WordPress Podlove Podcast Publisher <3.5.6 - SQL Injection

id: CVE-2021-24666

info:
  name: WordPress Podlove Podcast Publisher <3.5.6 - SQL Injection
  author: theamanrawat
  severity: critical
  description: |
    WordPress Podlove Podcast Publisher plugin before 3.5.6 is susceptible to SQL injection. The Social & Donations module, not activated by default, adds the REST route /services/contributor/(?P<id>[\d]+) and takes id and category parameters as arguments. Both parameters can be exploited, thereby potentially enabling an attacker to obtain sensitive information, modify data, and/or execute unauthorized administrative operations.
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to execute arbitrary SQL queries, potentially leading to unauthorized access, data manipulation, or data leakage.
  remediation: Fixed in version 3.5.6.
