Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for studio-42/elfinder, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update studio-42/elfinder to 2.1.61 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-26960 is resolved across your whole dependency graph.
Workarounds
Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
