RESTful Web Services: Exposure of Sensitive Information Through Data Queries
CVE-2024-13255 is a high-severity exposure of sensitive information through data queries vulnerability in RESTful Web Services from Drupal, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 7.x-2.10 as the first without the flaw, so updating RESTful Web Services to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.51% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update RESTful Web Services to 7.x-2.10 or a later version.
- Read the advisory on drupal.org for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
