{"apiVersion":"1.0","identifier":"CVE-2026-65610","description":"nnn stores homelen variable as uchar_t, which can only represent values in the range 0-255. An attacker who can influence the victim-s execution environment can provide an arbitrary HOME path with length that is truncated to 0. The expression (homelen - 1) is promoted to signed int and becomes -1 and producing an out-of-bounds read and an out-of-bounds write one byte before the path buffer. Maintainer of this project was notified about this vulnerability. It might has been addressed, but the maintainer did not provide a vulnerable version range. Only version 5.2 was tested and confirmed as vulnerable.","publishedAt":"2026-08-19T14:17:38","lastModifiedAt":"2026-08-28T15:26:19","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-65610","cvssScore":2.4,"cvssVector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00123,"riskScore":0.24,"affectedProduct":"nnn","affectedVersions":"unknown","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-65610","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-65610","en":"https://www.redsauce.net/en/cves/CVE-2026-65610","fr":"https://www.redsauce.net/fr/cves/CVE-2026-65610","pt":"https://www.redsauce.net/pt/cves/CVE-2026-65610","de":"https://www.redsauce.net/de/cves/CVE-2026-65610","sk":"https://www.redsauce.net/sk/cves/CVE-2026-65610","el":"https://www.redsauce.net/el/cves/CVE-2026-65610"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-65610"}}
