Based on the description, it is inferred that an attacker would need only to host a malicious page that the victim visits, and the victim\u2019s browser would then forge the requests. The flaw maps to the classic cross\u2011site request forgery weakness (CWE\u2011352), and the primary impact is local state manipulation that can disrupt the user\u2019s browsing experience.", "risk_and_exploitability": "The CVSS score of 7.1 indicates a high impact with moderate to high exploitability. The EPSS score of <\u202f1\u202f% suggests that exploitation is unlikely at present. The flaw is not listed in the CISA KEV catalog. Attackers would need only a malicious web page; the victim\u2019s browser would then forge requests to the loopback mutation endpoints, bypassing the lack of Origin/Referer validation. The combination of low EPSS and high CVSS underscores the importance of promptly applying the vendor\u2019s patch or enabling authentication."}}}}, "created": "2026-02-20T09:53:50.914212+00:00", "updated": "2026-04-18T11:45:44.599232+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$clawdbot", "openclaw$PRODUCT$openclaw"]}
