CVE-2021-39267: Salesagility Suitecrm

Medium severity, CVSS 6.1. EPSS: 2% chance of exploitation in the next 30 days.

Persistent cross-site scripting (XSS) in the web interface of SuiteCRM before 7.11.19 allows a remote attacker to introduce arbitrary JavaScript via a Content-Type Filter bypass to upload malicious files. This occurs because text/html is blocked, but other types that allow JavaScript execution (such as text/xml) are not blocked.

Affected products

• Salesagility Suitecrm: before 7.11.19 (fixed in 7.11.19)
