lodashnpmlodash-esnpmlodash.picknpmDescription
Versions of lodash prior to 4.17.19 are vulnerable to Prototype Pollution. The functions pick, set, setWith, update, updateWith, and zipObjectDeep allow a malicious user to modify the prototype of Object if the property identifiers are user-supplied. Being affected by this issue requires manipulating objects based on user-provided property values or arrays.
This vulnerability causes the addition or modification of an existing property that will exist on all objects and may lead to Denial of Service or Code Execution under specific circumstances.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for lodash, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update lodash to 4.17.19 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p6mc-m468-83gw is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
In OpenShift ServiceMesh (OSSM), Red Hat OpenShift Jaeger (RHOSJ) and Red Hat OpenShift Container Platform (RHOCP), the affected containers are behind OpenShift OAuth authentication. This restricts access to the vulnerable nodejs-lodash library to authenticated users only, therefore the impact is low. Red Hat…
