jQuery-UI is the official jQuery user interface library. Prior to version 1.13.0, accepting the value of the of option of the .position() util from untrusted sources may execute untrusted code. The issue is fixed in jQuery UI 1.13.0. Any string value passed to the of option is now treated as a CSS selector. A workaround is to not accept the value of the of option from untrusted sources.
CVE-2021-41184
Score elevated to 6.7 because EPSS predicts 41% probability of exploitation within the next 30 days (top 1.5% of all CVEs). NVD baseline CVSS 6.1 retained for reference. Confidence: see factors.
