The application renders LLM\u2011generated captions via an unsafe custom markdown rule that inserts the image alt text directly into an HTML attribute without encoding. Although most rendering paths are protected by DOMPurify, the Chartable component bypasses this safeguard, allowing attacker\u2011controlled content to be stored and later executed in any user\u2019s browser. The flaw can lead to arbitrary JavaScript execution, enabling attackers to steal session data, deface the interface, or perform further malicious actions within the victim\u2019s environment.", "risk_and_exploitability": "The CMS approach yields a CVSS score of 5.4, classifying the vulnerability as moderate severity. The EPSS score of less than 1% indicates a low but non\u2011zero likelihood that this flaw will be actively exploited in the wild, and the vulnerability is not currently listed in the CISA KEV catalog. Exploitation requires an attacker to influence the LLM\u2019s output\u2014most cheaply via prompt injection in a shared document or by creating a chart record in a multi\u2011user workspace\u2014so while the attack vector is relatively low effort, it also requires some level of collaboration or co\u2011editorship access to the workspace. Overall, the risk is moderate but defensible, especially for environments with shared workspaces or permissive LLM prompts."}}}}, "created": "2026-04-27T21:00:11.943634+00:00", "updated": "2026-04-28T14:30:33.765361+00:00", "vendors": ["mintplexlabs", "mintplexlabs$PRODUCT$anything-llm"]}
