How to Fix GHSA-68r5-9hpg-7qw9
To remediate this vulnerability, upgrade all affected Opendj dsml servlet dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.openidentityplatform.opendj</groupId>
<artifactId>opendj-dsml-servlet</artifactId>
<version>5.1.2</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.openidentityplatform.opendjHow to Check if You Are Affected
To determine whether your Java application is affected by GHSA-68r5-9hpg-7qw9, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.openidentityplatform.opendjAnalyze the terminal output to locate any version of Opendj dsml servlet in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.1.2), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.openidentityplatform.opendj command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

"summary" : "OpenDJ unauthenticated SSRF, local file read and unbounded-read DoS in the DSMLv2 gateway",
"details" : "The DSMLv2 SOAP gateway (opendj-dsml-servlet) in OpenIdentityPlatform OpenDJ through 5.1.1 dereferences attacker-supplied xsd:anyURI values server-side without a scheme allowlist, egress filtering, or a size cap, and is reachable without authentication by default. A remote unauthenticated attacker can submit a DSML add/modify request whose value is a URI to (1) perform server-side request forgery against internal services and the cloud metadata endpoint (SSRF), (2) read local files via file: URIs, and (3) exhaust memory through an unbounded response read (DoS). Fixed in 5.1.2: anyURI dereferencing is disabled by default; when enabled it is limited to an http/https allowlist, rejects loopback/link-local/private/reserved targets, refuses HTTP redirects, and caps the bytes read. The gateway also now requires container-managed authentication by default.",
