Unauthenticated Cross Site Scripting (XSS) in Modula - PRO <= 2.10.8 versions.
AnalysisAI
Cross-site scripting in the Modula PRO WordPress gallery plugin (versions through 2.10.8) allows unauthenticated remote attackers to inject arbitrary JavaScript that executes in a victim's browser when they view or interact with attacker-influenced content. Reported by Patchstack and rated CVSS 7.1 with a scope change, the flaw requires user interaction but no authentication; no public exploit identified at time of analysis and it is not listed in CISA KEV.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires no authentication (PR:N) but does require victim user interaction (UI:R) - such as clicking a crafted link or viewing a page containing the injected payload - against a site running Modula PRO version 2.10.8 or earlier. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L yields 7.1 (High): network-reachable, low complexity, and unauthenticated (PR:N), but exploitation is gated by required user interaction (UI:R) and impact is limited to Low across confidentiality, integrity, and availability - consistent with browser-context script execution rather than server compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a URL or submits input that carries a malicious JavaScript payload into a Modula PRO-rendered page and lures a logged-in administrator or site visitor to open it (satisfying the UI:R requirement). When the victim's browser renders the unsanitized content, the script runs in their session - potentially stealing cookies, forging admin actions, or redirecting the user. … |
| Remediation | Upgrade Modula PRO to the first fixed release above version 2.10.8 as published by the vendor; consult the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/modula/vulnerability/wordpress-modula-pro-plugin-2-10-8-cross-site-scripting-xss-vulnerability) and the vendor's changelog for the exact patched version, since no specific fix version is confirmed in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: scan all WordPress installations to identify deployed instances of Modula PRO v2.10.8 or earlier; immediately deactivate and remove affected plugin versions. …
