{"apiVersion":"1.0","identifier":"CVE-2026-3129","description":"The LiteSpeed Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via crafted `<img>` tag attributes in all versions up to, and including, 7.7. This is due to a flawed regular expression that is used to strip `width` and `height` attributes from images when the -Lazy Load Images- and -Add Missing Sizes- features are enabled. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that execute whenever a user accesses an injected page.","publishedAt":"2026-08-28T05:16:42","lastModifiedAt":"2026-08-28T15:09:00","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-3129","cvssScore":6.4,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","epssProbability":0.00187,"riskScore":0.65,"affectedProduct":"LiteSpeed Cache","affectedVersions":"<=7.7","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-3129","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-3129","en":"https://www.redsauce.net/en/cves/CVE-2026-3129","fr":"https://www.redsauce.net/fr/cves/CVE-2026-3129","pt":"https://www.redsauce.net/pt/cves/CVE-2026-3129","de":"https://www.redsauce.net/de/cves/CVE-2026-3129","sk":"https://www.redsauce.net/sk/cves/CVE-2026-3129","el":"https://www.redsauce.net/el/cves/CVE-2026-3129"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-3129"}}
