Under high load and specific timing conditions, an invalid internal state can occur during cleanup of pending WebFiltering lookups, resulting in a crash of the UTM process.\nThis issue applies to both NextGeneration WebFiltering (NGWF) and Enhanced WebFiltering (EWF).\n\nThis issue affects Junos OS on SRX Series:\n\n\n  *  23.2 versions from 23.2R2 before 23.2R2-S7.7;\n  *  23.4 versions from 23.4R2 before 23.4R2-S8.13;\n  *  24.2 versions before 24.2R2-S5.5;\n  *  24.4 versions before 24.4R2-S4;\n  *  25.2 versions before 25.2R2-S1;\n  *  25.4 versions before 25.4R1-S3, 25.4R2.","published":"2026-10-14T17:18:04.000Z","lastModified":"2026-10-15T16:24:19.000Z","status":"Awaiting Analysis","sourceIdentifier":"sirt@juniper.net","cvss":{"version":"4.0","score":8.2,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-413"],"affected":[],"epss":{"score":0.00313,"percentile":0.24001,"date":"2026-10-26","history":[{"date":"2026-10-15","score":0.00313,"percentile":0.22566}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.31%).
