CVE-2026-70551: 
Artifactory Schwachstellenanalyse und -minderung

CVE-2026-70551 is a Server-Side Request Forgery (SSRF) vulnerability in JFrog Artifactory, described as "Server-Side Request Forgery Via VCS Remote Download." An authenticated user with read access to an existing remote VCS (Version Control System) repository can replace its configured origin or supply an absolute VCS data URL, potentially redirecting repository operations to attacker-controlled sources. It affects JFrog Artifactory self-managed versions 7.161.0 through 7.161.17 and 7.146.0 through 7.146.35. The vulnerability was published on August 25, 2026, and carries a CVSS v3.1 base score of 8.5 (High) (JFrog Advisory, Github Advisory).

The vulnerability is classified as CWE-918 (Server-Side Request Forgery), where Artifactory's VCS remote download functionality fails to sufficiently validate or restrict the origin URL or absolute VCS data URL supplied by an authenticated user (Github Advisory). An attacker with read-level access to a remote VCS repository can manipulate the repository's configured origin or inject an arbitrary absolute URL, causing the Artifactory server to issue outbound requests to attacker-controlled destinations. The attack requires network access and low privileges (read access to a remote VCS repository), with no user interaction needed, and the scope change (S:C) indicates that the impact extends beyond the vulnerable component itself. No public proof-of-concept code has been identified (JFrog Advisory).

Successful exploitation allows an authenticated attacker to redirect Artifactory's server-side VCS download requests to arbitrary external destinations, resulting in high confidentiality impact (e.g., exfiltration of repository data or internal network responses) and low integrity impact (e.g., substitution of repository content). Availability is not directly impacted. Because the scope is changed, the vulnerability can affect resources and systems beyond the Artifactory instance itself, including internal services reachable from the Artifactory server, raising the risk of internal network reconnaissance or data interception (JFrog Advisory, Github Advisory).

There is no evidence of active in-the-wild exploitation or a public proof-of-concept at this time (Github Advisory). The NVD SSVC assessment rates exploitation as "none" and the technical impact as "partial." The EPSS score is approximately 0.178% (7th percentile), indicating a low near-term exploitation probability. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires authenticated access with at least read permissions on a remote VCS repository, limiting the attack surface compared to unauthenticated vulnerabilities.

1. Reconnaissance: Identify a JFrog Artifactory self-managed instance running a vulnerable version (7.161.0–7.161.17 or 7.146.0–7.146.35) with at least one remote VCS repository configured.
2. Authenticate: Log in to Artifactory with a low-privileged account that has read access to the target remote VCS repository.
3. Identify target repository: Enumerate accessible remote VCS repositories via the Artifactory REST API or UI to find one whose origin can be modified.
4. Inject malicious URL: Using the Artifactory API or UI, replace the remote VCS repository's configured origin with an attacker-controlled URL, or supply an absolute VCS data URL pointing to an internal or external attacker-controlled server.
5. Trigger server-side request: Initiate a VCS download or repository sync operation, causing the Artifactory server to issue an outbound HTTP/HTTPS request to the attacker-controlled destination.
6. Collect data: Capture the request at the attacker-controlled server to harvest credentials, tokens, internal network information, or repository content returned by Artifactory (JFrog Advisory, Github Advisory).

• Network: Unexpected outbound HTTP/HTTPS requests from the Artifactory server to external or unusual internal IP addresses or hostnames, particularly during VCS repository sync or download operations.
• Logs: Artifactory access logs showing VCS remote repository configuration changes (origin URL modifications) by non-administrative users; log entries reflecting outbound requests to unfamiliar or attacker-controlled URLs during VCS operations.
• Configuration: Remote VCS repository origin URLs changed to external, non-standard, or IP-based addresses not matching the organization's approved VCS hosts.
• Process/Behavior: Repeated or anomalous VCS sync/download triggers by low-privileged accounts, especially shortly after repository configuration changes.

JFrog has released patched versions addressing CVE-2026-70551 for self-managed deployments: upgrade to 7.161.19 (for the 7.161.x branch) or 7.146.36 (for the 7.146.x branch). JFrog Cloud environments have already been automatically patched and require no action. As interim mitigations, restrict read access to remote VCS repositories to trusted users only, implement URL validation and whitelisting for VCS origins, and audit repository configuration changes regularly (JFrog Advisory, Artifactory Releases).

JFrog disclosed CVE-2026-70551 as part of a broader batch of Artifactory security advisories published on August 25, 2026, alongside several other vulnerabilities of varying severity. The advisory was catalogued by standard vulnerability tracking services including VulnDB, Vulners, and CVEFeed shortly after publication. No notable independent researcher commentary, social media discussion, or significant media coverage specific to this CVE has been identified beyond routine aggregation by vulnerability intelligence platforms.
