{"apiVersion":"1.0","identifier":"CVE-2026-80195","description":"Kimai before 2.63.0 contains a business logic / improper authorization vulnerability in the team update API endpoint (PATCH /api/teams/{id}), which removes all existing team members before validating the submitted replacement member list. An authenticated teamlead (or other user) with permission to edit a team can submit a malformed members payload; although Kimai returns a validation error, the existing membership rows have already been deleted. This bypasses the dedicated member-removal endpoint-s protection against removing teamleaders and can leave a team with no members or teamleaders, disrupting team-based access control.","publishedAt":"2026-08-26T05:18:26","lastModifiedAt":"2026-08-26T17:17:25","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80195","cvssScore":5.4,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","epssProbability":0.00276,"riskScore":0.55,"affectedProduct":"Kimai","affectedVersions":"<2.63.0","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80195","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80195","en":"https://www.redsauce.net/en/cves/CVE-2026-80195","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80195","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80195","de":"https://www.redsauce.net/de/cves/CVE-2026-80195","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80195","el":"https://www.redsauce.net/el/cves/CVE-2026-80195"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80195"}}
