Unauthenticated Cross Site Scripting (XSS) in SureCart <= 4.3.2 versions.
AnalysisAI
Reflected cross-site scripting in the SureCart WordPress e-commerce plugin (versions 4.3.2 and earlier) lets unauthenticated remote attackers inject browser-executed script by luring a victim to a crafted link. Because the CVSS scope is changed (S:C), the injected payload can act in the security context of the WordPress session, enabling theft of admin session data or actions performed on the victim's behalf. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires victim interaction (UI:R): the attacker cannot trigger it server-side alone but must convince a user - ideally an authenticated WordPress administrator - to open a crafted link or load a malicious request against a site running SureCart 4.3.2 or earlier. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.1 reflects a network attack vector with low complexity and no privileges required, but exploitation is gated on user interaction (UI:R) - a victim must click or load the malicious link - and impact is limited (C:L/I:L/A:L), elevated to 7.1 only by the scope change (S:C). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a URL to a SureCart-powered store containing a malicious script payload in a reflected parameter and distributes it via phishing email, social media, or a malicious ad. When a logged-in store administrator or customer clicks the link, the script executes in their browser session, allowing the attacker to steal session data, perform actions as the victim, or stage further attacks. … |
| Remediation | Upgrade SureCart to a release later than 4.3.2 - the advisory frames 4.3.2 as the last vulnerable version, so administrators should apply the next available patched release from the WordPress plugin repository and verify the installed version after updating; no exact fixed version number was included in the provided data, so confirm the patched version against the vendor/Patchstack advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Disable the SureCart plugin on all affected installations (version 4.3.2 and earlier) or restrict administrative dashboard access to internal IP ranges pending patch availability; audit session logs for unauthorized access. …
