Attackers can close the inline script string literal with a crafted payload that executes in the browser of every visitor to the affected public booking page, enabling session cookie theft, forged authenticated requests, and wormable propagation by chaining with CSRF-able endpoints to persist payloads on additional events.","publishedAt":"2026-08-12T13:17:22","lastModifiedAt":"2026-08-13T16:18:08","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-57858","cvssScore":8.9,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:L","epssProbability":0.0037,"riskScore":0.92,"affectedProduct":"Cal.com","affectedVersions":">=2.1.1,<=6.2.0","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-57858","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-57858","en":"https://www.redsauce.net/en/cves/CVE-2026-57858","fr":"https://www.redsauce.net/fr/cves/CVE-2026-57858","pt":"https://www.redsauce.net/pt/cves/CVE-2026-57858","de":"https://www.redsauce.net/de/cves/CVE-2026-57858","sk":"https://www.redsauce.net/sk/cves/CVE-2026-57858","el":"https://www.redsauce.net/el/cves/CVE-2026-57858"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-57858"}}
