Mealie1.0.0beta3 is vulnerable to user enumeration via timing response discrepancy between users and non-users when an invalid password message is displayed during an authentication attempt.

Mealie 1.0.0beta3 was discovered to contain an Insecure Direct Object Reference (IDOR) vulnerability which allows attackers to modify user passwords and other attributes via modification of the userid parameter.

Mealie 1.0.0beta3 employs weak password requirements which allows attackers to potentially gain unauthorized access to the application via brute-force attacks.

A stored cross-site scripting (XSS) vulnerability in Mealie v0.5.5 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Shopping Lists item names text field.
