This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Exploitation requires enabling manual minify mode and supplying a manual-format minify filename so that the hash is empty and the f_array[] entries are not overwritten before reaching setupSources().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-22"],"references":["https://plugins.trac.wordpress.org/browser/w3-total-cache/tags/2.9.4/Minify_MinifiedFileRequestHandler.php#L191","https://plugins.trac.wordpress.org/browser/w3-total-cache/tags/2.9.4/Minify_Plugin.php#L132","https://plugins.trac.wordpress.org/browser/w3-total-cache/tags/2.9.4/lib/Minify/Minify/Controller/MinApp.php#L109","https://plugins.trac.wordpress.org/browser/w3-total-cache/tags/2.9.4/lib/Minify/Minify/Controller/MinApp.php#L163","https://plugins.trac.wordpress.org/changeset?reponame=&old=3585227%40w3-total-cache&new=3585227%40w3-total-cache"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-9282","score":0.02861,"percentile":0.86756,"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).
