CVE-2026-18277
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk15th percentile - higher than 15% of all known CVEs
Summary
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
Risk Assessment
The risk includes unauthorized access to private OCR models, which could lead to confidentiality breaches. The attack requires authentication, but can be carried out by any logged-in user.
Recommendation
It is recommended to update Scripta eScriptorium to a version that contains the fix. Also, review user permissions and monitor activity related to OCR models.
