CVE-2026-12992: A flaw was found in Apicurio Registry

Routine

HIGH 7.4WATCHLISTUPGRADE

CVE-2026-12992 is a high-severity flaw (CVSS 7.4) affecting build of apicurio registry. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A flaw was found in Apicurio Registry. The WSDLReaderAccessor creates a wsdl4j WSDLReader without disabling the javax.wsdl.importDocuments feature. When the VALIDITY rule is set to FULL, an attacker with Developer-role access can upload a WSDL document containing attacker-controlled import locations, causing the registry to issue HTTP requests to arbitrary internal URLs (server-side request forgery).

redhat build of apicurio registry UPGRADE

Affected: >= 3.0 and <= 3.2

Fixed in: newer than 3.2

Safe to downgrade to: a release before 3.0

1. Check installed version

apt-cache policy build-of-apicurio-registry || rpm -q build-of-apicurio-registry || build-of-apicurio-registry --version

2. UPGRADE to newer than 3.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade build-of-apicurio-registry

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade build-of-apicurio-registry

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 3.0 (Debian / Ubuntu)

apt-cache madison build-of-apicurio-registry sudo apt install build-of-apicurio-registry=<VERSION_BEFORE_3.0> sudo apt-mark hold build-of-apicurio-registry

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list build-of-apicurio-registry sudo dnf downgrade build-of-apicurio-registry-<VERSION_BEFORE_3.0> sudo dnf versionlock add build-of-apicurio-registry

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
