The EPSS score is below 1\u202f%, suggesting a low but non\u2011zero likelihood of exploitation, and the vulnerability is not currently listed in CISA\u2019s Known Exploited Vulnerabilities catalog. Exploitation would require an attacker to influence the webhook configuration or trigger the cron job, allowing the application to issue unintended requests to internal resources. The lack of SSRF controls is the primary attack vector, and no additional preconditions are noted in the available information."}}}}, "created": "2026-02-23T14:32:05.134916+00:00", "updated": "2026-04-17T17:00:10.144382+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$openclaw"]}
