This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable because a comment author Name value containing ' src=' and an event-handler payload contains no HTML tags or quote characters, allowing it to survive WordPress core's sanitize_text_field and land verbatim inside the alt attribute, where the plugin's own str_replace subsequently injects the single quote that breaks out of the attribute context.","state":0,"publishedAt":"2026-10-10T06:40:15.105+00:00","modifiedAt":"2026-10-11T12:13:45.257+00:00","affected":[{"ecosystem":"Vendor product","name":"10Web Booster – Website speed optimization, Cache & Page Speed optimizer","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"10web\",\n                    \"product\": \"10Web Booster – Website speed optimization, Cache & Page Speed optimizer\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"2.34.8\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/b14945a5-c5e7-45cb-b2cc-8d1a265b6c52?source=cve","https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.8/includes/OptimizerImages.php#L445","https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.8/includes/OptimizerImages.php#L310","https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.8/includes/OptimizerImages.php#L186","https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.8/tenweb_speed_optimizer.php#L175","https://plugins.trac.wordpress.org/browser/tenweb-speed-optimizer/tags/2.34.10"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107742","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107742","identifiers":["CVE-2026-107742"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
