Description
WACRM is a self-hostable CRM template for WhatsApp. In version 0.7.0 and earlier, WACRM flow and automation write routes authenticate account viewers but do not enforce the agent role before using a service-role database client that bypasses row-level security. In src/app/api/flows/[id]/route.ts, src/app/api/flows/[id]/activate/route.ts, and src/app/api/flows/route.ts, a viewer can create, edit, activate, or delete flows because membership-only checks are followed by service-role writes. In src/app/api/automations/route.ts and src/app/api/automations/engine/route.ts, a viewer can create active automations and trigger outbound WhatsApp actions without the role required by the underlying write policies. This can permit unauthorized workflow changes, destructive flow deletion, and outbound actions from a role intended to be read-only. This vulnerability is fixed with commit 03e851bea56dcf6bb21ff1b80ba531372bf3269f.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of the affected component has shipped for CVE-2026-77239 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-2026-77239 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-77239. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-77239 in your dependencies?
O3 Security finds CVE-2026-77239 across dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
