INCIBE-CERT Reports Critical Tankuam Places Account Takeover Flaw
Tech GuruQuick Answer
The authority published INCIBE-CERT CVE-2026-93556 for Kompini Tankuam Places deployments before the November 25, 2025 coordinated fix. INCIBE-CERT reports that the password-recovery endpoint did not bind its JWT to the requested user identifier, allowing an unauthenticated attacker to reset arbitrary accounts, including administrators. The authority states that Kompini fixed the service on November 25, 2025. Affected deployments should be matched to the authority's exact scope and moved to the supported fixed release.
Confirm Scope And Apply The Supported Fix
What to do now: Inventory Kompini Tankuam Places deployments before the November 25, 2025 coordinated fix, match the exact affected release or feature, apply the authority-supported fixed build or service remediation, validate the dependent workflow, and preserve evidence.

What Changed
INCIBE-CERT reports that the password-recovery endpoint did not bind its JWT to the requested user identifier, allowing an unauthenticated attacker to reset arbitrary accounts, including administrators. The authority states that Kompini fixed the service on November 25, 2025.
What To Validate Now
- Inventory. Locate Kompini Tankuam Places deployments before the November 25, 2025 coordinated fix deployments, versions, enabled features, exposure paths, owners, and dependent services.
- Establish applicability. Compare each deployment with the authority's affected-version statement: Tankuam Places deployments before the managed correction applied by Kompini on November 25, 2025. Do not infer applicability from product family or severity alone.
- Remediate. Apply The Kompini-managed correction applied November 25, 2025; obtain current service status from Kompini through the supported vendor or project channel, following the current advisory and change-control requirements.
- Validate. Confirm the resulting version or managed-service state, exercise representative functionality and recovery paths, monitor for regressions, and document exceptions.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Use the exact supported release stream and repository. Test dependencies, clusters, integrations, and rollback before broad deployment; a CVSS rating or reachable feature is not evidence of exploitation.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
