claude-memnpmDescription
A weakness has been identified in thedotmack claude-mem up to 11.0.1. The affected element is the function computeObservationContentHash of the file src/services/sqlite/observations/store.ts of the component Observation Content Hash Handler. This manipulation causes use of weak hash. The attack can only be executed locally. The attack's complexity is rated as high. The exploitability is described as difficult. Upgrading to version 12.0.0 is sufficient to fix this issue. Patch name: f32fda8b35e9fe9329f87da65c31149362a03f97. It is suggested to upgrade the affected component.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for claude-mem. 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 claude-mem to 12.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-11330 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-2026-11330 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-2026-11330. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
