Descrição técnica

Incorrect Authorization vulnerability in ash-project ash_postgres allows a user to load destination records linked to a source record only through another tenant's join rows. When a many_to_many relationship, or a through relationship, is loaded with a lateral join (for example with a per-record limit or sort), AshPostgres.DataLayer builds the query for the join resource, and for each resource along a through path, in lateral_join_query/3 and through_step_queries/4 without running that resource's read action, which is where attribute multitenancy is applied. When those resources use strategy :attribute multitenancy, rows belonging to other tenants were joined, so the load returned destination records that the caller's tenant is not related to. This issue affects ash_postgres: from 0.38.0 before 2.15.2.

—

———OpenEMR before 8.4.0 contains an improper authorization vulnerability in the non-patient POST /fhir/DocumentReference/$docref route that allows low-privileged users to generate any patient's CCDA. Attackers with only demographics and documents permissions can supply a victim patient parameter, then download the full-chart CCDA from Patient Documents to exfiltrate clinical data.2h CVE-2026-1244838.3 ALT

—

———OpenEMR before 8.4.0 contains an incorrect authorization vulnerability because the prescription REST API routes check the patients.med ACL instead of patients.rx and request no specific permission bit, so read-only Medical/History access passes the check. Authenticated staff users can reuse the UI-exposed APICSRFTOKEN to enumerate prescription UUIDs, forge prescriptions for arbitrary patients, and deactivate existing prescriptions tenant-wide.2h CVE-2026-1244418.8 ALT

—

———Kyverno before 1.19.2 contains an authorization bypass vulnerability that allows namespaced tenants to generate any resource kind in any namespace by templating the generate rule's kind and namespace with variables. Attackers can create a Policy and trigger ConfigMap in their own namespace, causing the privileged background-controller to write NetworkPolicies or RoleBindings into victim or kube-system namespaces.2h CVE-2026-1244368.0 ALT

—

———OpenRemote before 1.32.2 contains an improper authorization vulnerability that allows realm administrators to access and modify global resources by calling admin endpoints lacking super administrator checks. Attackers can change the global keycloakUrl via /configuration/manager to redirect other realms' console authentication for credential phishing, inject CSS, replace map tiles, and delete logs.2h CVE-2026-1244336.5 MÉD

—

———phpMyFAQ before 4.1.11 contains an insufficient authorization vulnerability that allows delegated administrators holding only GROUP_DELETE permission to delete higher-privileged groups. Attackers can submit a target group_list_select value to /admin/group/confirm and then /admin/group/delete to remove privileged groups, their memberships, and permission mappings.2h CVE-2026-1235275.4 MÉD

—

———Vikunja from 2.4.0 before 2.7.1 contains an authorization bypass vulnerability that allows token holders to perform unintended operations due to colliding v1 and v2 API token permission keys. Attackers with a token scoped to read project backgrounds can delete them via the v2 DELETE background route, and bucket create-only tokens can update existing buckets.14h
