Technical description

MoguBlog through 6.2 contains an XML external entity injection vulnerability in the WeChat callback handler at POST /wechat/wechatCheck. The WechatRestApi.index() method passes the raw request body to SignUtil.xmlToMap(), which uses an unhardened dom4j SAXReader without DTD or external-entity restrictions. Unauthenticated remote attackers can submit DOCTYPE declarations with external parameter entities to read arbitrary local files or trigger outbound HTTP requests, with resolved entities reflected in error responses.

———Improper restriction of XML external entity references in the RemoteQueryCachePlugin in AWS Advanced JDBC Wrapper 3.3.0 through 4.2.0 might allow an actor with write access to the shared cache infrastructure to disclose sensitive files from application hosts that read cached query results, including stored database and IAM role credentials, via crafted XML data in a cached column value. To remediate this issue, users should upgrade to version 4.3.0 or later.2h CVE-2026-825787.5 HIG

———When XML batch processing is turned on and the XPath option is selected, the raw batch input goes through a default XPath/JAXP setup with no entity restrictions, so XXE injection can allow data exfiltration and denial-of-service attacks.5h CVE-2026-782248.2 HIG

———The XSLT Transformer Step builds a bare TransformerFactory without the proper security options set, so XXE injection can allow data exfiltration and denial-of-service attacks.5h CVE-2026-892128.6 HIG

——0An information disclosure vulnerability in the SAML Single Sign-On (SSO) functionality of Omada Controller allows an authenticated user with SAML configuration privileges to access sensitive information due to insufficient validation of user-supplied SAML metadata. Successful exploitation could result in unauthorized disclosure of sensitive information.5h CVE-2026-195965.9 MED

——0An XML External Entity (XXE) vulnerability exists in the XML collector of multiple versions of OpenNMS Meridian and Horizon. When OpenNMS collects XML from a source whose response is attacker-controlled (for example a compromised monitored host or an HTTP man-in-the-middle position), the collector's XML parser resolves external entities and external DTDs. This allows an attacker to read files accessible to the OpenNMS service account, including database credentials, and to induce out-of-band requests. The solution is to upgrade to Meridian 2024.3.13, 2025.0.10 and Horizon 36.0.4 or newer. Meridian and Horizon installation instructions state that they are intended for installation within an organization's private networks and should not be directly accessible from the Internet.23h
