The issue occurs when the library processes an unsanitized deployment name. Due to a missing containment check, an attacker with the Deployer RBAC role can use path traversal sequences to access files outside the restricted deployment directory. This can allow the attacker to delete arbitrary directories or create files with arbitrary content, leading to a full privilege escalation to the management SuperUser role." } ], "affected": [ { "vendor": "Red Hat", "product": "Red Hat Fuse 7", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "wildfly-server", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:jboss_fuse:7" ] }, { "vendor": "Red Hat", "product": "Red Hat JBoss Enterprise Application Platform 7", "collectionURL": "https://access.redhat.com/jbossnetwork/restricted/listSoftware.html", "packageName": "jboss-eap-7/eap74-els-openjdk11-openshift-rhel8", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:jboss_enterprise_application_platform:7" ] }, { "vendor": "Red Hat", "product": "Red Hat JBoss Enterprise Application Platform 7", "collectionURL": "https://access.redhat.com/jbossnetwork/restricted/listSoftware.html", "packageName": "jboss-eap-7/eap74-els-openjdk17-openshift-rhel8", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:jboss_enterprise_application_platform:7" ] }, { "vendor": "Red Hat", "product": "Red Hat JBoss Enterprise Application Platform 7", "collectionURL": "https://access.redhat.com/jbossnetwork/restricted/listSoftware.html", "packageName": "jboss-eap-7/eap74-els-openjdk8-openshift-rhel8", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:jboss_enterprise_application_platform:7" ] }, { "vendor": "Red Hat", "product": "Red Hat JBoss Enterprise Application Platform 7", "collectionURL": "https://access.redhat.com/jbossnetwork/restricted/listSoftware.html", "packageName": "wildfly-server", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:jboss_enterprise_application_platform:7" ] }, { "vendor": "Red Hat", "product": "Red Hat JBoss Enterprise Application Platform 8", "collectionURL": "https://access.redhat.com/jbossnetwork/restricted/listSoftware.html", "packageName": "wildfly-server", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:jboss_enterprise_application_platform:8" ] }, { "vendor": "Red Hat", "product": "Red Hat JBoss Enterprise Application Platform Expansion Pack", "collectionURL": "https://access.redhat.com/jbossnetwork/restricted/listSoftware.html", "packageName": "wildfly-server", "defaultStatus": "unaffected", "cpes": [ "cpe:/a:redhat:jbosseapxp" ] }, { "vendor": "Red Hat", "product": "Red Hat Single Sign-On 7", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "wildfly-server", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:red_hat_single_sign_on:7" ] } ], "references": [ { "url": "https://access.redhat.com/security/cve/CVE-2026-85634", "tags": [ "vdb-entry", "x_refsource_REDHAT" ] }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2528476", "name": "RHBZ#2528476", "tags": [ "issue-tracking", "x_refsource_REDHAT" ] } ], "datePublic": "2026-10-15T00:00:00.000Z", "problemTypes": [ { "descriptions": [ { "cweId": "CWE-22", "description": "Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')", "lang": "en", "type": "CWE" } ] } ], "x_redhatCweChain": "CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')", "workarounds": [ { "lang": "en", "value": "Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability." } ], "timeline": [ { "lang": "en", "time": "2026-09-04T11:46:02.455Z", "value": "Reported to Red Hat." }, { "lang": "en", "time": "2026-10-15T00:00:00.000Z", "value": "Made public." } ], "providerMetadata": { "orgId": "53f830b8-0a3f-465b-8143-3b8a9948e749", "shortName": "redhat", "dateUpdated": "2026-10-15T16:08:26.875Z" }, "x_generator": { "engine": "cvelib 1.8.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-10-15T17:45:29.329011Z", "id": "CVE-2026-85634", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-10-15T17:46:17.836Z" } } ] } }
