Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-77240 exists.\n\nAffected product: ArnasDon wacrm. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-77240/ (Markdown: https://insights.sbomify.com/CVE-2026-77240/index.md)","id":"CVE-2026-77240","markdown":"https://insights.sbomify.com/CVE-2026-77240/index.md","name":"CVE-2026-77240","record":{"aliases":["GHSA-fg5p-2qc3-jmxr"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["privilege_escalation","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WhatsApp CRM template","requires_auth":"low_privilege","summary":"Authenticated users can bypass row-level security to self-promote roles, access other tenants' data, or modify tenant resources in WACRM.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"WACRM is a self-hostable CRM template for WhatsApp. In version 0.7.0 and earlier, the profiles_update row-level security policy in supabase/migrations/017_account_sharing.sql permits authenticated users to modify their own account_role and account_id, allowing a viewer to self-promote or move into another tenant and then access or modify tenant resources.
