CVE-2022-48110

Status: ModifiedMedium (6.1)—💥 Exploit

CKSource CKEditor 5 35.4.0 was discovered to contain a cross-site scripting (XSS) vulnerability via the Full Featured CKEditor5 widget. NOTE: the vendor's position is that this is not a vulnerability. The CKEditor 5 documentation discusses that it is the responsibility of an integrator (who is adding CKEditor 5 functionality to a website) to choose the correct security settings for their use case. Also, safe default values are established (e.g., config.htmlEmbed.showPreviews is false).

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
