CVE-2026-9282HIGH | W3 Total Cache <= 2.9.4 - Unauthenticated Arbitrary File Read via 'f_array[]' ParameterThe W3 Total Cache plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.9.4 via the setupSources function. 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(). | CVSS7.5v3.1 | EPSS2.77% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware use1 Nuclei template | STIX |

CVE-2026-5032HIGH | W3 Total Cache <= 2.9.3 - Unauthenticated Security Token Exposure via User-Agent HeaderThe W3 Total Cache plugin for WordPress is vulnerable to information exposure in all versions up to, and including, 2.9.3. This is due to the plugin bypassing its entire output buffering and processing pipeline when the request's User-Agent header contains "W3 Total Cache", which causes raw mfunc/mclude dynamic fragment HTML comments — including the W3TC_DYNAMIC_SECURITY security token — to be rendered in the page source. This makes it possible for unauthenticated attackers to discover the value… CWE-200Apr 2, 2026 | CVSS7.5v3.1 | EPSS0.956% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |

This makes it possible for unauthenticated attackers to view potentially sensitive information in the exposed log file. For example, the log file may contain nonce values that can be used in further CSRF attacks. Note: the debug feature must be enabled for this to be a concern, and it is disabled by default. | CVSS5.3v3.1 | EPSS2.27% | PoCs1 | SignalsNot listed in CISA KEVNo known ransomware use1 Nuclei template | STIX |
