{"apiVersion":"1.0","identifier":"CVE-2026-70453","description":"rsync before 3.5.0 contains an algorithmic complexity vulnerability in the hash_search() function that allows a remote attacker to cause a denial of service by delivering a carefully constructed file list. A sender can exploit the quadratic-time worst-case behavior in hash lookups to exhaust receiver CPU resources with a modest number of crafted entries, causing a sustained denial of service.","publishedAt":"2026-08-13T15:19:58","lastModifiedAt":"2026-08-13T18:18:15","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-70453","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00525,"riskScore":0.79,"affectedProduct":"rsync","affectedVersions":"<3.5.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-70453","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-70453","en":"https://www.redsauce.net/en/cves/CVE-2026-70453","fr":"https://www.redsauce.net/fr/cves/CVE-2026-70453","pt":"https://www.redsauce.net/pt/cves/CVE-2026-70453","de":"https://www.redsauce.net/de/cves/CVE-2026-70453","sk":"https://www.redsauce.net/sk/cves/CVE-2026-70453","el":"https://www.redsauce.net/el/cves/CVE-2026-70453"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-70453"}}
