CVE-2026-65923 Overview
CVE-2026-65923 is a Server-Side Request Forgery (SSRF) vulnerability in JFrog Artifactory's Ansible repository handling. The flaw stems from insufficient URL validation, allowing an authenticated user with specific repository access to trigger unintended server-side requests. The vulnerability is tracked under CWE-918 and affects confidentiality and integrity of the Artifactory instance and reachable internal services.
JFrog has addressed the issue in updated Artifactory releases. Exploitation requires low privileges and no user interaction, but attack complexity is high.
Critical Impact
An authenticated attacker can coerce the Artifactory server into issuing HTTP requests to attacker-chosen destinations, potentially exposing internal services, metadata endpoints, or sensitive repository data.
Affected Products
- JFrog Artifactory Self-Managed (versions prior to the fixed release)
- JFrog Artifactory Cloud instances running vulnerable versions
- Deployments with Ansible repositories configured and accessible to authenticated users

Technical Details for CVE-2026-65923
Vulnerability Analysis
The vulnerability resides in the Ansible repository handling logic within JFrog Artifactory. When Artifactory processes URLs associated with Ansible repository operations, the input validation routine fails to sufficiently constrain destination hosts, schemes, or IP ranges. An authenticated user with access to an Ansible repository can supply a crafted URL that Artifactory subsequently fetches on the server side.
The attack executes over the network and requires low privileges. Attack complexity is high because the attacker must satisfy specific repository access conditions and craft input that survives partial validation. Successful exploitation impacts both confidentiality and integrity. Availability is not directly affected.
SSRF flaws in artifact repositories are particularly consequential because Artifactory typically runs inside trusted network segments with access to CI/CD infrastructure, cloud metadata services, and internal registries.
Root Cause
The root cause is improper URL validation (CWE-918) in code paths that construct outbound requests for Ansible repository resources. The validator does not enforce a strict allowlist of destinations and does not block requests to loopback, link-local, or private address ranges.
Attack Vector
An authenticated user with access to an Ansible repository submits a request that causes Artifactory to resolve and fetch a URL controlled by the attacker. The server-side request inherits the network position and identity of the Artifactory process. Attackers can pivot to internal HTTP services, query cloud instance metadata endpoints, or probe internal network segments for reachable hosts.
Because no verified proof-of-concept is public, the exact request shape is not disclosed. See the JFrog Security Advisories for vendor-supplied technical details.
Detection Methods for CVE-2026-65923
Indicators of Compromise
- Outbound HTTP or HTTPS requests from the Artifactory service account to internal RFC1918 ranges, loopback addresses, or cloud metadata endpoints such as 169.254.169.254.
- Ansible repository API calls containing unusual URL parameters or references to non-Ansible hosts.
- Unexpected entries in Artifactory access and request logs correlating authenticated user activity with outbound fetches to unrelated destinations.
Detection Strategies
- Review Artifactory request.log and access.log for Ansible repository endpoints followed by outbound connections to atypical hosts.
- Deploy network egress monitoring on the Artifactory host and alert on connections to internal-only subnets or metadata IPs.
- Correlate authenticated user identifiers with outbound URL fetch patterns to identify anomalous repository usage.
Monitoring Recommendations
- Enable verbose logging on Ansible repository handlers and forward logs to a centralized SIEM for retention and analysis.
- Baseline normal outbound destinations for the Artifactory service and alert on deviations.
- Monitor cloud audit logs (AWS CloudTrail, Azure Activity, GCP Audit) for unexpected instance metadata queries originating from the Artifactory host.
How to Mitigate CVE-2026-65923
Immediate Actions Required
- Upgrade JFrog Artifactory to a fixed version as listed in the JFrog Release Documentation.
- Audit user permissions on Ansible repositories and remove access from accounts that do not require it.
- Restrict egress network traffic from Artifactory hosts to only the destinations required for operation.
Patch Information
JFrog has released fixed Artifactory versions that correct URL validation in the Ansible repository handler. Refer to the JFrog Security Advisories for the specific fixed versions and upgrade guidance. Self-managed operators should schedule upgrades based on their change-control processes; cloud tenants should confirm patch status with JFrog support.
Workarounds
- Disable or remove Ansible repositories that are not actively used until patching is complete.
- Apply strict egress firewall rules that block Artifactory from reaching internal management networks, cloud metadata endpoints, and loopback interfaces.
- Enforce least-privilege access on remaining Ansible repositories by limiting write and configuration permissions to trusted service accounts only.
