reachable from user-controlled data.
Executive priority
Treat this as a moderate web application remediation item. It is not documented as actively exploited in the provided sources, but it can affect public sites and downstream platforms. Prioritize systems where non-admin users, customers, or content editors can influence Datepicker labels.
Technical view
CVE-2021-41183 is CWE-79 in jquery-ui Datepicker before 1.13.0. The vulnerable *Text options were treated as HTML, allowing untrusted input to execute script. jQuery UI 1.13.0 changed these option values to be handled as pure text. CVSS is 6.5 with network access, low complexity, no privileges, and user interaction required.
Likely exposure
Exposure is likely in applications using jquery-ui earlier than 1.13.0 where Datepicker *Text option values come from users, tenants, CMS content, localization data, or other untrusted sources. Downstream products and distributions referenced Drupal, Fedora, Debian LTS, Oracle, NetApp, and Tenable advisories, so packaged dependencies should also be checked.
Exploitation context
The provided sources do not state active exploitation, and KEV is false. Exploitation requires a user to interact with an affected page where an attacker can influence Datepicker *Text option values. Impact is browser-side integrity compromise rather than server compromise based on the provided CVSS vector.
Researcher notes
The key condition is untrusted control of Datepicker *Text options, not merely having jquery-ui installed. The fix is behavioral: option values are treated as text rather than HTML in 1.13.0. Evidence supports affected jquery-ui versions before 1.13.0, but the bundle does not provide product-specific exploitability details for every downstream advisory.
Mitigation direction
- Upgrade jquery-ui to version 1.13.0 or later.
- Do not accept Datepicker *Text option values from untrusted sources.
- Review downstream vendor advisories for packaged jquery-ui fixes.
- Sanitize or replace dynamic Datepicker labels until upgraded.
- Prioritize internet-facing and tenant-configurable applications first.
Validation and detection
- Inventory jquery-ui versions in package manifests and static assets.
- Search code for Datepicker configuration using *Text options.
- Trace whether those option values can come from untrusted input.
- Confirm production assets load jquery-ui 1.13.0 or later.
- Check Drupal, Fedora, Debian, Oracle, or vendor advisories where applicable.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
