{"apiVersion":"1.0","identifier":"CVE-2026-53793","description":"rsync before 3.5.0 contains a path confinement bypass vulnerability that allows remote clients to escape the intended inner-module root confinement by constructing paths that resolve outside the chroot boundary when the module root contains a /./ boundary marker. Attackers can exploit improper handling of the /./ notation or forge delta-basis transfers referencing xname paths that cross the /./ boundary to gain unauthorized read or write access to files outside the module-s subtree.","publishedAt":"2026-08-13T15:19:43","lastModifiedAt":"2026-08-14T16:16:56","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53793","cvssScore":7.4,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","epssProbability":0.00393,"riskScore":0.77,"affectedProduct":"rsync","affectedVersions":"<3.5.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53793","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53793","en":"https://www.redsauce.net/en/cves/CVE-2026-53793","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53793","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53793","de":"https://www.redsauce.net/de/cves/CVE-2026-53793","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53793","el":"https://www.redsauce.net/el/cves/CVE-2026-53793"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53793"}}
