CVE-2025-30081

Clickstorm SEO Allows Cross-Site Scripting (XSS)

A cross-site scripting (XSS) vulnerability has been discovered in the Clickstorm SEO extension. This vulnerabily is exploitable by a logged in backend user utilizing the TYPO3 backend user interface. This user can create output in the HTML context by exploiting improperly encoded user input. Updates 6.7.0, 7.4.0, 8.3.0 and 9.2.0 are available for download.

Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.

CVE-2025-30081 has a CVSS score of 5.9 (Medium). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (9.2.0, 8.3.0, 7.4.0, 6.7.0); upgrading removes the vulnerable code path.

5. Is CVE-2025-30081 exploitable, and should I be worried? Whether CVE-2025-30081 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2025-30081 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
