Decidim is a participatory democracy framework, written in Ruby on Rails, originally developed for the Barcelona City government online and offline participation website. The templates module doesn't enforce the correct permissions, allowing any logged-in user to access to this functionality in the administration panel. An attacker could use this vulnerability to change, create or delete templates of surveys. This issue has been patched in version 0.26.8 and 0.27.4.
CVE-2023-36465
This critical-severity CVE scores 9.1 under NVD CVSS v3. EPSS exploit probability: 0.1%, top 79% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
