This is due to missing file type validation and extension filtering on the page_id parameter, combined with a world-readable leaked nonce that bypasses authentication checks. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. This exploit chain requires obtaining the plugin's REST nonce (tenwebio_rest), which is automatically serialized to a world-readable file under wp-content/uploads/ whenever a bulk optimisation batch pauses; because the nonce is generated in a cron/loopback context with a user ID of 0, it is valid for unauthenticated visitors.\nhttps://www.cve.org/CVERecord?id=CVE-2026-108587https://www.wordfence.com/threat-intel/vulnerabilities/id/adfd97cf-8f61-463d-a535-1a61e3c2e134?source=cvehttps://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.5/vendor/10web-utils/tenweb-image-optimizer/src/TenWebIO/Rest.php#L310https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.5/vendor/10web-utils/tenweb-image-optimizer/src/TenWebIO/CompressService.php#L99https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.5/vendor/10web-utils/tenweb-image-optimizer/src/TenWebIO/Utils.php#L161https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.5/vendor/10web-utils/10web-queue/src/TenWebQueue/Traits/QueueRestart.php#L63https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.5/vendor/10web-utils/tenweb-image-optimizer/src/TenWebIO/Rest.php#L99https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.1/vendor/10web-utils/tenweb-image-optimizer/src/TenWebIO/Rest.php#L310https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.1/vendor/10web-utils/tenweb-image-optimizer/src/TenWebIO/CompressService.php#L99https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.1/vendor/10web-utils/tenweb-image-optimizer/src/TenWebIO/Utils.php#L161https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.1/vendor/10web-utils/10web-queue/src/TenWebQueue/Traits/QueueRestart.php#L63https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.1/vendor/10web-utils/tenweb-image-optimizer/src/TenWebIO/Rest.php#L99https://plugins.trac.wordpress.org/changeset/3743299/tenweb-speed-optimizer#wordpress #10web #10WebBooster\u2013Websitespeedoptimization,Cache&PageSpeedoptimizer#CVE_2026_108587#bot", "url": "https://infosec.exchange/users/cve/statuses/117443038897184613"}, {"timestamp": "2026-10-15T05:17:02Z", "date_only": false, "value": "2026-10-15T05:17:02Z", "kind": "other", "label": "Nvd published at", "source": "github \u00b7 GHSA-38RR-WCWH-JGW6", "record": "GHSA-38RR-WCWH-JGW6", "field": "database_specific.nvd_published_at"}, {"timestamp": "2026-10-15T05:17:02.637Z", "date_only": false, "value": "2026-10-15T05:17:02.637", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-108587", "record": "FKIE_CVE-2026-108587", "field": "published"}, {"timestamp": "2026-10-15T06:00:05.846Z", "date_only": false, "value": "2026-10-15T06:00:05.846843Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/stackflag.bsky.social/post/3mxvf37jadx2n", "record": "CVE-2026-108587", "field": "creation_timestamp", "uuid": "35587b16-5ae3-42c5-9d93-308a26f31e06", "content": "CVE-2026-108587 - 10web booster \u2013 website speed optimization, cache & page speed optimizer\nAll versions of the 10Web Booster plugin for WordPress up to 2.34.10 let unauthenticated users upload files through a missing\u2026\n\nToo many irrelevant or confusing CVEs?
