This medium-severity CVE scores 5.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2% (3rd percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Joomla Extension - svenbluege.de - Cross-site request forgery of list tasks of the backend in Event Gallery extension < 6.6.0 - Eight tasks which the buttons of the back-end lists call did not check the form token: setting the default payment method, shipping method, image type set, order status and watermark; putting an event into the shop or taking it out; choosing the main image of an event and whether an image is shown only as the main image; and sorting the images of an event. A prepared page on another web site could trigger them in the name of a logged in administrator and change those settings and flags. Nothing can be deleted or read this way; orders are not affected.

CISA SSVC: Track at low or medium mission impact; Attend at high (mission-essential systems).
Action: No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
