Articles & Coverage 1
AnalysisAI
Reflected/stored Cross-Site Scripting in the MapPress Maps for WordPress plugin (versions 2.97.3 and earlier) allows an unauthenticated remote attacker to inject malicious JavaScript that executes in the browser of a victim who interacts with a crafted link or page. Because the CVSS scope is changed (S:C), the injected script can act beyond the vulnerable component to affect logged-in users including administrators. …

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 open an attacker-crafted link or visit a page where the malicious MapPress input is reflected/rendered, so this cannot be triggered fully autonomously against a passive server. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed-to-moderate. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a URL or page containing a malicious JavaScript payload that is reflected through a MapPress parameter and sends it to a target - for example a WordPress administrator - via email or a forum link. When the victim clicks the link, the script executes in their authenticated browser session, and because scope is changed it can steal session cookies, perform actions as the victim, or pivot toward account takeover. … |
| Remediation | Upgrade the MapPress Maps for WordPress plugin to the first release published after 2.97.3 (the input does not specify an exact fixed version, so confirm the patched build via the WordPress plugin repository or the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/mappress-google-maps-for-wordpress/vulnerability/wordpress-mappress-maps-for-wordpress-plugin-2-97-3-cross-site-scripting-xss-vulnerability before deploying). … Detailed patch versions, workarounds, and compensating controls in full report. |
