This makes it possible for unauthenticated attackers to create arbitrary directories (mode 0777, recursively) outside the cache root and write a cached page into them. The write is LIMITED: the filename is always 'source.html', so the extension is fixed, and the content is the rendered page buffer rather than attacker-supplied data. PHP files cannot be written and code execution is not possible; the demonstrated impact is cache poisoning and arbitrary directory creation.\nhttps://www.cve.org/CVERecord?id=CVE-2026-103896https://www.wordfence.com/threat-intel/vulnerabilities/id/83e672e7-2483-46e9-ae16-a9e7ccc4bcb8?source=cvehttps://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.5/includes/WebPageCache/OptimizerWebPageCache.php#L205https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.5/includes/WebPageCache/OptimizerWebPageCache.php#L190https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.5/includes/WebPageCache/OptimizerWebPageCache.php#L312https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.5/includes/WebPageCache/OptimizerWebPageValidations.php#L299https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.8#wordpress #10web #10WebBooster\u2013Websitespeedoptimization,Cache&PageSpeedoptimizer#CVE_2026_103896#bot", "url": "https://infosec.exchange/users/cve/statuses/117448979801039030"}, {"timestamp": "2026-10-16T06:17:03Z", "date_only": false, "value": "2026-10-16T06:17:03Z", "kind": "other", "label": "Nvd published at", "source": "github \u00b7 GHSA-GPM8-99Q9-V8FC", "record": "GHSA-GPM8-99Q9-V8FC", "field": "database_specific.nvd_published_at"}, {"timestamp": "2026-10-16T06:17:03.417Z", "date_only": false, "value": "2026-10-16T06:17:03.417", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-103896", "record": "FKIE_CVE-2026-103896", "field": "published"}, {"timestamp": "2026-10-16T06:30:27Z", "date_only": false, "value": "2026-10-16T06:30:27Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-GPM8-99Q9-V8FC", "record": "GHSA-GPM8-99Q9-V8FC", "field": "published"}, {"timestamp": "2026-10-16T06:30:27Z", "date_only": false, "value": "2026-10-16T06:30:27Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-GPM8-99Q9-V8FC", "record": "GHSA-GPM8-99Q9-V8FC", "field": "modified"}, {"timestamp": "2026-10-16T14:55:48.533Z", "date_only": false, "value": "2026-10-16T14:55:48.533241Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-103896", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-16T14:55:48.533Z", "date_only": false, "value": "2026-10-16T14:55:48.533241Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-103896", "record": "FKIE_CVE-2026-103896", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2026-10-16T15:09:39.142Z", "date_only": false, "value": "2026-10-16T15:09:39.142Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-103896", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-16T15:09:39.142Z", "date_only": false, "value": "2026-10-16T15:09:39.142Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-103896", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-16T15:17:02.663Z", "date_only": false, "value": "2026-10-16T15:17:02.663", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-103896", "record": "FKIE_CVE-2026-103896", "field": "lastModified"}]}
