The impacts can be many, and vary from the theft of information and credentials to the redirection to malicious websites containing attacker-controlled content, which in some cases even cause XSS attacks. So even though an open redirection might sound harmless at first, the impacts of it can be severe should it be exploitable. The problem is fixed in 1.7.6.5","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-601"],"references":["https://github.com/PrestaShop/PrestaShop/commit/cd2219dca49965ae8421bb5a53fc301f3f23c458","https://github.com/PrestaShop/PrestaShop/security/advisories/GHSA-375w-q56h-h7qc","https://github.com/PrestaShop/PrestaShop/commit/cd2219dca49965ae8421bb5a53fc301f3f23c458","https://github.com/PrestaShop/PrestaShop/security/advisories/GHSA-375w-q56h-h7qc"],"products":["prestashop:prestashop"],"source":"nvd","synced_at":"2026-10-19T21:04:18.695612450+00:00"},"epss":{"cve":"CVE-2020-5270","score":0.00832,"percentile":0.57642,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
