CVE-2021-24666Network attack vector

Published Sep 27, 2021 · Updated Aug 3, 2024

SQL injection in the Social & Donations module of Podlove Podcast Publisher before 3.5.6 allows remote attackers to execute SQL through a REST route. The contributor service lookup concatenates the id and category parameters into a raw WHERE clause without type enforcement or an allowlist. Exploitation requires the Social & Donations module to be enabled; successful queries can read or alter data accessible to the WordPress database account.
