What is CVE-2026-121433?

AzuraCast prior to version 0.24.0 is susceptible to a stored CSV formula injection vulnerability. This occurs when users with Media permission can submit crafted metadata titles, artists, or custom fields through the bulk media import API. This allows malicious actors to embed formula-prefixed metadata that executes when other users access exported CSV files using spreadsheet applications, potentially leading to unintended data exposure or manipulation.

Affected Version(s)

AzuraCast 0 < 0.24.0

AzuraCast 0.24.0
