CVE-2026-112181—

——11Vulnerability due to inadequate restriction of references to external XML entities in OpenKM Community Edition. The XML processing in FormUtils / LocalEntityResolver does not properly restrict the resolution of external resources. An authenticated remote attacker with the ROLE_USER role can exploit the flaw via a REST request. In the 6.3.x branch, this allows the attacker to trigger HTTP requests under their control (SSRF); in 7.0.3, it allows the attacker to read local files and access internal HTTP resources from the server.2d CVE-2026-1189756.5 MÉD

——7In Progress® Telerik® Reporting prior to version 20.3.26.1110, improper restriction of XML external entity references in the SVG processing engine allows an authenticated attacker with low privileges who can supply SVG content to a report to read local or UNC files, or trigger server-side network requests, from the report rendering host. External XML entities in SVG content were resolved without applying the configured strict resource resolver and report path validation. Disclosed content is limited by the permissions of the rendering process and by what the rendered report output exposes.2d CVE-2026-918765.5 MÉD

——1Dell OpenManage Ansible Modules, versions 2.0.4 through 10.0.3, contains an Improper Restriction of XML External Entity Reference vulnerability in the XML parsing component. A low privileged attacker with local access could potentially exploit this vulnerability, leading to information exposure.3d CVE-2026-1051537.7 ALT

——12Improper Restriction of XML External Entity Reference in Apache Roller 4.0 through 6.1.6 allows an authenticated user with no weblog permissions to read files readable by the Roller process and cause the server to issue outbound HTTP requests to attacker-chosen destinations, by submitting a crafted Atom entry to the AtomPub endpoint. The entry body is parsed with a parser configuration that permits external parameter entities and external DTD subsets, and the parse happens before any per-weblog authorization check and before any check of whether the AtomPub feature is enabled, so the endpoint is reachable by any authenticated account on a default installation. Users are recommended to upgrade to Apache Roller 6.1.7 or later, which parses AtomPub entries with a hardened XML configuration and rejects AtomPub requests while the feature is disabled.3d CVE-2026-90993—
