TinyMCE is an open source rich text editor. Prior to 5.11.1, 7.9.3, and 8.5.1, there is a stored XSS vulnerability via unsanitized data-mce-* attributes (data-mce-href, data-mce-src, data-mce-style). Allows attackers to inject malicious values that override safe attributes during serialization, bypassing validation. This vulnerability is fixed in 5.11.1, 7.9.3, and 8.5.1.

According to its self-reported version number, the Atlassian Jira application running on the remote host is prior to 10.3.25 or 10.4.x prior to 11.3.11. It is, therefore, affected by multiple vulnerabilities, including flaws in bundled third-party dependencies :
