Descrição técnica

PhpSpreadsheet is a pure PHP library for reading and writing spreadsheet files. Prior to 1.30.7, 2.1.19, 2.4.8, 3.10.8, and 5.10.0, Worksheet\Drawing::setPath validates only the initial external-image URL with setIsWhitelisted when setAllowExternalImages is enabled. The HTTP stream context permits PHP to follow a redirect without applying the callback to the redirected URL, so a permitted image host can redirect the server to an internal address and cause a blind GET request. The response body is not returned to the attacker because the reader validates the downloaded content as an image and removes the temporary file, but internal GET-driven endpoints, network reachability, and cloud metadata endpoints may be reached. This issue is fixed in versions 1.30.7, 2.1.19, 2.4.8, 3.10.8, and 5.10.0.

CVE-2026-1244876.5 MÉD

—

———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.1h 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.1h CVE-2026-1244667.2 ALT

—

———OpenEMR before 8.4.0 contains a server-side request forgery vulnerability that allows unauthenticated attackers to make the server send HTTP requests by registering an OAuth2 client with an unvalidated jwks_uri. Attackers can trigger the fetch via the token introspection endpoint with an unsigned client_assertion to probe internal services and reach cloud metadata endpoints.1h CVE-2026-1244426.5 MÉD

—

———AzuraCast before 0.24.0 contains a server-side request forgery vulnerability that allows users with station WebHooks permission to bypass the UserUrlFilter SSRF guard through HTTP redirects. Attackers can configure Mastodon, Telegram, GroupMe, or RadioReg webhooks pointing to a redirecting URL, causing the Guzzle client to reach internal services and expose responses via test logs.1h 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.1h 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.1h
