As a result, reactions created by non\u2011allowlisted members are accepted as trusted events and their reaction text is injected into the bot\u2019s downstream session context. This enables malicious actors to alter session data, potentially leading to unintended command execution, data manipulation, or the spread of spam or malicious content within the guild\u2019s context.", "risk_and_exploitability": "The CVSS score of 5.3 indicates a medium impact assessment. No EPSS score is available and the vulnerability is not listed in the CISA KEV catalog, suggesting no known widespread exploitation. Likely attackers would need to be a member of the target guild; by sending a crafted reaction to a channel the bot monitors, they can trigger the vulnerable code path and inject payloads as part of the session context. Exploitability is moderate, requiring only access to the guild\u2019s Discord interface rather than system-level privileges."}}}}, "created": "2026-03-29T20:31:33.077918+00:00", "updated": "2026-03-30T06:58:23.135341+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$openclaw"]}
