CVE-2026-82267: Komodo Information Disclosure Vulnerability

CVE-2026-82267 Overview

CVE-2026-82267 affects Komodo through version 2.3.2, a build and deployment orchestration platform. The vulnerability exists in the /execute and /execute/{variant} handlers, which disclose internal resource identifiers and write audit entries before performing permission checks. Authenticated users can guess resource names to enumerate internal identifiers. They can also insert fraudulent audit log entries that misrepresent privileged operations. The flaw is classified as Missing Authorization [CWE-862].

Critical Impact
Authenticated attackers can enumerate internal resource identifiers and pollute audit logs with fraudulent entries claiming privileged operations, undermining forensic integrity.

Affected Products

Komodo versions up to and including 2.3.2
Komodo /execute API handler
Komodo /execute/{variant} API handler

Technical Details for CVE-2026-82267

Vulnerability Analysis

The vulnerability resides in Komodo's execute API layer. When an authenticated user submits a request to /execute or /execute/{variant}, the handler resolves the supplied resource name to an internal identifier and records an audit log entry before validating whether the caller holds the necessary permissions.

This ordering creates two distinct security problems. First, differential responses tied to resource resolution allow attackers to enumerate valid resource names and harvest internal identifiers. Second, the pre-authorization audit write persists entries describing privileged operations that were never authorized.

The underlying weakness maps to Missing Authorization [CWE-862]. The handlers assume identity verification is sufficient before performing sensitive lookups, when they should defer both identifier disclosure and audit writes until after the permission check succeeds.

Root Cause

The root cause is control-flow ordering in bin/core/src/api/execute/mod.rs and the update helper in bin/core/src/helpers/update.rs. Resource lookup and audit persistence run before the permission gate. Any authenticated principal, regardless of role, triggers these side effects.

Attack Vector

An authenticated attacker with low privileges sends crafted /execute or /execute/{variant} requests referencing guessed resource names. Response behavior confirms which names exist and returns the corresponding internal identifiers. Repeated submissions plant misleading audit records that reference higher-privilege actions. Refer to the VulnCheck Advisory on Komodo and GitHub Issue #1455 for exploitation details.

Detection Methods for CVE-2026-82267

Indicators of Compromise

Bursts of /execute or /execute/{variant} requests from a single authenticated user targeting many distinct resource names
Audit log entries referencing privileged operations that lack corresponding downstream state changes or executor activity
Requests from low-privilege accounts that name resources outside their assigned scope

Detection Strategies

Correlate Komodo audit log entries against actual execution outcomes and flag entries with no matching runtime effect
Baseline per-user request rates to the execute endpoints and alert on sudden name-enumeration patterns
Compare requested resource names against each account's authorized resource set to identify probing behavior

Monitoring Recommendations

Forward Komodo application logs and reverse proxy access logs to a centralized analytics platform for correlation
Track ratios of permission-denied outcomes to audit-log writes on /execute handlers and alert on divergence
Monitor authentication events for low-privilege accounts issuing high volumes of execute API calls

How to Mitigate CVE-2026-82267

Immediate Actions Required

Restrict network exposure of the Komodo API to trusted management networks and enforce strong authentication
Audit existing accounts and revoke unused or over-scoped credentials that can reach the execute endpoints
Review historical audit log entries generated by non-privileged accounts and validate against actual execution outcomes

Patch Information

At the time of publication, no fixed release beyond Komodo 2.3.2 is referenced in the NVD data. Track the upstream fix through the Komodo GitHub repository, GitHub Issue #1455, and the referenced source files execute module and update helper. Upgrade as soon as a patched release is available.

Workarounds

Place the Komodo API behind a reverse proxy that enforces additional authorization checks on /execute paths
Limit account provisioning so only trusted operators can authenticate to Komodo until an upstream patch is applied
Preserve tamper-evident copies of audit logs off-host so fraudulent entries can be reconciled during investigations

bash

# Example: restrict Komodo /execute endpoints at an nginx reverse proxy
location ~ ^/execute(/|$) {
    allow 10.0.0.0/24;   # management subnet
    deny  all;
    proxy_pass http://komodo_upstream;
}
