Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Melapress WP Activity Log allows DOM-Based XSS.
This issue affects WP Activity Log: from n/a through 5.6.3.
AnalysisAI
DOM-Based Cross-Site Scripting in Melapress WP Activity Log (all versions through 5.6.3) allows a low-privileged, authenticated attacker to inject malicious scripts into the browser DOM of a victim who interacts with crafted content, with scope impact extending beyond the plugin itself. The CVSS vector (PR:L/UI:R/S:C) indicates exploitation requires an existing WordPress account and victim interaction, but the changed scope means successful exploitation can compromise the victim's browser session across the broader WordPress environment. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a valid, low-privileged WordPress account (PR:L per CVSS vector) on the target site - unauthenticated external attackers cannot exploit this vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.5 (Medium) reflects a network-accessible, low-complexity attack requiring low privileges and user interaction with changed scope. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A low-privileged WordPress user (e.g., a contributor or editor on a multi-author site) submits content or performs an action that injects a crafted JavaScript payload into data recorded by the WP Activity Log plugin. When a WordPress administrator later navigates to the activity log page to review site events, the victim's browser executes the attacker's script in the admin's session context, potentially enabling session token theft, unauthorized admin actions, or account takeover. … |
| Remediation | Update WP Activity Log to the version released after 5.6.3; the exact patched version is not independently confirmed from the available reference data - verify the current release at the WordPress plugin repository or the Melapress vendor page and apply the latest available version. … Detailed patch versions, workarounds, and compensating controls in full report. |
