xipblog module v2.0.1 and before for PrestaShop allows unauthenticated remote attackers to inject arbitrary JavaScript via the name and content parameters in ajax.php. The input is stored in the database without HTML sanitization and rendered in Smarty templates without output escaping, resulting in Stored Cross-Site Scripting (XSS). When an administrator reviews comments in the back office, the payload executes with admin-level session context, leading to full store compromise.
AnalysisAI
Stored Cross-Site Scripting in xipblog v2.0.1 and earlier for PrestaShop allows unauthenticated remote attackers to inject persistent JavaScript payloads through the name and content parameters of ajax.php, which are written to the database without sanitization and rendered unsafely in Smarty templates. When a store administrator subsequently reviews submitted comments in the PrestaShop back office, the payload executes within the admin's authenticated browser session, enabling full store compromise including session hijacking, unauthorized admin actions, and potential exfiltration of customer and payment data. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be able to reach the ajax.php endpoint of the xipblog module over the network, which is expected to be publicly accessible on any PrestaShop installation running this module (no authentication required for comment submission per the CVE description, though this conflicts with the PR:L CVSS metric - see confidence notes). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Despite a moderate CVSS base score of 5.4 (Medium), the real-world impact of this vulnerability significantly exceeds the raw score due to the admin-context execution model. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified in the provided data; patch availability should be confirmed directly with the module author at https://github.com/xpert-idea/xipblog. … Detailed patch versions, workarounds, and compensating controls in full report. |
