{"apiVersion":"1.0","identifier":"CVE-2026-52886","description":"Notepad++ is a free and open-source source code editor. Prior to 8.9.7, Notepad++ validates the backupFilePath attribute from session.xml with std::wstring::starts_with against the expected backup directory without path normalization, allowing parent-directory sequences during snapshot-mode restoration to read an arbitrary user-readable file outside the backup directory into an editor tab. This issue is fixed in version 8.9.7.","publishedAt":"2026-08-17T20:16:44","lastModifiedAt":"2026-08-18T16:17:42","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-52886","cvssScore":5.1,"cvssVector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:H/VI:N/VA:N/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":0.00238,"riskScore":0.52,"affectedProduct":"Notepad++","affectedVersions":"<8.9.7","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-52886","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-52886","en":"https://www.redsauce.net/en/cves/CVE-2026-52886","fr":"https://www.redsauce.net/fr/cves/CVE-2026-52886","pt":"https://www.redsauce.net/pt/cves/CVE-2026-52886","de":"https://www.redsauce.net/de/cves/CVE-2026-52886","sk":"https://www.redsauce.net/sk/cves/CVE-2026-52886","el":"https://www.redsauce.net/el/cves/CVE-2026-52886"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-52886"}}
