An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

Camaleon CMS through 2.9.2, fixed in commit 88ab703, contains a missing authorization vulnerability on the drafts endpoint that allows any authenticated low-privileged user to create draft posts by bypassing role and permission checks. Attackers can send requests to the drafts endpoint using only session authentication to create unauthorized drafts that appear in the administrative drafts queue.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
