Successful exploitation would allow the attacker to retrieve sensitive information belonging to other tenants, compromising confidentiality and potentially affecting integrity if the data is tampered with."}}}}, "created": "2026-02-10T11:35:09.519468+00:00", "updated": "2026-04-17T21:15:27.386847+00:00", "vendors": ["praskla-technology", "praskla-technology$PRODUCT$assessment-placipy"]}
