CVE-2026-65926: Information Disclosure Vulnerability

CVE-2026-65926 Overview

CVE-2026-65926 is an information disclosure vulnerability affecting JFrog Artifactory Release Bundle handling. An anonymous caller, when anonymous access is enabled, or a low-privilege authenticated user can learn the names and versions of private Release Bundles when the bundle name is known. The flaw is categorized under [CWE-862] Missing Authorization, indicating the affected endpoint does not correctly verify caller permissions before returning bundle metadata.

Critical Impact
Unauthorized users can enumerate private Release Bundle names and versions, exposing internal software distribution metadata that supports further reconnaissance.

Affected Products

JFrog Artifactory (Self-Managed) — versions listed in vendor advisory
JFrog Release Bundle functionality
Deployments where anonymous access is enabled or low-privilege accounts exist

Technical Details for CVE-2026-65926

Vulnerability Analysis

The vulnerability resides in the Release Bundle metadata lookup path within JFrog Artifactory. When a caller supplies a known bundle name, the service returns bundle name and version information without enforcing the authorization checks required for private bundles. This allows anonymous or low-privilege callers to confirm the existence of and enumerate versions for bundles they should not be able to see.

Release Bundles typically describe curated, signed collections of artifacts used in software distribution pipelines. Exposure of their names and versions gives attackers insight into internal release cadence, product naming, and candidate targets for supply chain reconnaissance. The disclosure is limited to metadata; the flaw does not permit modification or denial of service based on the CVSS vector.

Root Cause

The root cause is a missing authorization check on the endpoint that resolves Release Bundle names and versions. The handler treats bundle name knowledge as sufficient context to return metadata, rather than validating that the caller holds read permission on the private bundle. This maps to [CWE-862] Missing Authorization.

Attack Vector

Exploitation occurs over the network against the Artifactory API. An attacker needs prior knowledge or a reasonable guess of a Release Bundle name. When anonymous access is enabled, no credentials are required. Otherwise, any authenticated account, including one with minimal privileges, can query the endpoint and receive the disclosed name and version data.

No verified exploitation code is publicly available. See the JFrog Security Advisories for vendor-supplied technical detail.

Detection Methods for CVE-2026-65926

Indicators of Compromise

Repeated Artifactory API requests targeting Release Bundle metadata endpoints with varied bundle name parameters.
Anonymous or low-privilege session activity querying bundle lookup routes outside of normal CI/CD patterns.
Access log entries showing successful metadata responses to unauthenticated callers when anonymous access is enabled.

Detection Strategies

Review Artifactory access logs for enumeration patterns against Release Bundle endpoints and correlate with source IP reputation.
Baseline expected Release Bundle API consumers such as CI/CD systems, then alert on callers outside that baseline.
Flag anonymous requests reaching bundle metadata endpoints in environments where anonymous access should be disabled.

Monitoring Recommendations

Forward Artifactory request and audit logs to a centralized analytics platform for retention and correlation.
Monitor for spikes in 200-response bundle lookups tied to a single account or IP.
Track configuration drift on the anonymous access setting and alert on any re-enablement.

How to Mitigate CVE-2026-65926

Immediate Actions Required

Upgrade JFrog Artifactory to a fixed version as identified in the JFrog Artifactory Release Notes.
Disable anonymous access unless explicitly required by a specific integration.
Audit low-privilege accounts and remove unused or stale identities.

Patch Information

JFrog has addressed the missing authorization check in Artifactory Release Bundle handling. Refer to the JFrog Security Advisories for the exact fixed versions and the JFrog Artifactory Release Notes for upgrade guidance.

Workarounds

Disable anonymous access system-wide in Artifactory administration settings.
Restrict network access to the Artifactory API to trusted CI/CD and administrative sources.
Rename sensitive Release Bundles to values that are difficult to guess until patching is complete.

bash

# Configuration example: verify anonymous access is disabled
# In Artifactory: Administration > Security > Settings
# Uncheck "Allow Anonymous Access" and save

# Verify via REST API
curl -u admin:<token> \
  https://<artifactory-host>/artifactory/api/securityconfig \
  | jq '.anonAccessEnabled'
# Expected result: false
