Unauthenticated Cross Site Scripting (XSS) in Landing Page Builder <= 1.5.3.5 versions.
AnalysisAI
Cross-site scripting in the PluginOps Landing Page Builder WordPress plugin (versions <= 1.5.3.5) lets unauthenticated remote attackers inject script that executes in a victim's browser, with a scope change (S:C) indicating the payload can affect resources beyond the vulnerable component. The flaw requires victim interaction (UI:R) such as visiting a crafted link or page, and yields low-level confidentiality, integrity, and availability impact (CVSS 7.1). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires no authentication (PR:N) but does require victim interaction (UI:R) - the target must visit an attacker-crafted page or click a malicious link that triggers the unsanitized input rendering in the PluginOps Landing Page Builder plugin (<= 1.5.3.5). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score is 7.1 (High) with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L: network-reachable, low complexity, no privileges required, but mandatory user interaction tempers automatability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious URL or input targeting the vulnerable Landing Page Builder endpoint and lures a victim - a site visitor or logged-in administrator - into visiting it. When the page renders the unsanitized input, attacker-controlled JavaScript executes in the victim's browser, enabling session/cookie theft, redirection, or actions performed as the victim; no public POC was provided in the input. |
| Remediation | No vendor-released patch version is confirmed from the available input data; the advisory only establishes that versions <= 1.5.3.5 are affected, so administrators should consult the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/page-builder-add/vulnerability/wordpress-landing-page-builder-plugin-1-5-3-5-cross-site-scripting-xss-vulnerability) and the WordPress plugin repository for a release newer than 1.5.3.5 and upgrade as soon as one is published. … Detailed patch versions, workarounds, and compensating controls in full report. |
