Users who are listed as shared members of a RecipeBook, who are supposed to have read\u2011only access, can therefore delete or overwrite the entire book. This results in unauthorized data modification and effectively elevates a read\u2011only user to have full control over the targeted RecipeBook.", "risk_and_exploitability": "The CVSS score of 8.1 reflects a high severity of the defect, indicating significant impact if exploited. No EPSS data is available, and the vulnerability is not listed in the CISA KEV catalog, suggesting no confirmed exploits to date. The attack requires authenticated access as a user who has been granted shared read\u2011only rights; the attacker can then issue DELETE or PUT HTTP requests against the shared RecipeBook API endpoints. Because the flaw lies in the permission layer, exploitation is straightforward for anyone with shared access, making the vulnerability highly actionable for malicious insiders or compromised shared users."}}}}, "created": "2026-04-08T19:37:19.225046+00:00", "updated": "2026-04-08T19:48:37.091941+00:00", "vendors": ["tandoorrecipes", "tandoorrecipes$PRODUCT$recipes"]}
