Technical summary

The teddy-bear-customize-addon WordPress plugin through 1.0.5 does not properly validate uploaded files, relying on a client-supplied content type and preserving the original filename, allowing unauthenticated attackers to upload arbitrary PHP files and execute code on the server. The vulnerability affects WordPress installations with the teddy-bear-customize-addon plugin version 1.0.5 or earlier. Defenders should prioritize verifying exposure and assessing the feasibility of code execution due to improper file validation.

Defensive priority

Defenders should prioritize verifying exposure of the teddy-bear-customize-addon WordPress plugin version 1.0.5 or earlier, and assess the feasibility of code execution.

Recommended defensive actions

  • Verify exposure of the teddy-bear-customize-addon WordPress plugin version 1.0.5 or earlier
  • Assess the feasibility of code execution
  • Consider restricting file uploads or implementing additional validation
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
