CVE-2023-36260 is a high-severity (CVSS 7.5) CWE-74 vulnerability in craftcms/cms. O3 Security confirms whether CVE-2023-36260 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Craft CMS Feed-Me
Real-World Exposure
craftcms/cmsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
An issue was discovered in the Feed Me plugin 4.6.1 for Craft CMS. It allows remote attackers to cause a denial of service (DoS) via crafted strings to Feed-Me Name and Feed-Me URL fields, due to saving a feed using an Asset element type with no volume selected. NOTE: this is not a report about code provided by the Craft CMS product; it is only a report about the Feed Me plugin. NOTE: a third-party report states that commit b5d6ede51848349bd91bc95fec288b6793f15e28 has "nothing to do with security."

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for craftcms/cms. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update craftcms/cms to 4.6.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-36260 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2023-36260 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2023-36260. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
