{"apiVersion":"1.0","identifier":"CVE-2026-70454","description":"rsync 3.2.0 through 3.2.3 (openssl mode) and rsync-ssl through 3.4.4 (stunnel mode) contain a TLS certificate validation vulnerability that allows on-path attackers to intercept encrypted sessions by presenting self-signed or otherwise invalid certificates. Attackers can exploit the failure to validate server TLS certificates against a trusted CA or verify certificate hostname matching to decrypt or tamper with rsync session content without detection by the client.","publishedAt":"2026-08-13T15:19:59","lastModifiedAt":"2026-08-13T16:19:01","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-70454","cvssScore":8,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:N","epssProbability":0.0019,"riskScore":0.81,"affectedProduct":"rsync","affectedVersions":">=3.2.0,<=3.2.3,>=3.4.0,<=3.4.4","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-70454","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-70454","en":"https://www.redsauce.net/en/cves/CVE-2026-70454","fr":"https://www.redsauce.net/fr/cves/CVE-2026-70454","pt":"https://www.redsauce.net/pt/cves/CVE-2026-70454","de":"https://www.redsauce.net/de/cves/CVE-2026-70454","sk":"https://www.redsauce.net/sk/cves/CVE-2026-70454","el":"https://www.redsauce.net/el/cves/CVE-2026-70454"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-70454"}}
