CVE-2026-19902
Description détaillée
The Ad Inserter – Ad Manager & AdSense Ads plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the Referer header in all versions up to, and including, 2.8.18 due to insufficient input sanitization and output escaping on the '{search-query}' dynamic tag. When an ad block's code contains that tag, replace_ai_tags() reads $_SERVER['HTTP_REFERER'] and tests it with the regex /[\.\/](google|yahoo|bing|ask)\.[a-z\.]{2,5}[\/]/i. The leading [\.\/] class matches a literal slash, so any referrer merely containing a segment such as '/google.com/' passes as a search-engine referral; the plugin then percent-decodes the referring query with parse_str() and substitutes the resulting 'q' (or 'p') value into the block via preg_replace() with no escaping. This makes it possible for unauthenticated attackers to execute arbitrary JavaScript in the context of the site for any visitor, including a signed-in administrator, by luring them to an attacker-controlled page that frames or links to any ordinary post. Exploitation requires the site to have an ad block whose code uses the '{search-query}' tag with automatic insertion enabled — a documented plugin feature used as intended.

CVE-2026-88789
Improper Restriction of XML External Entity Reference in the XSLT support extension (camel-quarkus-support-xalan) in Apache Camel Quarkus from 3.2.0 before 3.33.3 and from 3.34.0 before 3.40.0 on all platforms allows an attacker who supplies the XML document being transformed to read local files or issue requests to internal network locations via an external entity declaration in that document. The extension supplies its own Xalan-backed TransformerFactory to the xslt component and registers it as the JAXP default. Xalan-J 2.7.x predates JAXP 1.5 and does not honour javax.xml.XMLConstants.ACCESS_EXTERNAL_DTD or ACCESS_EXTERNAL_STYLESHEET, so the external access restrictions Apache Camel applies to the TransformerFactory it creates were not in effect. On the xslt component path this affects message bodies that reach the transformer already as a javax.xml.transform.Source; bodies of other types are converted to a SAXSource by Apache Camel with external entities and external DTD loading disabled, and are not affected. Because the factory is also the JAXP default, other code in the application obtaining one through TransformerFactory.newInstance() loses the same restrictions without error. Applications are affected if they use any of camel-quarkus-xslt, camel-quarkus-xslt-saxon, camel-quarkus-tika or camel-quarkus-xmlsecurity, each of which brings the XSLT support extension onto the classpath. For all but camel-quarkus-xslt, the exposure is limited to the JAXP default factory, since those extensions do not perform XSLT transformations themselves. Users are recommended to upgrade to version 3.33.3 or 3.40.0, which fixes this issue.
CVE-2026-82806
Exposure of data element to wrong session vulnerability in Apache APISIX. This issue affects Apache APISIX: from 2.3.0 before 3.7.0. Under a supported authz-keycloak configuration, a request's authorization scope could persist into later requests on the same route, leading to unintended authorization expansion and inconsistent access-control decisions. Users are recommended to upgrade to version 3.7.0 or higher, which fixes the issue.
CVE-2026-78242
Insertion of sensitive information into log file vulnerability in Apache APISIX. This vulnerability can cause the unmasked header value to be written to the log sink under a certain response structure. This issue affects Apache APISIX: 3.17.0. Users are recommended to upgrade to version 3.18.0, which fixes the issue.
