This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Before DolphinScheduler version 3.1.0, the login user could delete UDF function in the resource center unauthorized (which almost used in sql task), with unauthorized access vulnerability (IDOR), but after version 3.1.0 we fixed this issue. We mark this cve as moderate level because it still requires user login to operate, please upgrade to version 3.1.0 to avoid this vulnerability

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.dolphinscheduler:dolphinscheduler-api. 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 org.apache.dolphinscheduler:dolphinscheduler-api to 3.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-49620 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-2023-49620 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-2023-49620. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
