AI-Generated

Affected versions of Flowintel (3.3.0 and above) have a vulnerability that allows an attacker with permission to create or edit case notes to inject malicious Mermaid payloads, leading to potential JavaScript execution when other users view the notes. This could result in unauthorized actions or data exposure for users interacting with the compromised notes. Organizations utilizing Flowintel should prioritize patching this vulnerability to safeguard against potential exploitation.

Original NVD Description

Affected versions of Flowintel render Mermaid blocks contained in stored case notes without sufficiently neutralizing attacker-controlled markup. Because Mermaid note content is persisted and later rendered for other users, an attacker with permission to create or edit a note could store a crafted Mermaid payload that results in JavaScript execution when another user views the affected case note. The patch adds explicit Mermaid detection and HTML escaping around the token content before the generated Mermaid wrapper is returned. It also moves the wrapping logic earlier in page initialization so Markdown instances are protected consistently. Version impacted >= 3.3.0
