No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

Missing authorization in the OcrModelRight create and delete views in Scripta eScriptorium through 26.04.1 allows a remote authenticated user to grant themselves access to another user's private OCR model and to revoke any user's OCR model access via a POST request, because the ownership check is placed in get_context_data() and therefore runs only on the GET rendering path

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 (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). 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.
