Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @mozilla/readability, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update @mozilla/readability to 0.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-2792 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-2792 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-2792. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
