This leads to a device being inadvertently exposed and increased CPU cycles spent processing ingress packets.\n\nThis issue affects Junos OS Evolved:\n\n\n  *  all versions before 23.2R2-S7-EVO,\n  *  23.4 versions before 23.4R2-S8-EVO,\n  *  24.2 versions before 24.2R2-S5-EVO,\n  *  24.4 versions before 24.4R2-S4-EVO,\n  *  25.2 versions before 25.2R2-S1-EVO,\n  *  25.4 versions before 25.4R1-S2-EVO.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/AU:Y/R:U/RE:M","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","score":6.5},"cwes":["CWE-923"],"references":["https://supportportal.juniper.net/JSA110078"],"products":["juniper:junos_os_evolved"],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-33803","score":0.00353,"percentile":0.28735,"date":"2026-10-25"},"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).
