CrafterCMS: Transmission of Private Resources into a New Sphere
CVE-2025-0502 is a critical-severity transmission of private resources into a new sphere vulnerability in CrafterCMS, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 4.0.8, 4.1.6 as the first without the flaw, so updating CrafterCMS to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.46% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update CrafterCMS to 4.0.8 or 4.1.6, whichever matches your release line, or a later version.
- Read the advisory on craftercms.com for workarounds and exact fixed builds.
