This could lead to spoofing the browser UI if the sudden appearance of the prompt distracted the user from noticing the visual transition happening behind the prompt. These notifications now use the Android Toast feature. \n*This bug only affects Firefox on Android. Other operating systems are unaffected.* This vulnerability affects Firefox < 130.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-1021"],"references":["https://bugzilla.mozilla.org/buglist.cgi?bug_id=1839074%2C1865413%2C1868970%2C1873367%2C1877820%2C1884642%2C1886469%2C1894326%2C1894891%2C1897648","https://bugzilla.mozilla.org/show_bug.cgi?id=1902996","https://www.mozilla.org/security/advisories/mfsa2024-39/"],"products":["mozilla:firefox"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2024-8388","score":0.00362,"percentile":0.30077,"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).
