———IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote attacker to obtain sensitive information due to an XML external entity (XXE) injection.5hCVE-2026-1238246.3 MED—
——0The Symfony Config component XmlUtils::parse() enables DTD validation before rejecting documents that carry a doctype, allowing XML external entity (XXE) injection in Symfony versions prior to 5.4.56, 6.x prior to 6.4.50, 7.x prior to 7.4.23, and 8.x prior to 8.1.11. A remote attacker who can supply XML to this method can determine whether local files exist, cause a denial of service, and, in some configurations, exfiltrate local file content via a crafted XML document whose doctype declares an external file:// entity.
XmlUtils::parse() sets $dom->validateOnParse = true before calling loadXML() and only rejects documents carrying a doctype afterwards. Enabling DTD validation makes libxml resolve external entities during loadXML(), and LIBXML_NONET blocks http:// but not file://, so a file:// entity is read from disk before the doctype rejection runs. The content of the file is not returned to the caller, but the distinct libxml error for a missing path reveals whether a file exists, and an entity pointing at a large or slow file causes a denial of service. If the application registers a network-capable stream wrapper such as s3://, a parameter entity can also send the content of a local file to an external server. This is the same issue as CVE-2026-45071, which was fixed in the DomCrawler component but not in Config.
Applications are affected if they pass untrusted XML to XmlUtils::parse() directly. The Symfony components that call it process developer-provided or operator-configured sources, such as configuration files and the XLIFF documents fetched by the translation providers.13hCVE-2026-1238574.3 MED—

——6XML External Entity (XXE) Injection in ContentWorker in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote authenticated attacker holding content-author permission to read arbitrary server files and trigger server-side request forgery by storing a crafted text/xml DataResource containing an external entity declaration, causing ContentWorker's rendering of that content — via renderContentAsText and related CMS/help render paths — to parse the stored XML using FreeMarker's default NodeModel.parse DocumentBuilderFactory, which enables neither FEATURE_SECURE_PROCESSING nor external-entity/DTD restrictions, resolving the external entity and returning its content in the rendered response. Users are recommended to upgrade to version 24.09.08, which fixes this issue.13hCVE-2026-1230297.5 ALT33.9%
